Hexarelin
Strongest older GHRP. Faster desensitization than newer compounds; short cycles required.
- Half-life
- 42 min
- Out of system
- ~4 h
- Route
- Subcutaneous
- Level
- Advanced
Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~4 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Hexarelin is used for
- Strongest of the older GHRPs — large GH pulse
- Short, sharp cycles for recovery/strength
How it's typically used
Research range: ~100 mcg subcutaneous daily for short (2–4 week) blocks.
What to watch for
- Fastest desensitization — effects fade quickly; short cycles only
- Raises prolactin/cortisol; possible cardiac effects at high doses
- 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.
