You won't need anything for physical gains, so watch your diet and enjoy the results. For increasedand power, I would highly recommend Citrulline. Maybe look into some noots to round out how good you feel physically.
I imagine you are a little older if you are on TRT, so stinging nettle or a prostate blend with is a good addition also.
I'm 24 actually.
whats the best pre workout out now for endurance, strength? what about post workout?
