From what I read and understand, the small amounts of HCG (250IU to 500IU) two days each week will keep your boys from shrinking (HCG will maintain testicular form and function while you are shut down) and make your recovery (PTC) faster. Do not try to think more is better. Anything above 500ius per day will cause too much aromatized activity (estrogen levels will go way up). I would start with 250ius twice a week and see if that will prevent from testicular atrophy. If 500ius isn't enough ( and you will know that) I would shoot HCG one or two days more often per week than taking higher doses twice a week. Some take HCG while on the cycle some start 3 weeks into the cycle or during the last 4-3 weeks of the cycle(1000-1500ius a week). Those who take HCG at lower doses thru the cycle seem to recover faster since they managed to maintain testicular activity while being shut down. I would take an AI at low does while taking HCG to keep estrogen levels (elevated by aromatization)in checked. Do not kill all the estrogen in your body as you need it as well to build muscles, keep your joints in shape and .....you want your libido as well don't ya
AIs on the cycle, SERMS save them for PCT. I'd take Aromasin at low does 20-25mg ED or EOD. That should keep estrogen in the safe range BUT everybody is different so you need to keep an eye on sides that high estrogen may cause and have ancillaries ready on hand in a case if you need to combat sides(gyno). So keep in mind, AI will have no effect on direct stimulation where HCG can increase testicular estrogen and that's where tamox comes into play. Any increase in estrogen done by aromatization can be controlled via AI. Once you mixed your HCG it can be refrigerated 30-45 days (more days stored=less potent).
