Summary
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist (GHSR-1a). It stimulates GH release with high selectivity — minimal effect on cortisol or prolactin compared to other GHRPs. It is commonly stacked with CJC-1295 (no DAC) for a synergistic GH pulse.
Ipamorelin is the 'clean' GH releaser. Older growth hormone-releasing peptides (GHRP-2, GHRP-6) also spiked cortisol and prolactin as side effects, which you don't want. Ipamorelin triggers a GH pulse with very little of that spillover. It works through the ghrelin receptor — a different receptor than CJC — so pairing them gives a bigger combined pulse than either alone.
Mechanism of Action↓
Binds and activates the ghrelin receptor (GHSR-1a) on pituitary somatotrophs. The pentapeptide structure confers selectivity for GH release without significant off-target ACTH/cortisol or prolactin stimulation. Synergy with GHRH agonists (CJC-1295) is mediated by different receptor systems converging on cAMP/IP3 signaling in somatotrophs.
Half-life: ~2 hours
Research Dosing Ranges↓
100–300 µg per injection
2–3× daily; frequently paired with CJC-1295 no DAC
Pre-sleep injection most common. Empty stomach optimizes GH response.
Reconstitution Guidance↓
BAC water: 3 mL
Resulting concentration: 1.67 mg/mL (for 5 mg vial)
Add 3 mL BAC water to 5 mg vial → 1.67 mg/mL. 200 µg dose = 120 µL = ~12 units U-100.
Storage & Stability↓
Refrigerate. Use reconstituted solution within 28 days.
Known Side Effects / Contraindications↓
Water retention, increased appetite (ghrelin agonism), flushing, lightheadedness. Fewer cortisol/prolactin effects than GHRP-2 or GHRP-6.

Concentration: 5 mg ÷ 3 mL = 1.67 mg/mL (1667 µg/mL)
Dose needed: 200 µg = 0.2000 mg
Volume per dose: 0.2000 mg ÷ 1.67 mg/mL = 0.1200 mL
On U-100 syringe: 120.0 µL = 12.0 units
Total doses in vial: 5 mg ÷ 0.2000 mg = 25.0 doses
