Growth-hormone-releasing peptide that boosts GH and appetite; commonly stacked with a GHRH like CJC-1295.
GHRP-2 (pralmorelin) is a growth-hormone-releasing peptide that strongly stimulates the pituitary to release GH, while also acting like ghrelin to increase appetite. It is potent and reliable enough that in Japan it is used as a diagnostic agent for GH deficiency.
Compared with Ipamorelin it gives a bigger GH pulse, but with less selectivity: it can also raise cortisol, prolactin and hunger, particularly at higher doses. For many users the appetite boost is a feature (bulking) rather than a bug.
It is most effective stacked with a GHRH such as CJC-1295, where the two combine for a markedly larger and more natural GH release than either alone.
Robust GH stimulation supporting recovery and body composition.
Well-documented potent GH release; used clinically as a diagnostic
Increases hunger via ghrelin-like action — useful for bulking or poor appetite.
Demonstrated in human studies (increased food intake)
Supports lean mass and recovery when stacked and trained around.
Mechanistically sound; gradual aesthetic effects
We rate every peptide honestly across four dimensions — and tell you what it's not.
Mostly preclinical (animal/in-vitro) evidence with a clear mechanism. Human effects are largely anecdotal.
Men in a building phase who want strong GH release and don't mind (or want) the appetite boost
Stack with CJC-1295. Higher doses raise cortisol/prolactin — more is not better. Time doses around meals.
Women using GH peptides who can tolerate increased appetite
Appetite stimulation can be pronounced; limited female-specific data. Avoid in pregnancy.
Used by women; may stimulate appetite. Limited female-specific data.

Do not use with active cancer.
Can raise cortisol and prolactin at higher doses.
Stack with a GHRH for a stronger, more natural GH pulse.
The effects most commonly reported with GHRP-2, when they tend to show up, and how to manage them.
Often eases as you adjust; lower the dose if bothersome.
A carpal-tunnel-like effect from fluid shifts — reduce dose if it persists.
Plan meals around dosing; more pronounced with GHRP-6/GHRP-2.
Dose before bed; lower the dose if daytime grogginess occurs.
Monitor fasting glucose and HbA1c; especially relevant if pre-diabetic.
