I decided to not use any nolva or nothing for my pct,I did 12 weeks of propenate and eq and now am 7 weeks into my own pct with paravol and I am surpessed that my sex drive is still great,I guess this product is specially designed to for gear users,anyway the only thing I would recommend is to take 2 before you go to bed and 2 in the morning instead of 1 in the morning and 1 before bed but anyway its a great product check it out,almost 2 months and Im not even close to crashing
