Minimum purity, or the lot is rejected
Not an average across past batches — a threshold. Material below it is destroyed rather than discounted into a second-tier line.

Seven flagship reference materials, each with a published certificate of analysis traceable from the label back to the instrument run.

Minimum purity, or rejected
A floor, not an average. Material below threshold is destroyed rather than discounted into a lower-grade line.

Assays on every lot
Purity, identity, endotoxin, heavy metals, net peptide content and residual solvents — run by a lab we do not own.

Order to dispatch
Orders placed before 2pm CT leave the facility the same business day, insulated and temperature-logged.
— Our positionThe research peptide industry
The research peptide industry
has a transparency problem.
We built LUMEN because researchers deserve a supply chain they can audit — not marketing copy and an unverified number on a label.
Most suppliers
“Trust us — it’s 99% pure.”
- No independent third-party testing
- No batch-level documentation
- Synthesis origin undisclosed
- Ambient shipping, no cold chain
- Purity claimed, never evidenced
LUMEN
“Here’s the COA. Verify it yourself.”
- Independent HPLC + LC-MS, every batch
- Public certificate of analysis per lot
- Fully domestic synthesis and fulfilment
- Insulated, temperature-controlled dispatch
- Chromatograms published, not summarised
— Why LUMENBuilt for the lab,
Built for the lab,
not the shelf.
Six things every researcher should be able to expect from a peptide supplier — and the reason we publish evidence for all six rather than asserting them.

— Panels
Curated panels.
Multi-vial sets assembled by our research team and dispatched from a single cold-chain run, so lot conditions stay comparable.
— Our standards
Commitments, not adjectives.
Every claim below is a rule we hold ourselves to and publish evidence for — not a statistic about orders you cannot inspect.
Every lot
Independently assayed
Purity by RP-HPLC and identity by LC-MS, at an ISO/IEC 17025 accredited laboratory we do not own. A test we controlled would not be a third-party test.
Published
Certificate, not a summary
The chromatogram itself goes into the COA library against its lot number, so the number on the label can be checked rather than trusted.
US only
Synthesis, testing and dispatch
United States end to end. No international transshipment at any stage, which keeps the cold chain short and the paper trail intact.

Everything researchers
ask before ordering.
Can’t find what you’re looking for? Get in touch — median response is under four hours.
Yes, end to end. Synthesis, analytical testing, lyophilisation, storage and fulfilment all occur within the United States. Nothing is transshipped internationally at any point, and the facility address is on file with every order.
Every batch is run by reverse-phase HPLC at 214nm for purity and by LC-MS for identity confirmation, at an ISO/IEC 17025 accredited laboratory that we do not own or control. Endotoxin and heavy metals panels are run in parallel. We publish the chromatogram itself, not just the headline percentage.
A batch-matched certificate of analysis containing the lot ID, assay date, purity by HPLC, identity confirmation by LC-MS, endotoxin result, heavy metals panel and storage conditions. The same certificate is publicly resolvable from the lot ID printed on the vial label.
Orders placed before 2pm CT on a business day leave the facility the same day. Everything ships insulated with a temperature logger, fully tracked, signature on delivery.
Lyophilised material is stable at −20°C for long-term storage and 2–8°C for short-term handling. Protect from light. Specific stability data for each compound is included in its certificate of analysis.
No. Every compound sold by Lumen Peptides, Inc. is supplied strictly as a reference material for in-vitro laboratory research by qualified professionals. These are not drugs, foods, cosmetics or medical devices, they have not been evaluated by the FDA, and they are not intended for human or veterinary consumption, therapeutic use, or any in-vivo application.
