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.
Lab results
Every lot links to its full Certificate of Analysis from Aegis Bioanalytical Laboratories, an independent ISO/IEC 17025-accredited lab — each with a Report ID you can verify.

Dispatched same day, arrived sealed with legible lot numbers. The batch report was already in the vault before the package landed.

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.
Being able to look up the certificate by lot number before ordering is the whole reason we switched. Documentation is impeccable.
Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.
Third order across two different lots and both COAs line up. Consistency matters more than a headline purity number, and they deliver it.
