i figured that i would ask you guys since i've never used hcg. but i have a buddy that has been on 500mg of cyp a week for about 16 weeks and is finishing his cycle. he wants to start hcg therapy but doesn't know how much to use. currently, he only has one kit with 2- 2,000iu. amps. so, how much would he need and when should he take it. thanks guys.
