I think if you're going to run TST you need to keep the dose low and stack it with something.
I haven't gone above 8mg/day since starting and I'm still gaining weight and strength.
I'm not using crazy dosages for the havoc either. I'm going to stay at 30mg for my final week. Why use more if the gains keep coming????
Also, like Trip Dog says if you're using stuff that like TST that is very androgenic you need prostate protection. I swear by the NOW nutrition prostate support soft gels.
Finally, how much water are you drinking? Are you getting enough.
Good luck and keep posting!
