I prefer clomid over nolva and I run adex, proviron, and HCG during my cycles. I always keep Nolva on hand just incase of a gyno breakout. Some guys run it along side a cycle, and some only use it for PCT. Both are correct methods...and much depends on your cycle. Lots of guys who stack and train with heavy doses, use BOTH nolva and clomid for PCT. 90% of the time clomid is all I need for post. Nolva gave me post cycle acne, so I try not to touch the stuff.
