Strongly considering retatrutide for a recomp goal given the trial numbers and the string of positive reports I've come across. Still worried about muscle wasting though. Spent a lot of time digging into the underlying science (I get the three mechanisms at least), and it does seem to beat other GLPs on lean mass retention, but separating solid science from confident-sounding anecdotes has been rough.
One claim floating around is that reta doesn't mix well with strict low-carbohydrate eating, maybe dangerously so, though I've never seen that backed by anything beyond bro science. Another insists you have to add a specific peptide on top or muscle loss happens regardless of protein and lifting. Not interested in chasing that setup.
Wondering if anyone can point toward genuinely science-based information specific to reta covering diet macros and what actually helps hold onto lean mass while cutting fat. Barring that, I'd take solid anecdotal evidence too, long term, consistent, accurately measured, showing what has actually worked.
