Carl read the papersWhat it actually is
GHRP-6 is a first-gen growth-hormone-releasing peptide that triggers a GH pulse by mimicking ghrelin.
Its signature is appetite — the strongest hunger of any GHRP, which is why it’s the bulking pick.
How it’s thought to work
- Ghrelin receptor — binds GHS-R1a to fire an endogenous GH pulse.
- Appetite — strong ghrelin-like hunger 15–30 min post-shot.
- GHRH synergy — stacks with CJC-1295/Mod-GRF for a bigger pulse.
- Cortisol/prolactin — creep up at higher doses.
What the research says
Older peptide with early GH-response data but no modern clinical use; not approved, WADA-banned. Community dosing is practitioner lore, not trials.
- GH pulse for recovery/body comp.
- Appetite boost (bulking).
- Almost always stacked with a GHRH.
Reported protocols
These are the doses the peptide community actually reports running (Reddit & forums), alongside published research — logged for education, not as a recommendation to use.
| Parameter | Commonly reported range |
|---|---|
| Community dose | 100 mcg per shot (saturation dose) |
| Frequency | 1–3× daily (AM fasted, post-workout, pre-bed) |
| Route | SubQ (IM also used) |
| Cycle | 8–12 wks, or continuous with deloads |
| Community tip | 100 mcg saturates the receptor — split into more daily doses, don’t mega-dose one |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Bulking / appetite | 100 mcg 2–3×/day fasted, with a GHRH |
| GH pulse | stacked with CJC-1295/Mod-GRF |
| Recovery / sleep | a pre-bed dose is common |
Mixing it (reconstitution)
Freeze-dried peptides must be reconstituted with bacteriostatic water before they can be measured. Carl’s calculator turns “mg in the vial + ml of water + target dose” into “units on the syringe” — and tells you how long the vial lasts.

Injection & handling
SubQ (or IM), 100 mcg per shot, on an empty stomach — wait 20–30 min before eating so food doesn’t blunt the pulse. Rotate sites; refrigerate reconstituted, use within ~28 days.
Stacks it appears in
- GH pulse combo — GHRP-6 + CJC-1295 — GHRP + GHRH for a bigger release.
- Bulking — paired with a GHRH when the appetite boost is wanted.
