A research-grade peptide supplier built around documentation and compliance.
Peptides Bioscience is a U.S.-based supplier of synthetic peptides and related reference compounds intended exclusively for in-vitro laboratory research. Every product ships with a third-party Certificate of Analysis and is sold under strict Research Use Only terms.
What we do
We supply synthetic peptides and related reference materials to qualified researchers working in academic, institutional, and independent laboratory settings.
Reference compounds
Lyophilized synthetic peptides characterized by HPLC and mass spectrometry for use in receptor-binding, signaling, structural, and assay-development studies.
Documented batches
Every lot ships with a third-party Certificate of Analysis. COAs are published on each product page so any buyer can verify identity and purity before purchase.
Cold-chain handling
Materials are stored and shipped under appropriate temperature control with handling instructions included in each shipment.
Education, not marketing
Our product pages describe what a compound is — its peptide family, receptor class, and reported in-vitro mechanism — never what it does for a person.
Compliance posture
We operate as a Research Use Only supplier. Our policies are written, enforced at checkout, and reflected in every page of this site.
- No human-use claims, anywhere
We do not describe outcomes, benefits, dosing, indications, or therapeutic effects for any compound. Product copy describes chemistry and mechanism only.
- Researcher confirmation
Buyers must confirm they are 21+ and a qualified researcher before entering the catalog. Researcher status is reaffirmed at checkout.
- No medical advice
We do not provide medical, clinical, dosing, or therapeutic guidance under any circumstance. Inquiries of that nature are declined.
- Transparent pricing
All prices, shipping fees, and any taxes are disclosed in the cart before payment. No hidden fees, no surprise charges.
- Clear billing descriptor
Card statements show a descriptor that matches the legal business name so customers can recognize the charge.
- Accessible support
Real humans answer email and phone Monday–Friday during business hours. Contact details are published on every page.
Quality program
Identity and purity are verified by an independent third-party laboratory before any lot is released for sale.
Third-party verified
Each lot is analyzed by an independent contract laboratory; COAs are issued by that lab, not by us.
Analytical methods
Reverse-phase HPLC for purity and quantitation; ESI-MS for identity confirmation. Method details accompany each COA.
Who we sell to
Peptides Bioscience sells to qualified researchers and research institutions — for example, academic laboratories, contract research organizations, analytical and method-development labs, and credentialed independent investigators conducting in-vitro work.
We do not sell to consumers, patients, clinicians for human or veterinary administration, compounding pharmacies, or anyone intending in-vivo use of these materials. Orders that indicate a non-research intent will be declined and refunded.
