Pep Plus Labs supplies research-grade synthetic peptides for laboratory use — each lot verified by third-party HPLC and mass spectrometry, and shipped with the certificate of analysis to prove it.
Five research compounds, each synthesized to ≥99% purity. Select one to view its profile and current lot documentation.
Every vial carries a lot number. Enter it to pull that lot’s analytical record — purity, identity confirmation, and release date.
SAMPLE LOTS —
Anyone can print “99% pure” on a label. We hand you the chromatogram.
Every lot is analyzed by an independent laboratory with no stake in the result. Purity is measured by high-performance liquid chromatography; identity and molecular weight are confirmed by mass spec. Both come back in the COA — reproduced in full, not summarized.
Vacuum freeze-dried and crimp-sealed in amber borosilicate under inert atmosphere.
Insulated packaging with gel packs; lot numbers recorded at the moment of dispatch.
Every vial carries a lot number that ties back to its synthesis record, chromatogram, and spectra. Ask for the archive on any batch, any time — it’s already on file.
Five stages. A lot that fails any of them never ships.
Solid-phase peptide synthesis under controlled conditions, cleaved and purified by preparative HPLC.
Independent HPLC and mass-spec analysis. Below-spec lots are rejected, never downgraded and resold.
Vacuum freeze-drying to a stable powder, then filling and crimp-sealing under inert atmosphere.
COA generated and bound to the lot number, with chromatograms and spectra archived against it.
Cold-chain packing with same-day tracking on orders confirmed before 14:00.
Compound, quantity, institution. We reply within one business day with pricing and current lot documentation.
Orders are accepted from research institutions, universities, and laboratory professionals. Materials are supplied strictly for in-vitro and laboratory research.
A certificate of analysis with HPLC chromatogram, mass-spec confirmation, lot number, synthesis date, and storage guidance — with every shipment.
Lyophilized peptides should be stored at −20 °C, protected from light. Specific handling notes accompany each compound’s documentation.
No. Pep Plus Labs supplies raw research materials and analytical documentation only. We do not provide administration, dosing, or protocol guidance of any kind.
Sealed vials cannot be returned once dispatched. Any lot that fails to match its COA is replaced or refunded in full.
