I've read a few threads about HGH storage on various forums. Consensus seems to be that it must be stored in a cool place (ie fridge) in its powder and reconstituted forms. That part seems pretty clear, However, I've read a few mixed statements on how long it stays good for. Some said it only stays good for 72 hours once mixed, whereas others said it'll be fine for up to two weeks. As a powder, some said it lasts 3/4 months and others said it lasts 2 years. I'd appreciate any clarification and personal experiences. Thanks!
