Ive often wondered about toxcitity.I'm not as old as this gentleman but I ate plenty of methyl test and stan back in the early 80s.started in my terns and never did aes or pct.here I am in my 50s.I have low t but so does a lot of guys I work with who don't even lift.I do believe gains are better on smaller doses in the long run.but that's just an opinion if somebody wants to run a 1000 My's a week just remember screwings just ad fun when your old.really ive got it made my insurgence pays for test and viagra.lol
