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.

Material was as documented, but one outer box arrived a little crushed. Contents were protected so no real harm.
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.

Ordered the 5-vial bundle — per-vial pricing is fair and the volume discount applied exactly as shown. Smooth checkout.

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

No issues with the material itself. The label print was slightly faint on one vial but still fully legible.

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