- Half-life
- 18 min
- Out of system
- ~2 h
- Route
- Subcutaneous
- Level
- Intermediate
Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~2 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What GHRP-2 is used for
- Strong ghrelin-mimetic GH release
- Supports recovery, sleep, and body composition
How it's typically used
Research range: 100–200 mcg subcutaneous up to 3× daily.
What to watch for
- Raises cortisol and prolactin more than Ipamorelin
- Strong hunger spike; glucose changes
- Avoid with cancer or pituitary issues
About Performance & GH
- What they are
- Growth-hormone secretagogues and related performance compounds. Rather than supplying GH, they push your pituitary to release more of its own in a pulse.
- How they're run
- Subcutaneous injection, most often at night on an empty stomach so the pulse lands with natural sleep-driven GH release.
- What to watch
- Water retention, tingling hands, and hunger swings are the common early signs. Raising GH raises IGF-1 — worth tracking on bloodwork, and a reason to avoid these with any cancer history.
