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.
Studied for effects on neurotrophic (BDNF/NGF) and neuromodulatory pathways in preclinical cognition models.
Investigated in cell-culture and animal-aging models for effects on cellular-senescence and longevity-associated pathways.
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.
Dispatched same day, arrived sealed with legible lot numbers. The batch report was already in the vault before the package landed.

Packaging was discreet and protective, labels crisp, and the lot resolved to a real report in the COA vault. Zero complaints.
Lyophilized cake dissolved fully in bacteriostatic water with no cloudiness or residue. Net peptide content on the COA let me hit exact working concentrations.

Purity and identity were on point. Only nitpick is the vial is a touch small for larger diluent volumes — minor.
