Sorry guys I have more questions. First is can I just leave my unmixed vials in my night stand or do they need to be refrigerated? Second is how unstable is the hgh....I have been squitring my ba water right onto it when I mix it but now people are telling me im making the whole vial bad by doing it. Also my hgh is called gentropin.....what kind of experience have you guys had with this one? Im starting at 2 and working up to 8 ius a day over the next few months than ill stay there as long as I can.
