Purity you can document, not just claim
NUPEPS Peptides exists to give researchers reference-grade compounds backed by verifiable analytics — tested, documented and published, so your results start with material you can trust.
Verified purity on qualifying lots
Lots tested by HPLC + MS
Dispatch on confirmed orders
Independent lab documentation
HPLC purity analysis
Reverse-phase high-performance liquid chromatography quantifies purity for every lot, documented to ≥99% on qualifying batches.
Mass spectrometry identity
Each compound is confirmed by mass spectrometry so the molecular identity in the vial matches the sequence on the label.
Published COAs
Certificates of analysis are published as issued by the testing laboratory and can be reviewed before purchase — no anonymous, undocumented material.
Cold-chain logistics
Lyophilized compounds are handled and shipped with temperature-considerate, discreet packaging to preserve stability in transit.
From synthesis to your bench
A four-stage chain of custody keeps every vial accountable to its certificate of analysis.
Synthesis & sourcing
Compounds are produced to defined specifications and received into a controlled, documented intake process.
Independent testing
Every lot is analyzed by HPLC and mass spectrometry. Material that does not meet specification never reaches the catalog.
Documentation
Results are compiled into a certificate of analysis and published in the COA library.
Storage & fulfillment
Verified lots are stored under controlled conditions and dispatched within 24 hours of a confirmed order.
Certificates, published as issued
A certificate of analysis documents the tests an independent laboratory performed — identity, purity and screening results. We publish the reports themselves rather than summarising them. This one is the certificate for BPC-157 10mg, exactly as it appears in the library.
- Issued by the testing laboratory, not rewritten by us
- Identity confirmed by mass spectrometry
- Purity quantified by reverse-phase HPLC
- Published in the COA library for every certificate we hold
