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.

Material was as documented, but one outer box arrived a little crushed. Contents were protected so no real harm.
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.
Lyophilized cake dissolved fully in bacteriostatic water with no cloudiness or residue. Net peptide content on the COA let me hit exact working concentrations.
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.

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.

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