What can HPLC not tell you?
Threads about chromatography results often assume a single number settles quality, while others point out the limits of what any one assay establishes.
Where this comes from
Summarised from public peptide discussions. Not posted by PEPTD members, and not medical evidence. Observed in public forum threads. PEPTD summarises the recurring theme — it does not republish anyone's post, profile or identity.
Community experience is anecdotal and is not medical advice. PEPTD does not convert discussion into recommended doses or protocols. Published research and regulatory sources are shown separately from public discussion.
Certificates of analysis are widely requested but far less widely understood. Public discussion repeatedly conflates identity, purity and sterility, which are different questions.
