Math is perfect, dosing is okay.
Timing is consistent with some ideologies on hCG but not my own. My thinking is that, because hCG is suppressive to the body's own LH it makes no sense to take it during PCT when the goal is to get the body back on track. The function of hCG is to make sure the testes continue to respond to LH. So..... for a 16 week cycle, lets say, I'd take hCG weeks 3-8 and wks. 10-15. This way the testes don't get desensitized to the hCG, don't atrophy to the point where they stop responding to LH, and the body's own LH is not suppressed during the recovery period.
I mean the way you have it laid out is not terrible. By jump starting the testes functioning early you might aid recovery and you have a few weeks to kill while the sust esters clear the body so there are pros and cons. How long is the cycle going to be and what else do you have planned for PCT? I like sust, it is my favorite actually, but I always go over kill on PCT with it. Just wondering what you have in store?
