Built by chemists who got tired of mystery vials.
Nu Peptides is a research-grade peptide synthesis company based in Austin, Texas. We run Fmoc solid-phase chemistry from raw building blocks rather than repackaging bulk material, and every batch is verified in-house and again by an independent ISO-17025 laboratory before release. Each vial ships with a structured certificate of analysis and a nine-character Nu ID that resolves to its full synthesis log.
To make research peptides traceable, verifiable, and reproducible — so the data that comes off your bench reflects the compound, not the vendor.
Every product we offer is fulfilled in the United States to the highest laboratory standards, then verified with third-party laboratory testing to confirm identity and purity before it is ever listed. We don't take a claim at face value — we require the data to back it.
That commitment runs deeper than a single assay. From sourcing and handling to packaging and documentation, every step is built around one principle: reproducible, research-grade quality, batch after batch.
Because we've built direct relationships with our manufacturing partners, we're able to pass meaningful savings on to the researchers who rely on us without ever compromising on what matters.
A team that treats quality as the product.
We're operators and peptide enthusiasts who grew tired of inconsistent certificates of analysis and vendors who couldn't answer a simple question: what's actually in this vial?
So we built Nu Peptides around one idea: transparency. Premium-quality peptides, sourced to exacting standards, documented with a Certificate of Analysis, and supported by a team that genuinely cares about the work you do.
Thousands of researchers across academic, clinical, and independent labs now trust Nu for material they can stake their results on — and that trust is something we re-earn with every order.
Six commitments
behind every vial.
These aren't taglines. They're the operating standards we hold every lot, every partner, and every shipment against — the reasons researchers choose Nu and stay.
Uncompromising purity
Every peptide is verified to ≥99% purity by HPLC, with mass-spec confirmation of identity.
Made in the USA
All products are manufactured domestically to strict laboratory and quality standards.
Third-party tested
Every product lot is backed by accredited third-party laboratory testing before it's listed — no exceptions.
Batch consistency
Standardized processes mean the vial you order today matches the one you order next year.
Scientific integrity
We publish the numbers, the traces, and the lot data. No marketing language, just evidence.
Fair, transparent pricing
Direct manufacturer relationships let us pass real savings on to the researchers we serve.
Standards you can measure because we measured them first.
