- 02
Analysis
Every lot is evaluated by reverse-phase HPLC and mass spectrometry to confirm identity and quantify purity.
- 03
Documentation
Independent certificates of analysis detail identity, purity and analytical method, and are published in the COA library.
- 04
Fulfilment
Lyophilized vials are sealed, cold-handled and dispatched discreetly within 24 hours of order confirmation.
Purity is a claim. Ours comes with the data.
Independent laboratories evaluate our compounds so you can trust what enters your experiment. Certificates are published as issued, so you can review them before you order.
- Reverse-phase HPLC purity quantification on every lot

Questions researchers ask
Clear answers on purity, storage, reconstitution and compliance. Everything you need to order with confidence.
Read all FAQsAll NUPEPS Peptides products are intended strictly for in-vitro laboratory research and development. They are not drugs, supplements, cosmetics or food, and are not intended for human or animal consumption, diagnostic, or therapeutic use. By ordering, you confirm you are a qualified researcher or institution.
Every production lot is evaluated by reverse-phase HPLC for purity quantification and by mass spectrometry for identity confirmation. Certificates of analysis (COAs) are published in the COA library, so they can be reviewed before purchase.
Lyophilized peptides are best stored at -20°C in a desiccated, light-protected environment, where they remain stable for extended periods. Once reconstituted with bacteriostatic water, store refrigerated at 2–8°C and use within the window described in the product documentation.
You will need bacteriostatic water (0.9% benzyl alcohol), a sterile syringe and an appropriate laboratory workspace. We stock 3 mL and 10 mL bacteriostatic water vials under Research Supplies. Reconstitution should always be performed by trained personnel.
Orders confirmed before the daily cut-off are dispatched within 24 hours in discreet, temperature-considerate packaging. Domestic orders over $200 ship free. Tracking is provided by email once your order leaves our facility.
Built for qualified researchers and institutions
NUPEPS Peptides compounds are supplied strictly for laboratory research and in-vitro use. They are not for human or veterinary consumption. By purchasing, you confirm you understand and accept responsible, compliant handling.
