Searched first, found bits of this scattered across old threads, so figured I’d start a proper one.
Three new sellers appeared in the last six weeks with suspiciously similar site templates.
Prices moved noticeably this month across several vendors at once, which usually means something upstream changed.
Interested in actual experiences, and please say when you’re guessing.
No replies yet. Be the first to add one.
Worth adding that this only holds for lyophilised product.
imo people way overthink this compared to just sleeping properly
Reversed-phase HPLC with UV detection at 214nm is the standard here because the peptide bond absorbs there. If a vendor reports purity without stating the method or wavelength, the number is not comparable to anything.
Was just about to ask this.
If you want to check this yourself, ask the vendor which laboratory issued the certificate, then email that laboratory with the report number. Most will confirm or deny. The ones that go quiet tell you something.

Three anecdotes is not data. It is not nothing either, but it is not data.
