Almost 13 years, so yes. TRT and AAS are the only things that really help with muscle.
How long did it take me to become able to exercise? It’s impossible to say because it’s always been a matter of energy levels at the time, intensity/volume of the exercise, and how badly I had to pay for it afterwards. Things only really improved in the last couple of years, but still not 100% and I continue to experiment with things.
