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?
PEG-MGF keeps tempting me, then I read the unknowns

I track elbow pain 0–10 daily and keep a separate weekly tonnage column. My trendline says it correlates with grip-heavy pulling volume (r≈0.68 over 12 weeks), not pressing. Adding 3 sets of rows moved my 7-day pain average from 2.1 to 4.6. So I’d ask: is your elbow pain inner or outer, and does it flare after pulls or pushes? PEG-MGF’s unknowns aside, my log pointed at load sequencing and sleep, not a missing recovery peptide. What does your weekly set count/tonnage look like for pulls vs presses?

I run a cafe too, and my elbows were the first thing to complain—piping bags, milk crates, and tasting spoons add up. Peptides are way outside my lane, but one thing that helped me stop chasing shiny recovery fixes was a dumb 2-week log: elbow pain 1–10 each morning, plus any shift tasks and gym moves from the prior 24h. Turned out my flare-ups tracked with back-to-back days of heavy grip work and tray-carrying, not with my lifting volume. Have you tried separating shift-load from gym-load yet? That might tell you whether it’s a recovery gap or just cumulative elbow use.
