It would seem wise to potentially add a low dosed anabolic androgenic steroid like Anavar (Oxandrolone) [1] during a course of Ozempic. This would help keep skeletal muscle in tact during a calorie deficient period. A low dose wouldn't be expected to cause much, if any, side effects. But it's something that would be best put through rigorous studies.
But bodybuilders have been using tricks like these for decades (obviously at much more ridiculously high amounts) that work quite successfully for this exact purpose.
I have done exactly this. I stack semaglutide with ~ 1 ml testosterone and .35 ml of anavar weekly. I’ve transitioned out of regularly competing in powerlifting to running and yoga everyday. 47lbs down in 5 months and havent felt this good since college.
There are non-steroidal OTC supplements that are specifically anti-catabolic instead of anabolic like HMB[1], a metabolite of the amino acid leucine, and also widely used in the fitness community. Personally I have no idea which is preferable though, or whether anti-catabolism is something actually positive, as we know the importance of autophagy of senescent cells for longevity. Most of the literature I read suggests the less growth signalling, the better longevity, with the only exception being the frail elderly.
