HCG, temporarily stimulates your leyding cells, your testosteone goes up and your estrogen goes through the roof (not like wth regular LH), thats it, that's all it does. But alot of people use it in the belief that it helps to restore their HPTA, I don't know why. MAybea they are right, I don't think so. Many different ideas out there, no AMA or FDA monitoring pannel. But this is a different thread.
