Which Supp's While on T Therapy

Just started Doc perscribed T therapy,wondering what supp’s to do besides whey/beef protein, multi vit,fish oil/d3. wondering about bcaa’s .

creatine

Just curious - why do you think you suddenly need to supplement now that you are on TRT?

Been on supplements for years,just wandering if any are better or just of little use while on Try. Not a bodybuilder more of cross fit style workouts.
