I'm not sure at how likely these sides are mate. All meds have their sides. Its definately up to you, basically taking steroids is a risky game full stop. It all depends how badly you want your goals. Personally at this point I'm a clean trainer as I cant be dealing with all the potential sides these drugs cause. The fact is from my point of view I see hundrends of threads from people who are experiencing problems from using steroids or prohormones, often being gyno or some kind of sexual malfunction(often these isssues are from users who had weak PCT with no serms). I see these threads pop up more than I see threads pop up on side effects from using serms. Its all a balancing act i'm affraid, one of which you should never be guided by one mans opinion. The steroids you are using, they are strong gear. I wouldn't personally use them without a solid PCT. I believe the risks of side effects from nolva or clomid are far out weighed by the risks of the steroid sides.
