Frequently
Asked Questions

What are research peptides and how are they used?

Research peptides are short chains of amino acids synthesized for use in scientific and laboratory studies. At Irvine Peptide Labs, our peptides are produced to strict research-grade standards and are intended solely for laboratory and in-vitro research purposes. They are not intended for human or veterinary consumption.

Every batch at Irvine Peptide Labs undergoes third-party testing at an independent, certified laboratory. A Certificate of Analysis (CoA) showing purity, peptide identity, and potency is available on each product page so you can verify exactly what you’re receiving before you order.

Irvine Peptide Labs ships all orders from within the United States. Standard domestic orders typically arrive within 3–5 business days. Expedited options are available at checkout. All orders are packaged discreetly and include a tracking number sent to your email once dispatched.
 
Lyophilized (freeze-dried) peptides should be stored in a cool, dry place away from direct light — ideally refrigerated at 2–8°C for short-term use or frozen at −20°C for long-term storage. Avoid repeated freeze-thaw cycles and exposure to moisture, which can degrade peptide integrity over time.
 
 

All Irvine Peptide Labs peptides are manufactured to a minimum purity of 99% as verified by High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) analysis. These tests confirm both the identity and concentration of the compound, ensuring you receive exactly what is listed — nothing more, nothing less. The full purity report is attached to each product’s Certificate of Analysis.
