Every peptide batch includes a Certificate of Analysis from SafeCert Labs, an independent CLIA certified facility. All chemical analysis is performed using HPLC with UV Detection coupled with Mass Spectrometry.

We’re the only research peptide supplier offering independent third-party testing by three different certified labs. Our testing protocols verify molecular identity, CAS number confirmation, purity levels (98%+ or 99%+), and appearance specifications.

All COAs are available before purchase so you can verify quality standards for your research applications.

Each COA displays the assession number, received date, reported date, and your specific product information (CAS number, quantity, identity, purity percentage, and appearance).

You’ll see two graphs: the HPLC chromatogram showing the purity peak, and the mass spectrometry data confirming molecular weight and identity. The specification table provides the result summary with exact purity percentage.

Every COA includes the testing lab’s principle chemist signature and the testing methodology used. Product photos show the actual vial appearance and labeling for verification.

Research applications typically require 95-99%+ purity for reliable results. Lower purity can introduce variables that interfere with in vitro studies and compromise data integrity.

Our 99%+ purity variants meet pharmaceutical-grade standards. Higher purity reduces experimental noise and gives you cleaner baseline data for your research protocols.

Store lyophilized peptides at -20°C in their original sealed vials. Keep them away from light and humidity.

Under these conditions, our research-grade peptides maintain stability for 3-5 years. The sealed environment with desiccant protection preserves molecular integrity for long-term laboratory use.

Reconstituted solutions remain stable for several days at 2-8°C. For longer storage, create small aliquots and freeze at -20°C or -80°C.

Avoid repeated freeze-thaw cycles. Use sterile bacteriostatic water and aseptic technique when preparing solutions for multiple-use research applications.

Most in-stock peptides ship the same day on orders placed before 12 PM PT. Domestic US orders arrive in 3-5 business days via standard shipping, or 1-2 days expedited.

We ship lyophilized peptides at ambient temperature in protective packaging. Free shipping on orders over $50.

We ship worldwide to qualified research institutions and laboratories. All international shipments include proper documentation: commercial invoices, Certificates of Analysis, MSDS, and “research use only” declarations.

Shipping times vary by region. You are responsible for any customs duties or import requirements in your jurisdiction.

Standard vial sizes range from 2mg to 10mg per peptide. We offer volume discounts starting at 3 vials (4-10% discount).

Research peptides sold “for research purposes only” are legal to purchase in most jurisdictions when clearly labeled for laboratory use.

Our products are intended exclusively for in vitro research by qualified professionals. They are not FDA-approved for human consumption or veterinary use. Regulations vary by location, so verify your local requirements.

This disclaimer indicates our peptides are research-grade compounds for laboratory applications only. They haven’t been evaluated by the FDA for human safety or efficacy.

We maintain strict regulatory compliance. All products are manufactured and labeled for scientific research purposes under Good Manufacturing Practices.

Due to temperature-sensitive storage requirements and the nature of research compounds, we don’t accept returns on shipped peptides.

We accept returns on unopened supplements within 10 days of delivery; all returns are subject to a 15% restocking fee and will be refunded minus the cost of the return shipping label.

Email us at hello@peptidelabs.co for product questions, technical specifications, or order assistance. We respond within 24-48 hours during business hours (Monday-Friday, 9 AM-5 PM PT).

Contact us immediately if tracking shows delivery but you haven’t received your package. If the carrier confirms non-delivery, we’ll reship at no cost.

We stand behind our shipping guarantee. Your research timeline matters, and we work quickly to resolve any delivery issues.
