Third-Party Testing
Every batch undergoes independent HPLC and mass spectrometry analysis. Purity reports and chromatograms are included with your COA — not buried in fine print.
About Formal Peptides
Research-grade peptides for qualified laboratories — verified purity, transparent documentation, USA fulfillment.
Our Mission
Science-First Peptide Supply
Formal Peptides supplies research-grade lyophilized peptides to universities, private laboratories, and qualified research organizations across the United States. Every compound is independently tested for identity and purity, with batch-specific Certificates of Analysis (COA) linked to every vial.
We believe researchers deserve complete transparency — not marketing claims. That is why every product page includes CAS numbers, molecular data, storage guidance, and third-party HPLC verification before it ships.

Why Researchers Choose Us
Full Documentation
Product pages include CAS numbers, molecular weight, formula, storage conditions, and reconstitution guidance — everything your lab needs for protocol planning.
Fast USA Fulfillment
Orders ship from the United States with 1–2 business day processing. Free shipping on qualifying orders over $150 for verified research buyers.
Research-Only Focus
We serve qualified laboratories and institutions only. All products are strictly for in-vitro research — never for human or animal consumption.
Quality You Can Verify
Formal Peptides was built on a single principle: if you cannot verify it, you should not use it in your research. Our quality pipeline includes:
- Lyophilized peptides stored at controlled temperatures until shipment
- Batch-specific HPLC purity verification (typically 99%+)
- Mass spectrometry identity confirmation
- QR-coded COA accessible from every product vial
- Transparent product attributes: CAS, MW, formula, and storage
Who We Serve
Formal Peptides partners with research institutions that require documented, reproducible peptide supply chains. Our customers include university research departments, private R&D laboratories, biotechnology firms, and qualified independent researchers conducting in-vitro studies.
Purchasers must be 18 years or older and agree that all products are intended exclusively for laboratory research purposes. We do not sell to consumers seeking products for personal use.
