I have a 5000 I.U. bottle of HCG that comes with an amp of 1ml solution. I have 100 unit slin pins and I will take 250 I.U.s 2 times per week. I calculated that to get 250 I.U.s, I would draw up 2.5 units of HCG. Is this formula correct? I believe it is based on Austinites article. Feedback would be appreciated!
