1) No. 2) No, the vials are sealed or vacuum sealed and already contain 1-4 percent moisture, similar to flour at around 14 percent. 3) I don't know. 4) Some peptides are currently being tested for freeze-thaw effects and so far show only slight degradation or results within the margin of error. HGH on the other hand does not hold up well.
When I started getting peptides I had no desiccant packs for the containers but I have them now. My questions are these. First, does taking the vials out of the freezer now and then for a few minutes to add or remove others cause any damage to the dry powder? Second, since I skipped the desiccant packs at the beginning, could moisture have entered the vials and started breaking down the peptides? Third, someone told me never to freeze GH powder at all because even one freeze and thaw ruins it. Is that accurate? Fourth, is a single freeze-thaw cycle okay or do multiple cycles cause the damage? I may be overthinking this but I spent a lot on these and want to run a serious cycle after the holidays without ruining anything.
