Don't waste your time and money on HCG on cycle. Cut your TREN out 1-2 weeks early(Ace /Enanthate- 1wk, Hex.-2wks) continue with the Test for the last 2 weeks. Continue the AI throughout PCT, Begin HCG a week after the last pin of Test. Begin 500iu of HCG, EOD for the next 2 weeks. Begin Clomid at 50 mg for the next 4 weeks. End PCT. NOTE: Remember Sustanon takes the longest to get out of your body (3 weeks) Don't waste the Clomid if there's still hormones left in your body! Also, No Nolvadex - it can elevate prolactin levels which Tren has already done. If you're taking caber/dostinex/prami,etc. then the Nolva/Clomid combo is ok, so continue it at .25mg every 3 days . But for $$$ sake , keep it simple, Caber/Dostinex is expensive, Also study the Esters of the gear you run and take what you need, don't play with your body and overload theGear/ PCT. Lastly, I strongly recommend taking only Pharmaceutical Grade PCT gear.
