MGF (Mechano Growth Factor)
The IGF-1 gene produces multiple isoforms by alternative splicing. IGF-1Ec is upregulated after mechanical muscle loading; the C-terminal E-domain is cleaved from the mature IGF-1 protein and appears to have independent effects on satellite cells. The exact receptor binding of the E-domain is not established; a classical IGF-1R effect is unlikely since mature IGF-1 is responsible. In cell-culture studies, stimulation of myoblast proliferation and differentiation has been observed.
Sermorelin
Synthetic analogue of the first 29 amino acids of human growth-hormone-releasing hormone (GHRH). Stimulates pulsatile endogenous growth-hormone secretion from the pituitary via the GHRH receptor. Very short plasma half-life — pharmacodynamic effect lasts several hours nevertheless.

Frequently asked questions
- What is the difference between MGF (Mechano Growth Factor) and Sermorelin?
- MGF (Mechano Growth Factor) is classified as "Crescita", while Sermorelin is classified as "Crescita". MGF (Mechano Growth Factor): Synthetic peptide corresponding to the C-terminal E-domain of the IGF-1 splice variant IGF-1Ec. Described in preclinical studies as a 'mechano-induced' skeletal muscle repair factor. No marketing approval; clinical use largely confined to the black market. Sermorelin: Synthetic analogue of the first 29 amino acids of human GHRH. Stimulates pulsatile growth-hormone secretion from the pituitary. Formerly FDA-approved as Geref Diagnostic, now withdrawn in many markets — compounding and research use dominate. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, MGF (Mechano Growth Factor) or Sermorelin?
- The highest available evidence level is "Modello animale" for MGF (Mechano Growth Factor) and "RCT sull'uomo" for Sermorelin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of MGF (Mechano Growth Factor) and Sermorelin in Germany and the United States?
- Germania: MGF (Mechano Growth Factor) — Non approvato, Sermorelin — Non approvato. Stati Uniti: MGF (Mechano Growth Factor) — Non approvato, Sermorelin — Solo ricerca. These are factual summaries with source and review date on the individual pages.
