Observed signals

criticalIn our analysis, lot "5-3-45937" appears on 3 different peptides at BioLongevity Labs: bpc-157, bpc-157-tb-500, tb-500. A lot number normally identifies a single manufacturing batch of one compound, so this pattern can indicate recycled lab data — or a vendor reusing one identifier across a multi-product shipment. Flagged from the COAs available to us; vendors may contest this.

Any signals or scores shown are our opinion based on the data available to us.
