About Peptide Foundry — Built by Curiosity, Driven by Quality

Peptide Foundry LLC is a family-owned, US-based supplier of research peptides manufactured in cGMP-certified facilities and third-party tested by Freedom Diagnostics. We were founded by a team passionate about advancing peptide science and committed to providing researchers with high-purity materials at accessible prices.

Our Mission

Our mission is to provide research-grade peptides with full transparency, rigorous third-party testing, and pricing that doesn't gatekeep scientific discovery. As a family-owned and operated company, we hold ourselves to a higher standard. Every product we carry is selected for its research value, rigorously tested by independent laboratories, and backed by full documentation.

Core Values

Scientific Rigor: Every peptide undergoes multi-panel third-party testing. We publish Certificates of Analysis for every product and every lot. No exceptions.
Family Operated: We're not a faceless distributor. Peptide Foundry is family-owned, and every order is handled with the care and accountability that comes with it.
Accessible Pricing: Quality research materials shouldn't break the budget. We keep our margins fair so more labs and researchers can access what they need.
US Manufactured: Every peptide we carry is synthesized in a cGMP-certified facility based in the United States, ensuring consistent quality and regulatory compliance.

Testing Protocols

Every batch is independently tested by Freedom Diagnostics before it's made available. Here's exactly what we screen for:

Purity (HPLC): High-performance liquid chromatography confirms peptide identity and purity levels. Each Certificate of Analysis reports exact purity percentages (99%+ standard) so researchers know precisely what they're working with.
Endotoxins (LAL Assay): Limulus Amebocyte Lysate testing screens for bacterial endotoxins that could compromise research results. We test every lot to ensure levels fall well within acceptable limits.
Heavy Metals (ICP-MS): Inductively coupled plasma mass spectrometry detects trace heavy metal contamination. This ensures research materials are free from lead, mercury, arsenic, and cadmium.

The Foundry Club

Foundry Club is our membership program for serious researchers. Members unlock wholesale pricing on every peptide in our catalog, get priority order handling, and receive early access to new products as they're released. More than a discount, it's a community of curious minds who share a passion for discovery.
