GHRP-2 dose guide

A peptide dosage chart, one peptide at a time: its dose range, how often it’s taken, a typical run and the units on your syringe. All 69 peptides in the PepVault library.

A community reference, not medical advice. Each range is what has been studied or is commonly run, never a dose for you.

GHRP-2 dosage

A potent growth hormone secretagogue: more potent than Ipamorelin but less selective, so along with GH and IGF-1 it also raises cortisol and prolactin. Commonly reported: noticeable hunger after a dose (milder than GHRP-6), a flush or head rush after injecting, and water retention or tingling hands with ongoing use. Approved in Japan only as a diagnostic test for GH deficiency.

Dose range
100–300 mcg (research range). Studied in research — not a recommendation.
How often
2–3× daily: 2–3x daily
A typical run
8–12 weeks. Desensitisation is less rapid than with GHRP-6 or Hexarelin (no head-to-head data), but cycles are still recommended.
How it’s taken
Vial: SubQ injection
Evidence
Moderate: Animal studies + some human data
Half-life
~30 min

GHRP-2 on your syringe

With a 5 mg vial and 2 mL of water (2.5 mg in every mL), on a 0.3 mL (30-unit) U-100 insulin syringe: the low end, 100 mcg, is 4 units; and the high end, 300 mcg, is 12 units. 50 doses in the vial at the low end. All U-100: 100 units to the mL. A U-40 syringe reads differently.
