I have taken blue/red cap generics from my over seas provider in the past. I took 10iu per day and just looked for normal sides like hands numb, ect but felt nothing. I know there is a great chance that there is little to no real product in the vials but want to run blood tests on the next ones to see. I have read about blood hg and igf-1 test that may work for this but have no idea which one is better or why. I have run pharma grade Jins in the past so really had no need to worry and this whole testing thing, it is all new 2 me. Is a base line test needed to see changes? Please dont respond with preg test, boiling, ect. I want lab test with numbers I can look at. If you have any knowledge about this please respond! Thanks guys
