Pros: Extended half-life compared to unmodified MGF, in theory allowing fewer, more practical dosing intervals Mechanism aligns with well-studied endogenous muscle-repair biology (satellite cell activation, IGF-1 pathway) Widely available from research-chemical vendors for lab/research purposes Cons: No FDA approval, no completed human clinical trials, and no regulator-reviewed safety or efficacy data Prohibited in competitive sport under WADA growth-factor rules Product quality and purity vary significantly between unregulated research-chemical suppliers Side Effects: Not well characterized due to the absence of an approved label
