I’ve been on tirzepatide for about 11 months, down 38 lb, lifting twice a week, and my elbows are now the bottleneck. PEG-MGF keeps popping up in peptide discussions as a recovery angle, and mechanically I get why it sounds appealing.
But when I try to read past the hype, I hit a wall: tiny studies, mixed outcomes, and a lot of hand-waving about IGF-1 and long-term safety. In the trials I can find, the sample sizes are small enough that I don’t trust the confidence people put in it. I’m not asking for a protocol or a source.
I’m trying to figure out whether the plausible mechanism outweighs the unknowns, especially for someone already on a GLP-1 and not trying to add more variables. Has anyone here gone down this rabbit hole and come out either more or less convinced? What actually made you decide yes or no?
