Purity you can
put on record.
Lonerlabs supplies lyophilized research peptides to laboratories, universities, and independent investigators. Every lot is assayed by an independent facility, and the certificate is matched to the vial in your hand — not to a generic sample.
Third-party tested
Every production lot goes out for independent HPLC and mass spectrometry before it's released for sale.
Lot-matched COAs
The certificate you download is tied to the lot number printed on your vial. Look it up before you open it.
Cold-chain packing
Lyophilized vials ship in insulated mailers with gel packs, sealed against light and moisture.
Same-day dispatch
Orders confirmed before 2:00 PM MT ship the same business day with tracking issued at pickup.
Current inventory
A working selection from the full catalog. Specifications, lot data, and available fill sizes are listed on every item.
From order to bench
Place the order
Select fill sizes and check out. You'll confirm research-use terms before payment is taken.
Lot assignment
Your vials are pulled from a released lot and the matching COA is attached to your order record.
Cold pack & ship
Insulated packing, gel packs, tamper-evident seal. Tracking is emailed the moment the label scans.
Verify on arrival
Enter the lot number from your vial in the COA portal and confirm the assay before you reconstitute.
Terms of sale
Lonerlabs products are supplied strictly as laboratory reference materials for in-vitro and non-clinical research conducted by qualified professionals. They are not drugs, dietary supplements, cosmetics, or food, and they have not been evaluated or approved by the FDA or any comparable authority for the diagnosis, treatment, cure, or prevention of any condition.
Nothing on this site is medical advice, and no dosing, administration, or protocol guidance is provided. Purchasers assume full responsibility for lawful handling, storage, and disposal in their jurisdiction, and for compliance with all institutional and regulatory requirements. By placing an order you confirm you are 21 or older and are purchasing for research use only. We do not sell to individuals intending human or animal consumption, and orders that indicate such intent are cancelled and refunded.
Research catalog
All items ship lyophilized and sealed. Specifications reflect the current released lot; the certificate of analysis for your specific lot is available in the COA portal after purchase.
Purity & certificates of analysis
Every lot is tested twice: once by the manufacturing facility, once by an independent laboratory with no stake in the result. We publish the independent report.
Verify your vial
Enter the lot number printed on the vial label. Sample lots for demonstration: LL-4471, LL-4477, LL-4480.
What gets tested
Release threshold is 98.0% area purity. Lots below threshold are quarantined and destroyed — they are not repackaged, discounted, or sold as a lower grade.
Storage & stability
−20°C, dark
Unopened lyophilized vials are stable long-term when kept frozen and shielded from light.
Ambient tolerant
Lyophilized powder tolerates short ambient excursions during shipping without measurable degradation.
2–8°C, short term
Once in solution, stability drops sharply. Store cold and use within the window noted on the COA.
Freeze-thaw cycles
Repeated cycling degrades peptide integrity. Aliquot on first reconstitution rather than re-freezing stock.
Built for people who read the certificate
Lonerlabs was started because sourcing research peptides had become an exercise in taking someone's word for it. Certificates that didn't match lot numbers. Purity figures with no method listed. Vendors who couldn't say which facility ran the assay, or whether one had been run at all.
We built the operation around a single rule: nothing ships without an independent report attached to it, and that report is available to the customer before the vial is opened. If a lot fails, it doesn't get quietly moved into a different SKU. It gets destroyed.
We supply university labs, contract research organizations, and independent investigators. We do not supply consumers, and we do not provide protocols, dosing information, or any guidance on administration to humans or animals. That line is not negotiable, and it's the reason we can operate transparently.
What we don't do
No dosing guidance. No protocol design. No claims of therapeutic effect. No sales to anyone indicating intent for human or veterinary use. Requests of that kind are declined and the order is refunded.
