Peptide harm reduction applies harm-reduction principles — reducing harm among people engaged in a practice, without requiring that they stop — to the situation of people obtaining peptides outside regulated supply.[1]

The uncertainties are specific and documented elsewhere on this wiki: identity, which a purity figure does not establish; content, which determines how much active substance a vial holds; sterility, which a research-chemical powder does not have; and provenance, which determines whether any document attaches to the material at all.[2]

What the uncertainties are

[edit]
UncertaintyResolved byCommonly reported?
IdentityMass spectrometry confirmationSometimes
PurityNamed chromatographic methodUsually
ContentPeptide content, water, counterionRarely
Fill massGravimetric checkRarely
SterilitySterility testing; not applicable to research powdersNo
EndotoxinBacterial endotoxin testRarely
ProvenanceLot traceability recordsVariable

The row that matters most and is reported least is content. Without it the mass of peptide in a vial is unknown, and every downstream quantity — concentration after reconstitution, volume drawn, exposure — inherits that unknown.[2]
