What it actually is
GHRP-2 (pralmorelin) is a second-gen GHRP that fires a GH pulse via the ghrelin receptor.
It brings far less appetite than GHRP-6, making it the recomp/cutting choice.
How it’s thought to work
- Ghrelin agonist — GHS-R1a → endogenous GH pulse.
- Milder appetite — much less hunger than GHRP-6.
- GHRH synergy — strong stacked with CJC/Mod-GRF.
- Cortisol/prolactin — dose-dependent, less than GHRP-6.
What the research says
Studied as a diagnostic GH-stimulation agent; some human PK data. Performance dosing is anecdotal. Not approved, WADA-banned.
- Clean GH pulse, minimal hunger.
- Recomp / cutting favourite.
- Stacks 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); higher only when stacked |
| Frequency | 2–3× daily |
| Route | SubQ (IM also used) |
| Cycle | 8–12 wks on, ~4 off to avoid desensitization |
| Community tip | GHRP-2 for cutting, GHRP-6 for bulking; run with CJC/Mod-GRF |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Cutting / recomp | 100 mcg 2–3×/day fasted |
| GH pulse | stacked with CJC-1295/Mod-GRF |
| Sleep / recovery | a pre-bed dose |
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 fasted, 2–3×/day; wait 20–30 min to eat. Commonly co-drawn with CJC-1295/Mod-GRF in the same shot. Refrigerate reconstituted.
Stacks it appears in
- GH pulse combo — GHRP-2 + CJC-1295 — the cleaner, cutting version of the pulse.
