I don't know the time tables off hand but what you reconstitue with plays a role in the life of the peptide. I was perscribed HGH and was given bac sodium chloride to reconstitue with. Each vial lasted me 21 days.
Dat suggests reconstituting peptides with bac water. If thats good enough for him it's good enough for me. I use 2cc of bac water when reconstituting 2mg of a ghrp or ghrh. I think I read that Dat says he tries to use as little water as possible because he has a belief that the less water you use the less degredation the peptides undergo.
