Good to know
No slogans, no “trust us.” Here is the exact path every PepBiotics vial takes before its lot number ever reaches your label.
Solid-phase synthesis, then lyophilized to a stable powder. Each production run becomes a single traceable lot.
Reverse-phase HPLC quantifies purity and resolves impurities — the headline percentage on every certificate.
ESI mass spectrometry confirms the molecular weight matches the target sequence. No guessing what's in the vial.

Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.
No issues with the material itself. The label print was slightly faint on one vial but still fully legible.
Material was as documented, but one outer box arrived a little crushed. Contents were protected so no real harm.
Packaging was discreet and protective, labels crisp, and the lot resolved to a real report in the COA vault. Zero complaints.
Ordered the 5-vial bundle — per-vial pricing is fair and the volume discount applied exactly as shown. Smooth checkout.
Ran our own analytical HPLC on the lot and it agreed with the published COA within tolerance. Identity confirmed by MS. This is what a research supplier should be.
Product was fine and matched the COA, but this shipment was noticeably slower than my previous orders.
Being able to look up the certificate by lot number before ordering is the whole reason we switched. Documentation is impeccable.
