GHRP-6 Dosage Chart
GHRP-6 is a hexapeptide ghrelin mimetic (GHS-R1a agonist) studied as a growth-hormone secretagogue. Its signature is strong, ghrelin-like appetite stimulation, which separates it from cleaner secretagogues like ipamorelin. Research protocols cluster at about 100mcg per dose, timed away from food, and it is most often paired with a GHRH analog (CJC-1295 or Mod GRF 1-29) for synergistic GH release.

Dosage Protocols
Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.
Protocol 1
Standard Research Protocol
Dose
100mcg subcutaneous, 1-3x daily
Duration
8-12 week blocks
About 100mcg is the commonly cited saturating dose; more per injection mostly adds appetite and cortisol rather than GH. Timed on an empty stomach, since food (especially carbohydrate and fat) blunts the GH response. A pre-bed dose stacks on the natural nocturnal GH pulse.
Protocol 2
GHRH Synergy Stack
Dose
100mcg GHRP-6 + 100mcg CJC-1295 (no-DAC / Mod GRF 1-29) per dose
Duration
Matched to the GHRP-6 block
GHRPs and GHRH analogs act on separate receptors and release more GH together than either alone (Bowers et al. 1990). The two short-acting peptides are drawn into one syringe and dosed together, 1-3x daily.
Protocol 3
Appetite / Recovery Research
Dose
100mcg subcutaneous, single dose
Duration
As studied
GHRP-6 drives the strongest hunger response of the common GHRPs, which is why it appears in appetite, cachexia, and feeding-behavior models rather than lean-out protocols.

Handling Notes
Lyophilized: -20°C long-term, 2-8°C short-term. Reconstituted with bacteriostatic water: refrigerate at 2-8°C and use within about 21-28 days. Swirl gently, never shake, and do not freeze the reconstituted solution.
Research Considerations
Cautions
- Appetite stimulation is intense and reliable: a feature for cachexia or bulking research, a liability for lean-out work.
- Unlike ipamorelin, GHRP-6 raises cortisol and prolactin, so it is a less selective secretagogue.
- Water retention and transient rises in blood glucose can occur, consistent with elevated GH and IGF-1.
- GHRP-6 is a research compound, not an approved therapy. There are no established human efficacy doses, and quality varies sharply between suppliers.
