Personally I like to take my HCG the last 3weeks of the cycle (including the period that the long esters are clearing my system) @ 500iu's eod. Then start the SERM (I prefer torermefine over nolva and clomid) and I use an AI in an inverse taper w/ the SERM. But it's important that it's a STEROIDAL AI like ATD or exemestane, and NOT a non steroidal like arimidex or letro, because steroidal AI's bind irreversibly to aromatase and wont cause an increase in aromatase and subsequent "rebound effect" of increased estrogen when you stop using it.
So in other words I start w/ my highest dose of the SERM and about a quarter of my top dose of the AI, and I bring the AI up each week as I taper the SERM down. This process is drawn out over about 5-6 weeks.
I also like to take OTC test boosters such as fenugreek or tribulus. (Somepeople like long jack too.) Just make sure the otc test booster you use isnt another form of AI. That would be just too much estrogen suppression. When choosing otc supps dont think so much about "brand name". That is, not to say that you shouldnt BUY brand names, it's fine to BUY brand names, but just think "ACTIVE INGEDIENTS". Knowing what common active ingredients are in a product w/ a brand name and reading up on each ingredient is more important IMO. That way you avoid "doubling up" on products w/ some or all of the same ingredients, and who knows? You might find the same ingredient in a bulk powder form for a fraction of the cost.
It never hurts to use other non HPTA suppresive compounds that dont neccesarily contribute to HPTA recovery but help to maintain lean mass and/or prevent fat gain. IE: GH, LR3IGF1, Peg-mgf, insulin (if youre experienced w/ it) possible conservatively dosed T4 (especially if implementing GH)
Hope this gives you some idea's.
