GLP-1 Starter Stack

Goal: Appetite suppression only — clean and simple

For people who want a GLP-1 and nothing else. Pick one compound based on your goal — Semaglutide is the most studied, Tirzepatide is stronger on appetite, Retatrutide is the most potent. Never combine two GLP-1 class compounds.

Compounds

Semaglutide OR Tirzepatide OR Retatrutide

Choose one. Start at the lowest dose and titrate slowly over 4–8 weeks.

Buy ↗

Cycle: 12–24+ weeks

🛡️

Immune and Longevity Stack

Goal: Immune resilience, T-cell support, anti-aging

Thymosin Alpha-1 is one of the most clinically documented immune peptides available. Epithalon activates telomerase and works well run alongside TA1 in a longevity protocol. These are not the same as the mitochondrial stack — this targets immune function and cellular aging, not energy metabolism.

Concentration (mg/mL) = Vial Mass (mg) ÷ Water Volume (mL)
Syringe Units (IU) = [Desired Dose (mcg) ÷ Concentration (mcg/mL)] × 100

Why BAC Water?

Contains 0.9% benzyl alcohol — keeps peptide viable for weeks in the fridge. Sterile water has no preservative.

Storage

Refrigerate 2–8°C. Keep away from light. Use within 4 weeks. Never freeze after reconstitution.

Syringe Math

100-unit insulin syringe = 1 mL. 10 IU = 0.1 mL. If 10mg in 2mL, each IU = 50 mcg.

Step-by-Step

1

Prep Your Workspace

Clean surface, wash hands. Swab tops of both vials with alcohol pads, let air dry 30 seconds.

2

Draw Your BAC Water

Use the calculator above. Common: 2 mL into 10 mg vial = 5 mg/mL.

3

Add Water to Peptide Vial

Aim stream down the SIDE of the vial, not directly onto powder.

Never spray onto powder. Never shake the vial. Both can denature the peptide.

4

Let It Dissolve

Gently swirl if needed. Most dissolve in minutes. Sit in fridge 15–30 min if not. Do not force it.

5

How To Vet a Vendor

Third-Party Testing (COA)Most Important

A legitimate vendor will have Certificates of Analysis from an independent lab — not their own testing. Look for HPLC or mass spectrometry reports. These confirm the compound is what it claims to be and at the stated purity.

Ask before buying if it's not on the site

Community PresenceEssential

Good vendors have verifiable track records on forums and communities like Reddit. Search the vendor name + "review" or "experience." Consistent positive feedback over time is the best signal. Fake reviews tend to be generic and recent.

Look for 6+ months of community history

Proper PackagingImportant

Peptides should arrive as lyophilized powder in sealed glass vials, typically with nitrogen purging. Vials should be properly labeled with compound name, batch number, and quantity. Loose powder in bags or unlabeled vials is a red flag.

Sealed vials, labeled, nitrogen purged

Transparent PricingImportant

Prices that are dramatically lower than the market average are a red flag. Quality synthesis, testing, and proper storage cost money. If it seems too cheap, the compound is likely underdosed, mislabeled, or impure.

Compare across 3+ vendors before buying

Responsive Customer ServiceGood Sign

Legitimate vendors respond to questions about sourcing, testing, and batch numbers. If a vendor deflects or ignores questions about their COAs, that tells you everything you need to know.

Test them before you buy

No Outrageous ClaimsCommon Sense

Vendors that make medical claims, promise guaranteed results, or use extreme before/after marketing are operating outside what's legally and ethically appropriate for research compounds. Stick to vendors that are factual and transparent.

Red flag: cure claims or miracle language

How To Read a COA

A Certificate of Analysis (COA) is a document from an independent third-party lab confirming what is in the vial. Here is what to look for and what each section means.

Identity Test

Confirms the compound is what the label says. Usually done by mass spectrometry (MS) or HPLC. The result should show a match to the reference standard for that peptide. If identity is not confirmed, stop there.

Should say: "Conforms" or "Match confirmed"

Purity Percentage

Shows how much of the content is actually the target peptide versus impurities. Research-grade peptides are typically 95%+ pure. Pharmaceutical grade is 98%+. Anything below 90% is concerning for injectable use.

Acceptable: 95%+ · Excellent: 98%+

HPLC Chromatogram

A graph showing peaks that represent different compounds in the sample. The main peak should be tall and sharp — that is your peptide. Small side peaks are impurities. A clean COA has one dominant peak with minimal noise.

One dominant peak = good. Multiple large peaks = impurities

Mass Spectrometry (MS)

The gold standard for peptide verification. Measures the molecular weight of the compound and compares it to the known weight of the peptide. If the molecular weight matches, the compound is correctly identified. Cannot be faked easily.

Molecular weight should match published peptide MW exactly

Lab Name and Date

The COA should come from a named, verifiable third-party laboratory — not the vendor's own internal testing. Check that the lab is real and that the test date is recent. COAs older than 12 months for a specific batch are a yellow flag.

Independent lab, dated within 12 months

Batch Number Match

The batch number on the COA should match the batch number on your vial. If a vendor gives you a COA with no batch number or a different number than what you received, the COA may not apply to your product.

COA batch = vial batch. No match = red flag

What a COA Cannot Tell You

COAs confirm identity and purity at time of testing — they do not guarantee your specific vial was handled correctly after testing, stored properly, or is still potent on arrival. Always check your reconstituted peptide looks correct before injecting.

COA is a starting point, not a guarantee

Red Flags in a COA

Watch for: no lab name listed, purity below 95%, no date, no batch number, generic format that looks copy-pasted, or a lab that does not appear in any online search. Some vendors fabricate COAs — if something looks off, trust your instincts.

No lab name or batch number = likely fake

Common Questions

Frequently Asked Questions

The most common questions from the community.

Basics

What syringe do I need for peptide injections?+

Use a 1mL insulin syringe with 100 units — typically 28–31 gauge, 5/16" needle. 31g is the most comfortable. BD Ultra-Fine and Easy Touch are solid brands. Buy in boxes of 100.

Can I mix two peptides in the same syringe?+

Yes, in most cases. CJC-1295 and Ipamorelin are commonly mixed in one injection. Draw one first, then the other. Avoid mixing peptides with very different pH levels. When in doubt, inject separately.

Where do I inject?+

Most peptides are injected subcutaneously (sub-Q) — just under the skin, not into muscle. Common sites: lower abdomen (pinch fat, inject at 45°), outer thigh, love handles. Rotate sites to avoid bruising.

How long does reconstituted peptide last?+

Reconstituted with BAC water and refrigerated, most peptides stay stable for 4–6 weeks. Keep away from light and heat. Lyophilized powder stored frozen can last 1–2+ years if sealed.

Do I need to fast before injecting?+

GH secretagogues (CJC-1295, Ipamorelin, GHRP-2, GHRP-6) work best fasted — carbs and fat blunt GH release. AOD-9604 and HGH Frag also best fasted. Healing peptides like BPC-157 and TB-500 do not require fasting.

Dosing and Cycling

What does "time off" mean and why does it matter?+

Time off prevents receptor desensitization — receptors downregulate from constant stimulation and the peptide becomes less effective. For GH secretagogues especially, running without breaks leads to diminishing returns. Common rule: time on equals time off.

How do I titrate GLP-1s like semaglutide?+

Start at 0.25 mg/week for 4 weeks. If tolerated, move to 0.5 mg/week, then 1 mg/week, and so on. Do not rush the titration — most severe nausea cases pushed too fast. GI sides are dose-dependent and improve over time.

What is the difference between CJC-1295 no DAC and DAC?+

No DAC: Short half-life, mimics natural GH pulse, inject 1–2x daily. With DAC: Long half-life (1–2 weeks), sustained GH bleed, inject 1–2x per week. Completely different mechanisms — do not substitute one for the other.

Should I use BPC-157 alone or the BPC/TB-500 blend?+

Use BPC-157 alone for localized gut issues or one specific injury. Use the blend for systemic recovery — multiple injuries, overall mobility, heavy training. TB-500 adds systemic anti-inflammatory effects that complement BPC.

Storage and Handling

Can I freeze reconstituted peptides?+

No. Freeze-thaw cycles degrade peptide chains. Once reconstituted, refrigerate only at 2–8°C. Unreconstituted powder can be frozen, but once water is added — refrigerate only.

Why does my peptide look cloudy after reconstitution?+

Some peptides like TB-500 appear slightly milky — that is normal. Visible particles, flakes, or heavy cloudiness that do not clear with gentle swirling is a red flag. When in doubt, do not use it.

How do I know if my peptide has gone bad?+

Signs of a compromised peptide:

Visible particles or heavy cloudiness
Yellow or brown discoloration
Unusual smell
No effect after multiple correct doses
Left unrefrigerated for extended time after reconstitution

If any apply, discard it.

Vendors and Sourcing

How do I vet a peptide vendor?+

Key things to look for:

Third-party testing (COA) — mass spec or HPLC reports showing purity
Transparent sourcing and active community presence
Responsive customer service
Proper packaging — lyophilized powder in sealed vials

Avoid vendors with no testing docs, no community presence, or suspiciously low prices.

Know Before You Run

Side Effects &
What To Do

What is normal, what is a red flag, and what to do about it. Most sides are manageable if you know them in advance.

💉

GLP-1s (Sema, Tirz, Reta)

Very Common

Nausea and vomiting — most common on ramp-up or dose increase.

Fix: Slow your titration. Dose at night. Avoid high-fat meals same day.

Constipation or diarrhea — GI motility slows significantly.

Fix: Increase fiber and water. Magnesium citrate at night. Do not rush to higher doses.

Muscle loss — rapid fat loss without training accelerates this.

Fix: Resistance train 3-4x per week. Hit protein targets daily.

Injection site redness or lump — normal for sub-Q early on.

Fix: Rotate sites every injection. Let solution warm to room temp before injecting.

🧬

GH Secretagogues (CJC, Ipa, GHRP)

Common

Water retention and bloat — GH increases water retention, especially early.

Fix: Reduce sodium. Usually resolves in 2-3 weeks. Lower dose if severe.

Carpal tunnel or tingling hands — pressure from fluid retention.

Fix: Lower dose or take a week off. Usually temporary.

Increased hunger (GHRP-6) — ghrelin stimulation drives appetite hard.

Fix: Switch to Ipamorelin. Or dose only at night.

Drowsiness — especially dosed before bed, which is intentional.

Fix: Keep nighttime dosing. Avoid pre-workout dosing.

💊

BPC-157 and TB-500

Generally Well Tolerated

Nausea (oral/sublingual BPC) — more common with oral routes.

Fix: Take with food or switch to injectable sub-Q.

Injection site irritation — mild redness or soreness.

Fix: Rotate sites, warm solution to room temp, inject slowly.

Cancer growth concern (theoretical) — angiogenesis promotion is the main debate.

Note: Do not use if you have a history of cancer or active tumors.

💊

NAD+

Common with IV

Flushing, chest tightness, nausea (IV) — common if drip rate is too fast.

Fix: Slow the drip. Run 250mg over minimum 2-4 hours.

Insomnia — energizing effect disrupts sleep if taken too late.

Fix: Take sub-Q or oral doses before noon.

Headache — usually dehydration-related during IV sessions.

Fix: Hydrate well before and during infusion. Electrolytes help.

🧪

Melanotan II and PT-141

Common

Nausea and facial flushing — very common especially first few uses.

Fix: Start at 0.5mg or lower. Dose at night.

Mole darkening (MT2) — increased pigmentation can darken existing moles.

Note: Get moles checked before and during use. Discontinue if moles change.

Increased blood pressure — transient spike after dosing.

Fix: Monitor BP. Avoid if you have cardiovascular issues.

⚠️

Universal Red Flags — Stop and Reassess

Important

Severe allergic reaction — rash, hives, difficulty breathing after injection. Stop immediately, seek emergency care.

Persistent elevated resting heart rate — especially with Retatrutide. Reduce dose or stop.

Pancreatitis symptoms — severe upper abdominal pain with GLP-1s. Stop immediately, get bloodwork.

Vision changes — blurring documented with GLP-1 use. Stop and see a doctor.

Blood sugar crashes — dizziness, sweating, confusion especially with IGF-1 LR3. Keep fast carbs nearby.

Cloudy or discolored peptide solution — never inject. Discard it.

Reminder

Side effects vary by individual, dose, and compound quality. This is not exhaustive. Not medical advice. If something feels wrong, stop the compound and consult a doctor.

Terminology

Peptide Glossary

Every term you will encounter in the peptide space, explained simply.

Agonist

A compound that binds to a receptor and activates it, mimicking or enhancing the body's natural signal.

Amino Acid

The building blocks of peptides and proteins. Peptides are chains of amino acids linked together.

Angiogenesis

Formation of new blood vessels. BPC-157 promotes this, aiding healing but debated in cancer contexts.

BAC Water

Bacteriostatic water. Contains 0.9% benzyl alcohol which prevents bacterial growth. The correct solvent for reconstituting peptides.

Bioavailability

Percentage of a dose that reaches systemic circulation. Injectable peptides are near 100%. Oral peptides are often destroyed in the gut.

COA

Certificate of Analysis. Third-party lab report showing purity and potency. Always ask vendors for this before buying.

DAC

Drug Affinity Complex. A modification on CJC-1295 that extends its half-life from 30 minutes to 1-2 weeks. Changes dosing frequency entirely.

Desensitization

When receptors downregulate from constant stimulation and a compound becomes less effective. Why cycling and time off matters.

GH (Growth Hormone)

Produced by the pituitary gland. Drives fat metabolism, muscle growth, recovery, and sleep quality. Most GH peptides work by stimulating its release.

GHRH

Growth Hormone Releasing Hormone. Signals the pituitary to release GH. CJC-1295 and Sermorelin are GHRH analogs.

GHRP

Growth Hormone Releasing Peptide. Stimulates GH release through the ghrelin receptor. Ipamorelin, GHRP-2, and GHRP-6 fall into this class.

GLP-1

Glucagon-Like Peptide-1. A gut hormone that slows gastric emptying and suppresses appetite. Semaglutide and Tirzepatide are GLP-1 receptor agonists.

Half-Life

How long it takes for concentration of a compound in the body to drop by 50%. Determines dosing frequency. Short half-life means dose more often.

HPLC

High-Performance Liquid Chromatography. Lab test used to verify peptide purity and identity. Gold standard for COAs.

IGF-1

Insulin-Like Growth Factor 1. Released by the liver in response to GH. Drives muscle cell growth and nutrient uptake into cells.

IM (Intramuscular)

Injected directly into muscle tissue. Used for some compounds like IGF-1 LR3 when targeting specific muscles.

Intranasal

Administered through the nose via a dropper or spray. Common for Semax, Selank, Oxytocin, and PT-141.

IU (International Units)

Unit markings on insulin syringes. On a 100-unit syringe, 100 IU = 1 mL. Dose in IU = (dose in mcg divided by concentration in mcg/mL) times 100.

Lyophilized

Freeze-dried. The form peptides come in from vendors. Must be reconstituted with BAC water before use. Maximizes stability and shelf life.

mcg (Microgram)

One millionth of a gram. 1,000 mcg = 1 mg. Most peptides are dosed in mcg.

mg (Milligram)

One thousandth of a gram. Used for larger doses — GLP-1s, TB-500, some GH peptides.

Myostatin

A protein that limits muscle growth. Follistatin-344 inhibits myostatin, theoretically allowing greater muscle development.

Peptide

A short chain of amino acids, typically 2-50 amino acids long. Smaller than proteins. Many occur naturally in the body as signaling molecules.

Pulsatile

Released in pulses rather than continuously. Natural GH secretion is pulsatile, mostly at night. Short-acting secretagogues mimic this.

Reconstitution

The process of dissolving lyophilized peptide powder in BAC water to create an injectable solution.

Secretagogue

A compound that stimulates the secretion of another substance. GH secretagogues signal the pituitary to release growth hormone.

SS-31 (Elamipretide)

A mitochondria-targeting peptide that concentrates in the inner mitochondrial membrane and protects cardiolipin. Used in longevity and energy optimization protocols. One of the more research-backed mitochondrial compounds available.

Sub-Q (Subcutaneous)

Injected just under the skin into the fat layer. The most common injection route for peptides. 45 degree angle, pinch the skin.

Telomere

Protective caps on chromosomes that shorten with age. Epithalon is believed to support telomere elongation, popular in longevity circles.

Titration

Gradually increasing a dose over time to assess tolerance and minimize side effects. Critical for GLP-1s — never jump straight to a high dose.

Triple Agonist

A compound that activates three receptors simultaneously. Retatrutide targets GLP-1, GIP, and glucagon receptors.

How To Inject

Injection Sites Guide

Where to inject, how to rotate, and what angle to use for sub-Q peptide injections.

Sub-Q Injection Sites

Lower Abdomen (Recommended)

Pinch 1-2 inches of fat, inject at 45 degrees. 1-2 inches below belly button, avoid the navel. Most recommended — easy access, good fat layer, minimal nerve density.

Love Handles / Flanks

Pinch fat on the side of the abdomen, inject at 45 degrees. Good rotation site when alternating away from the front. Plenty of fat, easy to pinch.

Outer Thigh

Middle outer portion of the thigh. Inject at 45-90 degrees depending on fat layer. Good rotation site. Avoid the inner thigh.

Technique

Swab site with alcohol. Let dry 30 seconds. Pinch skin. Insert at 45 degrees. Push plunger slowly. Hold 5 seconds. Remove and apply gentle pressure. Do not rub.

Rotation

Never inject the same spot twice in a row. Rotate systematically — left abdomen, right abdomen, left flank, right flank, left thigh, right thigh. Prevents lipodystrophy from repeated injections in one spot.

Injury-Specific (BPC-157)

Many users inject BPC-157 sub-Q near the injury site for localized effect. Still sub-Q — just closer to the target area. TB-500 is typically injected abdominally for systemic effect.

Important

Always use a fresh needle for every injection. Never reuse syringes. Dispose of used needles in a sharps container immediately. If you notice persistent lumps or signs of infection at a site — stop using it and see a doctor.

Lab Reference

Blood Work Guide

Suggested labs to run before, during, and after peptide protocols. Know your baseline and track what matters.

Why bloodwork matters: Most peptide side effects are detectable in labs before you feel them. Running baseline labs before you start and checking in mid-cycle lets you catch issues early, dial in your protocol, and have actual data to back up what you're feeling. Many of these are available through direct-to-consumer labs like Marek Health, Function Health, or your own doctor.

Universal Baseline — Run Before Any Protocol

Complete Blood Count (CBC)Essential

Checks red blood cells, white blood cells, platelets. Baseline health snapshot before starting anything.

RBC: 4.5–5.9 M/uL · WBC: 4.5–11.0 K/uL

Comprehensive Metabolic Panel (CMP)Essential

Liver enzymes, kidney function, electrolytes, blood sugar. Critical baseline before any compound.

ALT: 7–56 U/L · Creatinine: 0.7–1.3 mg/dL · Glucose: 70–99 mg/dL

Fasting Insulin + GlucoseEssential

GH peptides and IGF-1 affect insulin sensitivity. Need a baseline before running any GH secretagogue.

Fasting glucose: 70–99 mg/dL · Fasting insulin: 2–19 uIU/mL

HbA1cEssential

3-month average blood sugar. Important before GLP-1s and GH peptides. Flags pre-diabetes you may not know about.

Normal: below 5.7% · Pre-diabetic: 5.7–6.4%

Lipid PanelRecommended

Total cholesterol, LDL, HDL, triglycerides. GLP-1s improve lipids — good to track the change.

LDL: below 100 mg/dL · HDL: above 40 (M) / 50 (F)

Thyroid (TSH + Free T3/T4)Recommended

Thyroid affects metabolism, energy, and body composition. Some peptides interact with the thyroid axis.

TSH: 0.4–4.0 mIU/L · Free T4: 0.8–1.8 ng/dL

GLP-1s (Semaglutide, Tirzepatide, Retatrutide)

HbA1c + Fasting GlucoseEssential

Track glycemic improvement. Check before, at 8 weeks, and at end of cycle.

Target: HbA1c trending down toward normal

Lipase + AmylaseEssential

Pancreatitis risk marker. If you develop severe upper abdominal pain, get this immediately.

Lipase: 0–160 U/L · Amylase: 30–110 U/L

Comprehensive Metabolic PanelEssential

Monitor kidney and liver function throughout. Dehydration from GI sides can stress kidneys.

Check at baseline, 8 weeks, end of cycle

Lipid PanelRecommended

GLP-1s improve cholesterol and triglycerides. Tracking this shows one of the biggest benefits.

Expect LDL and triglycerides to decrease

DEXA Scan or InBodyRecommended

Track muscle vs fat loss ratio. Critical to confirm you are losing fat not muscle. Not a blood test but essential tracking.

Every 8–12 weeks

Calcitonin (Retatrutide)Recommended

Thyroid C-cell marker. Retatrutide carries a theoretical thyroid risk per FDA labeling. Baseline + monitoring recommended.

Normal: below 10 pg/mL

GH Secretagogues (CJC-1295, Ipamorelin, GHRP)

IGF-1Essential

Best indirect marker for GH activity. Run at baseline and mid-cycle to confirm GH is being stimulated and not overdone.

Optimal range varies by age — generally 150–350 ng/mL for adults

Fasting Glucose + InsulinEssential

GH raises blood sugar and reduces insulin sensitivity. Monitor throughout any GH protocol especially if predisposed to insulin resistance.

Fasting glucose should stay below 100 mg/dL

Cortisol (GHRP-2 and GHRP-6)Recommended

GHRP-2 and GHRP-6 raise cortisol. Check AM cortisol at baseline and mid-cycle if using these compounds.

AM cortisol: 6–23 mcg/dL

Prolactin (GHRP-2 and GHRP-6)Recommended

GHRP compounds can raise prolactin. Elevated prolactin causes libido issues and hormonal imbalance over time.

Normal male: 2–18 ng/mL · Female: 2–29 ng/mL

Thyroid PanelOptional

GH affects thyroid function. Worth checking if you notice unusual fatigue, weight changes, or temperature sensitivity.

TSH: 0.4–4.0 mIU/L

IGF-1 LR3 and Follistatin (Advanced)

Fasting Glucose + InsulinEssential

IGF-1 LR3 is the most potent insulin sensitizer on this list. Hypoglycemia risk is real. Monitor every 2 weeks during cycle.

Keep fast carbs on hand. Stop if glucose drops below 60 mg/dL

IGF-1Essential

Confirm you are in a reasonable range. Supraphysiologic IGF-1 for extended periods raises cancer risk theoretically.

Do not exceed 600 ng/mL during cycle

Comprehensive Metabolic PanelEssential

Liver and kidney baseline and monitoring throughout.

Check at baseline and end of cycle

Longevity Compounds (NAD+, Epithalon, TA1)

CBC + CMPEssential

General health baseline before and after longevity protocols.

Annually at minimum

Inflammatory Markers (CRP, IL-6)Recommended

TA1 and longevity peptides are often run to reduce systemic inflammation. Tracking CRP shows whether they are working.

High-sensitivity CRP: below 1.0 mg/L optimal

NK Cell Activity (Epithalon)Optional

Epithalon is claimed to improve immune function. NK cell panels track this but are expensive and niche.

Specialty test — not widely available

Telomere Length TestingOptional

If running Epithalon for telomere support, tracking telomere length over time is the only way to confirm it is working.

Available through Life Length or Repeat Diagnostics

Hormonal Health (General — Recommended for All)

Total + Free TestosteroneRecommended

Baseline hormonal health. GH peptides can improve testosterone indirectly. Good to track.

Total T: 300–1000 ng/dL · Free T: 9–30 pg/mL

LH + FSHRecommended

Relevant if running Kisspeptin-10. Confirms the compound is doing what it should upstream.

LH: 1.7–8.6 IU/L · FSH: 1.5–12.4 IU/L

Estradiol (E2)Recommended

GH can increase aromatization. Keep an eye on E2 especially if running long GH protocols.

Male optimal: 20–30 pg/mL

DHEA-SOptional

Adrenal health marker. Relevant if running longevity protocols or experiencing energy and recovery issues.

Male: 280–640 mcg/dL · Female: 65–380 mcg/dL

Important

These are suggested reference ranges only. Optimal ranges vary by age, sex, and individual baseline. Work with a licensed clinician to interpret your results. Direct-to-consumer options include Marek Health, Function Health, and Ulta Lab Tests. Not medical advice.

Quick Reference

From	To	Formula	Example
mg → mcg	mcg	mg × 1,000	0.5 mg = 500 mcg
mcg → mg	mg	mcg ÷ 1,000	250 mcg = 0.25 mg
mg → IU	IU on syringe	(mg ÷ conc mg/mL) × 100	0.5 mg @ 5 mg/mL = 10 IU
mcg → IU	IU on syringe	(mcg ÷ conc mcg/mL) × 100	500 mcg @ 5000 mcg/mL = 10 IU
IU → mL	mL	IU ÷ 100	10 IU = 0.1 mL

Note on IU

IU on a peptide syringe is not the same as international units used for vitamins or hormones. On a standard 1mL/100-unit insulin syringe, IU simply refers to the graduation marks. 10 IU = 0.1 mL.
