FAQ
How long does reconstituted peptide last?
Once mixed with bacteriostatic water, peptides remain stable for up to 4 weeks when refrigerated at 2-8°C (36-46°F). Unopened powder can last 1+ year in the freezer. Get our complete Storage & Travel Guide.
Is this peptide legal to purchase?
Peptides sold "for research purposes only" are legal to purchase in the US, but are not FDA-approved for human use outside of specific medical applications. Always consult a healthcare provider before use.

What Is MGF (Mechano Growth Factor)? IGF-1 Splice Variant
MGF is a locally-acting IGF-1 splice variant. The gene-level science is real; the injected-peptide muscle-building claims stay unproven in humans.
comparisonMGF vs PEG-MGF: Half-Life, Evidence & Safety
PEG-MGF claims a 48-72h half-life vs native MGF's minutes. But a 2014 replication found the E-peptide did nothing to muscle cells.
