π¬ Products & Quality
Are your peptides for human consumption?
No. All products sold by Valley Research are strictly for laboratory and research purposes only. They are not intended for human consumption, veterinary use, or any therapeutic application. By purchasing, you confirm you are a qualified researcher.
Where are your peptides manufactured?
All of our peptides are synthesized in USA-based laboratories that follow strict quality control protocols. We source exclusively from facilities that maintain high manufacturing standards to ensure consistent purity and reliability.
Do you provide Certificates of Analysis (COAs)?
Yes β every single product. Each batch undergoes independent third-party testing via HPLC and mass spectrometry. A full COA is included with every order. You can also request COAs before purchasing by contacting us.
What is the purity of your peptides?
All products in our catalog are 99%+ purity, verified by independent HPLC analysis. We do not sell anything below this threshold. Every COA documents the exact purity level for full transparency.
What are peptide kits / blends?
Blends are pre-mixed combinations of complementary peptide compounds in a single vial, offered at a discounted price compared to purchasing individually. Designed for researchers running multi-compound studies who want the convenience of a single reconstitution.
π Shipping & Orders
How fast do you ship?
Orders are processed and shipped within 24 hours on business days. Standard shipping typically arrives in 3β5 business days. Expedited options are available at checkout. All orders ship from our Arizona facility in discreet, temperature-conscious packaging.
Is shipping free?
Free standard shipping on all orders over $150. Orders under $150 ship for a flat rate of $7.95. We ship to all 50 US states.
What is your return and issue resolution policy?
All sales are final. Due to the nature of research-grade biochemical compounds, we are unable to accept returns or exchanges under any circumstances. Once a product leaves our facility it enters a research supply chain with strict handling requirements β we cannot verify storage conditions after delivery, and accepting returns would compromise the integrity of our inventory and the safety of other researchers.
If there is a problem with your order, we will investigate and make it right. Email us at azpeptidelab@gmail.com within 24 hours of delivery with the following: your order number, a description of the issue, and photo or video evidence of the problem. We review every claim individually. Valid issues β including damaged packaging, incorrect product, or a COA that does not match your order β will be resolved with a replacement shipment at no cost to you.
Do you offer bulk or wholesale pricing?
Yes. For bulk orders or institutional pricing, please contact us directly with your requirements and we’ll provide a custom quote. We work with universities, research labs, and independent researchers.
