Couple little problems that are easy to address.
Make sure you mix it with Bacteriostatic Water, NOT the Nacl that usually comes with the amps. Nacl solution is for immediate injection, it supposedly allows the HcG to become inert rapidly. Like, overnight supposedly. But HcG + Bac water is good up to 60 days. So, IMO, ya need Bacteriostatic water if you dont have it.
Add one ml of Bac Water to the HcG amp and suck up .1ml or "10" on the slin pin. Do this for 10 pins. That's 500iu HcG each. Fridge them. Use as needed.
Edit: on the bac water vs NaCl...this is what I think based on research from several boards, but couldnt find any real medical literature on the subject. Id love to be wrong and have NaCl be usable for longer storage. I just dont think it is.
Hope this helps.
