Questions about storing peptides

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.

Those earlier comments seem right to me anyway.

I'm testing hgh from an unknown source that has a US location. I sent two vials to a lab, one kept frozen for three weeks and the other kept at room temperature. It cost a bit extra to include the frozen vial. I should have the results next week. I've always wondered about this.

I'd appreciate hearing how everything turns out.

Has anyone used a certain testing service? Their site mentioned fast two-day turnaround but they received my samples last Thursday and I'm not getting replies. Can anyone suggest a reliable testing company in the US?

Got a quick question to tack onto this discussion. Preparing for my first collective assessment and it's got me pumped. I signed up to provide a sample initially. But then I recalled that the kits arrived back in mid August and immediately went into a sealed flask along with some drying agents before being stored in the icebox. They've stayed there the whole time. I'm sure the material holds up over long periods. Still after two months in the cold I'm unsure if it's still good enough to submit for checking. It would suck to get rejected during the mailing phase and end up squandering funds along with the group's efforts.
