MGF is the IGF-1Ec splice variant expressed by skeletal muscle after mechanical loading or damage. The literature is largely molecular biology and rodent muscle work examining satellite cell activation; the human evidence base is observational expression data rather than administration studies.

Every figure on this page is a range reported in published literature or in a publicly documented study protocol. It is a record of what researchers used, not a recommendation, a therapeutic protocol, or advice. Peptide Intel Hub is an independent publication, sells nothing, and describes these compounds as in-vitro research reagents only.
Each row below describes one body of work. The model and population are part of the figure — a rodent per-kilogram quantity and a human trial quantity are not comparable.
Effects reported are local to the injected muscle in most designs.
Culture concentrations are not administration quantities.
The same arithmetic for every vial size MGF is supplied in, using a fixed 3 ml of bacteriostatic water. One unit on a U-100 insulin syringe is 0.01 ml, so the unit column below is simply the volume that carries the reported amount. Educational arithmetic only — not instructions, and not medical advice.
MGF · 3 ml bacteriostatic water
| Vial size | Concentration | Per 1 unit |
|---|---|---|
| 2 mg | 0.67 mg/ml | 7 mcg |
No single reported amount applies to this compound, so only the concentration and the value of one unit are shown. Only the vial sizes this compound is actually supplied in are shown, and every figure assumes exactly 3 ml of bacteriostatic water. For any other volume, use the reconstitution calculator.
Supplied as a 2 mg lyophilised vial. In 3 ml of bacteriostatic water that gives 0.67 mg/ml, so one U-100 unit carries about 6.7 mcg.

Anything circulating online about quantities is anecdote rather than evidence, and this page will not reproduce it.

Peptide Intel Hub is an independent publication and has no affiliation, ownership or commercial relationship with the suppliers listed. We sell nothing and take no payments — links are editorial references only.
Peptide Intel Hub is an independent educational publication. We are not affiliated with, owned by, or the same company as Regena Peptides and Regena.app (regena-peptides.com / regena.app). We do not sell, supply, ship or take payment for any compound. Because readers regularly ask where compounds discussed in published studies can be sourced for laboratory work, we list Regena Peptides and Regena.app as suppliers we have verified and trust — every batch is released with a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity). Outbound links are marked nofollow/sponsored and are provided to help readers, not to sell.
