dude, my doc, who juices, told me to hit it at the first half life of your a.as, so if i'm doin test testosterone cypionate(500 mg/wk), and my last injection in on friday, then I'd start two weeks later on friday(it's actually 12 days, but for simplicity i'm doin it on friday). I'd hit the HCG - human chorionic gonadotropin - at 3-5000 ius on friday, then 3 days later hit 2-2500 ius(repeat 3 times- 4@2-2500), then one last inject @ 1250. start clomid with first inject, do clomid 100 mg ed for 3 wks, then drop to 50 mg/wk for 2 wks., this is from his book(anabolics 2004). you can reduce or increase as necessary, this is just a recommended guideline he gave me. For your cycle, you probably only need the HCG - human chorionic gonadotropin - , start it about 2 weeks after your last pin. again, this is from my doc, and it's assuming you're coming off for a while, if you're going back on in a month or three, just use the HCG - human chorionic gonadotropin - only. just my 2
