Ipamorelin

Pentapeptide · Selective GHS-R agonist · 5 amino acids

Half-life

~2h

After administration

Delivery Method

SubQ injection

Route of administration

Storage (Lyophilised)

12-24 months

2–8°C

Storage (Reconstituted)

4–6 weeks

Refrigerate at 2-8C

Known For

Growth hormone releasing peptide (GHRP). The 'cleanest' GHRP — minimal cortisol and prolactin increase unlike GHRP-2/6. Selective GH release. Great for sleep quality, recovery, and anti-aging.

Mechanism of Action

Selective GH secretagogue (ghrelin mimetic) — stimulates pituitary to release GH via ghrelin pathway WITHOUT stimulating cortisol, prolactin, or hunger (unlike GHRP-6).

Body vs. External Supply

🟢 Secretagogue (stimulates natural)

Brand / Trade Names

No pharmaceutical brand Research peptide only FDA Category 2 (2023)

Typical Research Dosage

100-300mcg per injection, 2-3x daily. Must be fasted.

Vial Duration Guide

5mg vial at 300mcg/day = ~17 days. 10mg at 300mcg/day = ~33 days.

Recommended Vial Size

★ 5mg vials At 300mcg/day, 5mg = ~17 days ✓. 10mg = 33 days ✓. 5mg for maximum freshness.

Time to Effects

EARLY: 2-4 weeks FULL: 8-12 weeks Week 1-2: Improved sleep, especially with bedtime dose. Week 2-4: Better recovery, subtle energy increase. Week 8-12: Body composition improvements. Much less effective alone — pair with CJC-1295 NO DAC for proper results. Minimum commitment: 8 weeks.

Contraindications & Do Not Combine

• Do NOT combine with exogenous HGH (pituitary suppression makes Ipa ineffective) • Can combine with ONE other GHRP if needed, but avoid stacking multiple GHRPs (diminishing returns, increased side effects)

Common Side Effects

Head rush/flushing (10%), headache, mild transient hunger (less than GHRP-6), injection site reaction

Drug Interactions

Somatostatin analogs (antagonize). Otherwise minimal interactions — cleanest side effect profile of all GHSPs.

Reversibility

🟢 Fully reversible — body returns to baseline within days

Research Disclaimer

Almost all data is preclinical (animal or in-vitro). No large-scale randomised controlled human trials are available for most compounds on this catalogue. This information is provided for research reference only.

Storage Requirements

Reconstituted: 2-8°C, 14-21 days

State	Condition	Duration
Lyophilised (sealed)	2–8°C	12-24 months
Reconstituted	2-8C	4–6 weeks

Reconstitution Note

Reconstitute with bacteriostatic water (BAC water). Do not shake vigorously -- swirl gently to dissolve. Inject BAC water slowly down the side of the vial to avoid denaturing the peptide.
