Best IGF-1 providers

Research vendors selling IGF-1, ranked by objective criteria. Research use only — not a purchase recommendation or health advice.

How this ranking works

Providers are ranked by an objective, transparent blend of verification status (20%), our provider trust score (45%), this peptide’s price competitiveness in $/mg (25%), and verified third-party (COA) testing when available (10%) — no editorial opinion or paid placement affects the order.
