It depends on how you react. Personally I can fuck for hours on tren only, but I have difficulty achieving an orgasim while on it without test. I've found that most of the side effects can be alieviated by stacking with a milder anabolic (part of the reason for this is explained in the "tren winstrol synergy thread" on the board right now) or completely alleviated with the use of a low dose of winstrol. YOu way wish to stack in a little winstrol (10 mg a day) if you plan on using it without test, and it will complement your cutting stack quit well. Limit yourself to 50 mcg of t3 a day, at the peak of its usage (remember to taper it up and down), or you will loss lbm. Good luck.
