comparing Tren to Anavar (var) is like comparing the patriots to a peewee football team. Tren is the single greatest compound you can run if you know what you are doing.
It makes you hard, strong, fit, vascular, lean, and want to train. It does have some sides but you need to take all precausions and you will be fine. If you have experience trade the Anavar (var) for tren!
