Hey im thinking about doing my first cycle....Im 22 and i have been training now for like 4 years now. I was wondering how a 4 or 6 week cycle of Sustanon 2 50 would work...how would strenght and mass gains be, and what side effects could i expect...and would they be bad? Also with such a short cycle at possible 4 weeks would i need to buy an anti estrogen? would 6-0X0 work?? Thanks...and if anyone here has taken it and can give me info on how often and when to take i would appreciate it...thanks
