Peptides are short chains of amino acids linked by peptide bonds. They are smaller than proteins and play crucial roles in biological processes. Our peptides are synthesized for in-vitro research and laboratory use only.

Are your peptides for human consumption?

No. All products sold by Experts Only Research are strictly for laboratory and research purposes only. They are not intended for human or animal consumption, and should not be used as food, drugs, or cosmetics.

What is a Certificate of Analysis (COA)?

A COA is a document from an independent laboratory that verifies the identity, purity, and quality of a compound. Every Experts Only Research product undergoes HPLC and mass spectrometry testing. COAs are available for download on each product page.

How are your peptides shipped?

All orders are shipped in temperature-controlled, discreet packaging via USPS or UPS. Orders placed before 2pm EST ship same day. Standard shipping typically arrives within 2-5 business days.

Do you offer bulk or wholesale pricing?

Yes. We offer volume discounts for research institutions, universities, and qualified laboratories. Please contact us through our inquiry form for custom quotes on bulk orders.

What is your return policy?

Due to the nature of our products, we cannot accept returns on opened items. Unopened products may be returned within 30 days of purchase for a full refund. If you receive a damaged or incorrect product, contact us immediately for a replacement.

What testing methods do you use?

Every compound undergoes dual-method verification: High Performance Liquid Chromatography (HPLC) confirms purity percentage, and Liquid Chromatography-Mass Spectrometry (LC-MS/MS) confirms molecular identity. Both tests are conducted by independent third-party laboratories.

How should peptides be stored?

Lyophilized (dry) peptides should be stored at -20°C for long-term stability, or at 2-8°C for short-term use (up to 6 months). Reconstituted peptides should be refrigerated at 2-8°C and used within 4 weeks. Avoid repeated freeze-thaw cycles.

Understanding Peptide Reconstitution: A Complete Lab Guide

Complete guide to reconstituting lyophilized research peptides.

Reconstituting lyophilized peptides is a fundamental skill for any research laboratory. This guide covers the essential principles, best practices, and common mistakes to avoid.

Why Proper Reconstitution Matters

The reconstitution process directly impacts compound stability, dosing accuracy, and experimental reproducibility. Incorrect technique can lead to peptide degradation, aggregation, or contamination.
