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.
This product’s first production batch is at the lab now — results are published here before it ships.

Being able to look up the certificate by lot number before ordering is the whole reason we switched. Documentation is impeccable.

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.
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.
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.

COA matched and reconstitution was clean; transit was slower than the estimate this time around.
Dispatched same day, arrived sealed with legible lot numbers. The batch report was already in the vault before the package landed.
