A couple years ago, the late Dr Crisler changed his opinion about dosing HCG. The outdated "Crisler protocol" he advocated in 2004 was generally T dosing 1x/week and HCG a couple days before next T injection.
However, he pretty well abandoned weekly T dosing for more frequent smaller doses subQ, and changed his tune to HCG daily: Should Men on Testosterone Test Their Free Estradiol ?
That older protocol is considered extinct, gone the way of the dodo, but I am not surprised to see something similar suggested here again. History repeats itself and old adages die hard.
Some men take Dr Saya's small study showing blood levels of HCG based on dose to mean higher doses are better, but that's not what he actually said in his narrative/interpretation of his results.
So what's the best? The opinions and results are still all over the map for different individuals. Vince likes 500iu 2/week and has done well on this for years. I tried that and had terrible estrogen swings. Now I am using 150iu coadministered with T cyp EOD, but might do even better on less QD.
The way to find out what works for you is to try different things, give each new dosage adjustment ample time, so that you are not chasing your tail. In this regard, I think it's great how Ardoc is approaching it.
To the OP... salmon: I believe your weekly T dose is much too high. It puts your free T much higher than necessary, is prone to drive high hematocrit, and E2. And though there is probably a saturation point in terms of T shutting down LH and the subsequent effect on testes, more T ain't better past that point, and trying to dose enough HCG to make testes feel better while avoiding high E2, is problematic. I've been through something similar myself, and what worked was reducing T, and HCG doses. It took along time to iron out dosages that brought my Free T and E2 into tolerable and beneficial range. And reductions are not easy, in fact dabbling in withdrawal Hell.
