It's not a magic pill at all.
You still have to eat right and workout or you won't get much benefit
You don't get on it and just grow muscle.
I know a few guys who were fat and got on it and a year later they are still fat.
Very simplistic terms..Diet, training and recovery are what's needed for muscle growth
TRT helps with recovery..MPS
Muscle protein synthesis
I had late afternoon bouts of fatigue and problems concentrating on work projects
I never really had low drive
I did have trouble recovering from my training and it has helped with that.
That's not an issue for me. I run 4 to 5 days a week.. before I strained my shoulder and neck weight lifting 3 to 5 days a week. I'm already busting my ass and my diet is pretty strict with little cheating. I don't drink, I don't smoke etc.
