Why researchers choose OXpeptides
Every peptide is lyophilized at >99% purity, synthesized under GMP conditions and shipped with a certificate of analysis on request — exactly what research protocols call for.
What are research peptides?
Research peptides are short chains of amino acids synthesized for use in laboratory research models — in-vitro assays, preclinical animal studies, and mechanistic investigations. They are supplied as a lyophilized (freeze-dried) powder in sealed glass vials and reconstituted with bacteriostatic water before use. Our catalog spans metabolic peptides (Retatrutide), regenerative peptides (BPC-157, TB-500), copper peptides (GHK-Cu, AHK-Cu), mitochondrial peptides (MOTS-c, NAD+) and regulatory peptides (Selank, Semax).
How we test every batch
Each batch is released with a certificate of analysis covering identity (mass spectrometry), purity (HPLC, typically >99%), residual solvents, water content and endotoxin levels (USP <85>). Manufacturing is audited to GMP standards. Documentation is available on request via Telegram.
Shipping, packaging, and returns
All orders ship in plain, unbranded outer packaging with tracked shipping. US and EU orders typically arrive in 3–5 business days. Glass vials are shock-protected in molded foam inserts. Because our peptides are sterile research reagents, we cannot accept returns on opened vials — but we will replace any vial that arrives damaged or fails inspection at our expense (photo evidence required within 48 hours of delivery).
