Ok, sooo, Ive been looking on some websites for HCG. I keep seeing it in ampules at various quantities. 1500 and 5000 Iu's seem to be most common. Arent ampules single use only? If I want to do 500 iu/day and I have a 5000 iu amp will the rest keep for the next injects? Is there a way to reseal the amp? I know, F'n noob. My last bottle was a 10 ml with rubber stopper so that was easy. Am I missing something? Ok now stop laughing and give me as non-sarcastic of an answer as possible. thanks guys.
