Sermorelin (5 mg vial)

Protocol Overview

Concise summary of the regimen.

Dosing & Reconstitution

Frequency: Inject once daily subcutaneously at bedtime. Bedtime administration is strongly recommended because endogenous GH secretion peaks during sleep. For 10 unit (0.10 mL) or smaller administrations, consider

Reconstitution Steps

1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
2. Inject slowly down the vial wall; gently swirl to dissolve (do not shake vigorously).
3. Label with reconstitution date and refrigerate at 2 to 8 °C, protected from light.
4. Wipe vial stopper with alcohol before each use; use a new sterile needle and syringe for each injection. At 1.67 mg/mL, 1 unit = 0.01 mL » 16.7 mcg on a U-100 insulin syringe.

Storage Instructions

Proper storage preserves peptide quality.

• Lyophilized: store at 2 to 8 °C in dry, dark conditions; do not freeze dry powder; check expiration date.
• Reconstituted: refrigerate at 2 to 8 °C; do not freeze mixed solution; use within 10 to 14 days when using

bacteriostatic water.

• Allow vials to reach room temperature before reconstituting to aid dissolution; inspect solution before

each use (should be clear and colorless).

• Always use aseptic technique: swab stopper with alcohol before each draw; use new sterile needle and

syringe per injection.

Supplies Needed

Plan based on an 8 week daily protocol with gradual titration (56 injections total).

Peptide Vials (Sermorelin, 5 mg each):

• 8 weeks (total ~19.6 mg consumed): 4 vials (20 mg total).
• 12 weeks (similar daily range): 6 to 7 vials.
• Tip: Have 1 extra vial as backup in case of spillage or loss.

Insulin Syringes (U-100):

• Per week: 7 syringes (1/day).
• 8 weeks: 56 syringes (1 x 100-count box).
• 12 weeks: 84 syringes (1 x 100-count box).

Bacteriostatic Water (10 mL bottles):

• 8 weeks (4 vials): 12 mL (2 bottles). 12 weeks (7 vials): 21 mL (3 bottles).
• Contains benzyl alcohol preservative; do not use if allergic.

Alcohol Swabs:

• Per week: 14 swabs (2/day).
• 8 weeks: 112 (2 x 100-count). 12 weeks: 168 (2 x 100-count).

Important Notes

Practical considerations for consistency and safety.

• Bedtime dosing is critical: Sermorelin works best when administered before sleep to align with the

natural nocturnal GH pulse.

• Use new sterile insulin syringes; dispose in a designated sharps container after each use.
• Rotate injection sites systematically (abdomen, thighs, upper arms) to prevent irritation or

lipohypertrophy.

• Inject slowly subcutaneously; wait a few seconds before withdrawing the needle to ensure full delivery.
• Monitor IGF-1 levels at baseline and periodically (every 1 to 2 months) to confirm response and adjust

dosing if needed.

• Check thyroid function if using long-term, as subclinical hypothyroidism can blunt GH response.
• Document daily dose, time, and injection site in a log for adherence and troubleshooting.

How This Works

Sermorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) that binds to GHRH receptors on pituitary somatotropes, stimulating endogenous pulsatile GH secretion. Unlike exogenous GH administration, sermorelin preserves physiologic feedback loops: GH release is subject to normal negative feedback via somatostatin and IGF-1, reducing the risk of excessive GH or IGF-1 levels. This pulsatile GH output then promotes hepatic and peripheral IGF-1 production, supporting anabolic processes such as protein synthesis, lipolysis, and tissue repair. Pediatric studies in idiopathic GH deficiency demonstrated significant improvements in height velocity over 6 to 12 months of nightly subcutaneous therapy at 30 mcg/kg. In adults, off-label use aims to restore age-related declines in GH output, though robust adult trial data are limited. Sermorelin requires a functional pituitary to be effective and will not work in cases of pituitary damage or primary GH gene defects.

Benefits & Side Effects

Observations from pediatric clinical trials and adult off-label research.

• Stimulates endogenous pulsatile GH release, supporting physiologic IGF-1 elevation.
• Pediatric GH deficiency: significant improvements in height velocity and growth parameters over 6 to

12 months.

• Adults (off-label): may support favorable changes in body composition, energy, recovery, and metabolic

markers (evidence limited; effects more modest than direct GH therapy).

• Preserves physiologic feedback, reducing risk of supraphysiologic GH or IGF-1 levels compared to

exogenous GH.

• Injection-site reactions: transient redness, pain, or swelling at injection site (~17% incidence in trials).
• Rare systemic effects (under 1%): headache, flushing, dizziness, hyperactivity, drowsiness, or hives.
• Thyroid considerations: ~6.5% of patients developed subclinical hypothyroidism in one study;

untreated hypothyroidism can blunt GH response.

• No serious acromegaly, hypoglycemia, or excessive IGF-1 elevations reported at recommended

dosages.

Lifestyle Factors

Complementary strategies for best outcomes.

• Sleep quality: prioritize 7 to 9 hours of uninterrupted sleep nightly to maximize natural GH pulse and

sermorelin efficacy.

• Nutrition: consume adequate protein (1.6 to 2.2 g/kg/day) to support anabolic processes; avoid

high-carbohydrate meals immediately before bedtime (can blunt GH release).

• Exercise: combine resistance training (3 to 5 times weekly) and moderate aerobic activity to amplify

GH/IGF-1 benefits.

• Stress management: chronic stress elevates cortisol, which can suppress GH secretion.
• Avoid alcohol and smoking: both can impair GH release and blunt sermorelin response.

Injection Technique

General subcutaneous guidance from clinical best-practice resources.

1. Choose injection site: abdomen (at least 2 inches from navel), outer thigh, upper outer arm, or buttocks.
2. Clean vial stopper and skin: swab with alcohol; allow to dry completely.
3. Draw dose: remove needle cap; draw air equal to dose volume; inject air into vial; invert and draw prescribed dose; expel air bubbles.
4. Pinch and insert: pinch a fold of skin; insert needle at 45 to 90 degrees into subcutaneous tissue.
5. Inject slowly; wait 1 to 2 seconds before withdrawing needle at same angle.
6. Post-injection: apply gentle pressure with cotton ball or alcohol pad; do not rub the site.
7. Dispose immediately in designated sharps container; never recap needle.
