Yesterday I took my first injection of Cyp and plan on taking 500mg for 12 weeks. I have Nolvadex for PCT but am unsure of the dosage/length of use/and when to start. Also, alot of the posts that I have been reading regarding "first cycles" - written by those that seem knowledgable - all say that HCG should be taken during the cycle. I am wondering if that is neccessary for my cycle.
