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.

Dispatched same day, arrived sealed with legible lot numbers. The batch report was already in the vault before the package landed.
Third order across two different lots and both COAs line up. Consistency matters more than a headline purity number, and they deliver it.
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.
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.

COA matched and reconstitution was clean; transit was slower than the estimate this time around.
