GHRP-2 vs GHRP-6
Compare the research, key figures and safety notes.
How they differ
Two of the earliest growth-hormone release peptides, working the same switch. GHRP-2 is the stronger trigger and is used in Japan as a single-dose gland test; GHRP-6 brings on more hunger. Both clear in about twenty minutes, so both act as short bursts rather than building up.

These amounts and schedules are figures discussed in research and community reports, shared for learning — not a recommendation and not medical advice. A step-by-step dosing schedule exists only where a human trial backs it; the evidence tier tells you which.
Decay curves, overlaid
Each line is scaled to that compound's own first dose, so the chart shows how each one builds up over time — not how the compounds' doses compare to one another, which these different molecules share no common unit for.
