FAQs
What are research peptides?
Research peptides are short chains of amino acids used in laboratory and scientific settings to study biological responses, cellular pathways, and therapeutic potential. Nexara Labs sells peptides strictly for research use only and not for human consumption.
Are your peptides made in the United States?
Yes. All Nexara Labs peptides are manufactured, purified, and tested in a U.S.-based laboratory operating under cGMP-compliant conditions.
What purity levels do your peptides have?
Our peptides undergo HPLC and Mass Spec testing and consistently measure 98–99%+ purity. Each batch is internally validated for identity, purity, and stability.
Do your peptides come with a Certificate of Analysis (COA)?
Yes. Every batch includes an internal COA confirming:
- Purity percentage
- Molecular identity
- Â Lot number
- Â Production date
- Â Testing method (HPLC/MS)
COAs are available upon request.
Are your products sterile?
Our vials are aseptically handled and sealed, but peptides are sold as non-sterile research materials and not intended for injection, human consumption, or veterinary use.
How should peptides be stored?
For maximum stability:
- Store lyophilized (powdered) peptides at 2–8°C (refrigerated)
- For long-term storage, freeze at -20°C
- Avoid repeated freeze–thaw cycles
