## FAQ

### What is MGF (Mechano Growth Factor) and how does it differ from IGF-1?

MGF (also labeled IGF-1Ec) is a splice variant of IGF-1 produced locally by muscle tissue under mechanical stress. Unlike circulating IGF-1, MGF is studied as an autocrine/paracrine signal acting on nearby cells, particularly muscle satellite cells, in lab models.

### What is PEG-MGF and why do researchers use it?

PEG-MGF is MGF modified by attaching a polyethylene glycol molecule to the peptide chain. This slows enzymatic degradation and extends stability in solution, giving researchers a longer experimental window to study the compound's behavior compared to unmodified MGF.

### How do you reconstitute a lyophilized peptide like MGF for lab use?

Add bacteriostatic water to the freeze-dried powder vial. Working concentration equals mg of peptide divided by mL of water added. Inject water slowly down the vial wall, swirl gently until dissolved — never shake — then label with concentration and date and store per lab protocol.
