What are research-grade peptides?

Accepted Answer

Research-grade peptides are synthetic amino acid chains produced under strict quality control standards for use in scientific and laboratory research. They are not intended for human consumption or therapeutic use. Our peptides meet or exceed 98% purity standards, verified by third-party HPLC and mass spectrometry analysis.

Question 3

How do you verify peptide purity?

Accepted Answer

Every batch undergoes rigorous quality control testing including High-Performance Liquid Chromatography (HPLC) for purity verification, Mass Spectrometry (MS) for molecular weight confirmation, and amino acid analysis. Certificates of Analysis (CoA) are available for every product and batch upon request.

Question 4

Do you provide Certificates of Analysis?

Accepted Answer

Yes. A Certificate of Analysis (CoA) is available for every product and every batch we produce. The CoA includes purity percentage, HPLC chromatogram, mass spectrometry data, and batch number. You can request a CoA by contacting our team or downloading it directly from the product page.

Question 5

What are your shipping options?

Accepted Answer

We offer standard shipping (5-7 business days) and expedited shipping (2-3 business days). We are USA-based and ship domestically within the United States only. All orders are fulfilled and shipped within 24 hours of purchase.

Question 6

How should peptides be stored upon receipt?

Accepted Answer

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage (up to 24 months) or at 4°C for short-term use (up to 3 months). Once reconstituted, peptide solutions should be stored at 4°C and used within 30 days. Avoid repeated freeze-thaw cycles to maintain integrity.

Question 7

What is your return and refund policy?

Accepted Answer

Due to the nature of research chemicals, we do not accept returns on opened products. If you receive a damaged or incorrect product, please contact us within 48 hours of receipt with photographic evidence. We will arrange a replacement or full refund at our discretion. Unopened products may be returned within 14 days.

Question 8

Are your peptides legal to purchase?

Accepted Answer

The legal status of research peptides varies by jurisdiction. In the United States, most research peptides are legal to purchase for research purposes and are not scheduled substances. However, it is your responsibility to verify the legal status in your country or region before ordering. Nucentra Labs complies with all applicable US federal and state regulations.

Question 9

Are these products intended for human use?

Accepted Answer

Absolutely not. All products sold by Nucentra Labs are strictly for in vitro and in vivo research purposes only. They are not approved by the FDA for human consumption, therapeutic use, or veterinary use. Any use outside of legitimate scientific research is strictly prohibited and violates our terms of service.

Question 10

How do I reconstitute lyophilized peptides?

Accepted Answer

Reconstitution should be performed using bacteriostatic water or sterile water for injection. Add the solvent slowly to the vial, allowing it to run down the sides rather than directly onto the powder. Gently swirl (do not shake) until fully dissolved. The recommended concentration depends on your specific research protocol. Always use aseptic technique.
