per administration
Only animal or lab studies exist — no human study has set an amount.
Quick start
MGF at a glance — the figures, plus how it's commonly run. Reference only, not medical advice.
- Typical dose

- How often
- Every other day
- Where
- Commonly subcutaneous Sites and rotation
- Time to steady level
- ~1 hours — about five half-lives
- Storage
- Dry vial kept cold and dark; a mixed vial in the fridge at 2–8 °C. Details
A research and community reference, not medical advice. Figures are descriptive, vary between sources, and are not a recommendation for use.

Published research contexts for MGF describe 100–200 mcg per administration. Descriptive only, not a recommendation.
The unpegylated splice variant clears within minutes; human pharmacokinetics are not established.
An IGF-1 splice variant (IGF-1Ec) studied in rodent muscle models; no human dose-ranging study exists and the injected figures are community-derived, so no schedule table is shown.
Modelled level — every other day
1× is the peak after a single dose.
- Steady-state peak
- 0.97× single dose
- Time to steady state
- 1hours
- Administrations
- 3.5/ week
