Frequently asked

How long does GHRP-6 stay in your system?

With a half-life of ≈ 15–30 min, roughly 97% of a single GHRP-6 dose is cleared after five half-lives — about 0.1 days. Repeated dosing accumulates and takes correspondingly longer to clear.

What does a ≈ 15–30 min half-life mean in practice?

Every 15–30 min, the remaining amount halves: 100% → 50% → 25% → 12.5%, and so on. The curve above plots exactly this decay for a single dose.

Where does this GHRP-6 half-life number come from?

Bowers (J Clin Endocrinol Metab 1990, PMID 2108187); cleared within ~1 h. We cite a primary source for every half-life we publish and version every change.
