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.
In the literature
Studied pathways reported in preclinical and in-vitro research — not health claims or intended uses.
Used in research on growth-hormone-releasing-hormone and secretagogue signaling and pulsatile GH secretion in model systems.
Investigated for effects on IGF-1 signaling and downstream growth pathways in cell and animal models.
All products are intended strictly for laboratory research use only (RUO). They are not intended for human or veterinary use, and are not drugs, foods, cosmetics, or supplements. Not for diagnostic, therapeutic, or consumptive use of any kind.

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.

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

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.

Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.
Third order across two different lots and both COAs line up. Consistency matters more than a headline purity number, and they deliver it.
