How a single dose clears, assuming first-order elimination. The half-life is the biggest driver of how often you dose — start a cycle to see your own cumulative concentration curve.

Overview

A potent GHRP and ghrelin-receptor agonist. Strong GH release but prone to receptor desensitization with continuous use.

Mechanism of action

Binds GHS-R1a; also shows cardioprotective signaling. Tolerance builds, so it is usually pulsed.

Typical protocol

100–200 mcg subQ up to 3× daily in short cycles to limit desensitization.

Storage

Reconstituted: refrigerated, ~30 days.
