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.

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.

Third order across two different lots and both COAs line up. Consistency matters more than a headline purity number, and they deliver it.
Being able to look up the certificate by lot number before ordering is the whole reason we switched. Documentation is impeccable.

No problem with the vial or its documentation, but the carrier held my package longer than the quoted window.
Ordered the 5-vial bundle — per-vial pricing is fair and the volume discount applied exactly as shown. Smooth checkout.

Everything checked out against the COA. Shipping took a day longer than expected but arrived well packed.
COA matched and reconstitution was clean; transit was slower than the estimate this time around.

Lyophilized cake dissolved fully in bacteriostatic water with no cloudiness or residue. Net peptide content on the COA let me hit exact working concentrations.
