About
A laboratory, not a marketplace.
Lyos Labs supplies lyophilized research peptides of verified purity to researchers across the United States. We operate as a small, independent supplier — every lot released under our name passes through the same controlled analytical pathway.
Precision is a discipline, not a claim.
We began Lyos Labs because we were unable to find a supplier that would provide full chromatographic traces, lot provenance, and the identity data our research work required. We decided the most efficient response was to build the supplier we had been looking for.
Our focus is narrow on purpose. A tightly curated catalog, a single fulfillment facility, one third-party analytical laboratory. The narrower the surface area, the more reliably each lot can be documented.
Three fixed disciplines
Verified Purity
Every released lot carries a Certificate of Analysis prepared by Kovera Labs, an independent analytical laboratory — RP-HPLC purity analysis, peak area integration, and full chromatograms.
Domestic Fulfillment
Orders ship within the 50 United States plus the District of Columbia, dispatched same-day or next business day with tracked carriers.
Lot Traceability
Every shipment is associated with a specific synthesis lot and Certificate of Analysis, retained for the duration required by U.S. federal regulation.
Quality assurance framework
RP-HPLC Purity Analysis
Every lot is analyzed using reversed-phase high-performance liquid chromatography (RP-HPLC) by Kovera Labs, an independent third-party laboratory. Purity is determined by peak area integration, with all lots verified to ≥98% purity.
Full UV chromatograms (220 nm and 280 nm) are included in every Certificate of Analysis, allowing researchers to verify peak purity and detect potential impurities or degradation products.
Third-Party Certificates
We partner with independent third-party analytical laboratories for verification. Certificates of Analysis include batch-specific data: lot number, synthesis date, expiration date, storage recommendations, and full analytical traces. Lot-level traceability is maintained for research recordkeeping requirements.
CoAs are provided as downloadable PDFs for each product. Lot-specific certificates are available upon request.
Controlled Analytical Production
All peptides are synthesized via solid-phase peptide synthesis (SPPS) using Fmoc chemistry under controlled analytical practices consistent with research-reagent production. Synthesis is followed by preparative HPLC purification to ≥98% purity. Final products are lyophilized (freeze-dried), packaged in amber glass vials, and sealed under inert atmosphere (argon or nitrogen).
Research-Grade Logistics
Tracked courier delivery in protective packaging. Lyophilized peptides are shelf-stable at ambient temperature for 30+ days — refrigeration during transit is unnecessary for the lyophilized form. Upon receipt, researchers store at 2-8°C (medium-term) or -20°C (long-term).
Research Use Only enforcement
Research Use Only Eligibility
All products are supplied exclusively for in vitro research and preclinical studies. Purchasers must be at least 21 years old and must accept Research Use Only terms acknowledging that products are not for human consumption, veterinary use, or clinical application.
Regulatory Transparency
Lyos Labs products are not approved by the FDA or any regulatory authority for human use. They are not registered as drugs, medical devices, or dietary supplements. Materials with additional regulatory, patent, or channel restrictions are handled under heightened internal review and are not positioned for clinical, diagnostic, veterinary, or consumer use.
No administration guidance
Lyos Labs does not provide dosing, injection, reconstitution, administration, clinical protocol, or human-use guidance. Public pages stay limited to research-use eligibility, analytical documentation, lot traceability, and ordering restrictions.
