You could probably take 150-200 3x/week and be fine. Only labwork will tell. So, anybody that says take xxxx per inject doesn't have a clue.
Most people say to take way more hCG than necessary, that includes most idiot doctors who really don't know **** except when dealing with pregnant woman.
The only way to know if start with a dose like above, after a week or two, do some labs to see where Test/E2 is. Go from there.
Also, you can reconstitute and freeze hCG. It won't effect the efficacy of it over several months frozen. I can get about 3 months of syringes/dosages almost with a 10,000iu vial.
Just take a bunch of 31cc syringes, fill them up to like 125mcg each, freeze them. Take it out, 5 minutes later after a shower in the morning, thawed and inject, 3x/week I do this. I also take Tcyp, so my hCG dose is a bit lower, but anything more causes aromatase in me personally.
I've also done 100mcg 3x/week, and was around 450TT on labs, no Tcyp, just mono...so there is some proof that with two good working nuts, you can produce a descent amount of test with even smaller dosages..
