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.

Small tetrapeptide, and the MS on the COA confirmed the low molecular weight exactly. ≥99% purity. Perfect for our telomerase cell-culture assays.
Dispatched same day, arrived sealed with legible lot numbers. The batch report was already in the vault before the package landed.
Fair price and a complete certificate. Dissolved instantly. Exactly what I need for repeatable cell work.
Being able to look up the certificate by lot number before ordering is the whole reason we switched. Documentation is impeccable.
Packaging was discreet and protective, labels crisp, and the lot resolved to a real report in the COA vault. Zero complaints.
Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.

Everything checked out against the COA. Shipping took a day longer than expected but arrived well packed.

Third order across two different lots and both COAs line up. Consistency matters more than a headline purity number, and they deliver it.
Ordered the 5-vial bundle — per-vial pricing is fair and the volume discount applied exactly as shown. Smooth checkout.
Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.
Material was as documented, but one outer box arrived a little crushed. Contents were protected so no real harm.
No issues with the material itself. The label print was slightly faint on one vial but still fully legible.
