Frequently Asked Questions

Research peptides are synthetic compounds used in laboratory research to study biological processes. They are not approved for human use and are intended strictly for in vitro research applications by qualified scientists.

All compounds are supplied at >99% purity verified by HPLC analysis conducted by independent third-party laboratories. Mass spectrometry identity confirmation is also performed on every batch.

Every product page includes a live COA viewer showing the most recent batch certificate. You can also contact lab@officialpeptides.net with your order number for batch-specific documentation.

We currently accept cryptocurrency payments including Bitcoin, Ethereum, and USDC. Payment instructions are provided at checkout.

Lyophilized peptides should be stored at -20°C away from light and moisture. Reconstituted peptides should be stored at 4°C and used within the timeframe specified on each product page.

Yes. Official Peptides is a US-based supplier. All products ship domestically, eliminating customs delays and cold chain risks associated with international peptide imports.
