Lyophilized Powder GH/Pep Volume

[ASAPBlocky]

Im curious how many people get RC/UGL grade peptides or GH and receive a vial with next to no powder in it? It seems most vials are around 2mg but the amount of powder varries greatly, would the active compound vary in volume that much?

The white powder in peptide vials consists in large part of so called excipients that are intended to increase the stability of the hormone. The choice of excipient and the amount used vary from producer to producer. For example, Omnitrope powder contains " glycine, disodium hydrogen phosphate heptahydrate, sodium dihydrogen phosphate dihydrate", whereas Genotropin powder contains " Glycine (E640), Sodium dihydrogen phosphate anhydrous (E339), Disodium phosphate anhydrous (E339), Mannitol (E421)".

We know that some of the more established GH products are quite stable (as assessed by HPLC analysis), so the excipients used must be appropriate. These tend to have standard amounts of powder in the vial.

If you receive a vial with very little powder in it, then the amount of excipients is likely insufficient and the peptide in the vial will be rather unstable and will have lost much potency through degradation and protein aggregation by the time you inject it.

I figured as much, thanks for the detailed write up
