Ahah... I finally have a legitimate tricky question... and it only too 719 POSTS!!! One thought of mine is... If I mix it with my regular injection... would the BA and BB in my other compounds be enough to ensure sterility of the injection should I choose to expose my sterile HCG powder so that I can divide it into smaller dosages to be reconstituted seperately?? probably not but just a thought... (i hate thinking)
