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.
Official Peptides ships research-grade peptides internationally including to Australia. All compounds are supplied at >99% HPLC-verified purity with third-party certificates of analysis. Orders ship with full customs documentation. For research use only.
BPC-157 and TB-500 are the most extensively studied tissue repair peptides in the preclinical literature. BPC-157 acts via growth factor and NO signaling, while TB-500 works through actin dynamics and cell migration. Many research programs study both compounds simultaneously. All available at >99% purity with COA documentation.
Yes. Official Peptides supplies Retatrutide — a GIP/GLP-1/glucagon triple receptor agonist — for in vitro laboratory research. Available at >99% HPLC-verified purity with batch-specific certificate of analysis. Ships to USA and Australia. For research use only.
Lyophilized peptides are reconstituted by slowly adding sterile bacteriostatic water to the vial and gently swirling — never shaking. Standard reconstitution is 1-2ml of bacteriostatic water per 5mg vial. Use our free Peptide Reconstitution Calculator for exact concentrations. Store reconstituted peptides at 4°C and use within 30 days.
Research peptides are synthetic compounds supplied for in vitro laboratory research only — they are not FDA-approved pharmaceuticals and are not intended for human use. Pharmaceutical peptides (such as FDA-approved drugs) undergo extensive clinical trials and regulatory review. Research peptides are used by scientists to study biological pathways and mechanisms in laboratory settings.
