Mechano Growth Factor (MGF)

Muscle-damage-responsive IGF-1 splice variant. Very short half-life, post-workout timing critical.

Half-life
6 min
Out of system
~1 h
Route
Subcutaneous
Level
Advanced

Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~1 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.

What Mechano Growth Factor (MGF) is used for

  • Muscle-damage-responsive IGF-1 splice variant
  • Used post-workout for local repair signaling

How it's typically used

Research range: ~200 mcg subcutaneous post-workout (local).

What to watch for

  • Very short half-life — timing-sensitive, much overstated
  • Theoretical cancer-growth concern
  • Research-only; minimal human data

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.
