Company details
Written by the company
Double R Labs is a research supply company committed to quality, transparency, and customer satisfaction. At DRL, every batch undergoes our comprehensive 8-Point Quality Assurance Protocol before it is approved for release. We believe quality should never be assumed—it should be verified. Our 8-Point Quality Assurance Protocol includes: • Identity Testing • Purity Testing (HPLC Analysis) • Content Testing • Sterility Testing • Endotoxin Testing • Heavy Metal Screening • Fentanyl Screening • 4X Conformity Verification Our 4X Conformity Verification process ensures that product specifications, labeling, documentation, batch records, and release requirements are reviewed and verified before a product is approved for release. We do not sell products until all required testing and verification procedures have been completed and reviewed. We also do not offer pre-orders or backorders—if a product is available for purchase, it has completed our quality assurance process and is in stock. This approach reflects our commitment to quality, consistency, and confidence in every batch we release. If a batch does not meet our standards, it does not reach our shelves. We continue to invest in improving the customer experience. Orders placed by **4:00 PM PST Monday through Friday** and **2:00 PM PST on Saturday** qualify for same-day shipping. Customers also receive complimentary BAC Water on qualifying orders of **$250 or more** and **free shipping on qualifying orders of $300 or more**. Our goal is simple: provide high-quality research materials backed by transparency, responsive customer support, and a commitment to doing things the right way—even when it takes longer or costs more. At DRL, we believe trust is earned through consistency, communication, and accountability. Every batch is tested, every result is reviewed, and every release is verified before reaching our customers. Thank you for supporting DRL and being part of our continued growth. **Research = Results.**

Great customer service and response time
Made another purchase with DoubleRLabs today.
Price was great and so was the service. Sometimes I go through the Peptide Price Tool that links to the website. This was is pretty glitchy and kicks me out of the website fairly often which actually creates multiple invoices that I receive multiple recipes for. I emailed theDoubleR and we figured out what the issue was and it was corrected right away. I just hope that they keep conducting business the way they are.

Peptides protected and fast shipping
I placed an order and it was processed and shipped out the same day. I received it in 2 days and was updated throughout the whole process from order received to delivered to me. Peptides were packed carefully and securely with no damage. Cap tops were sealed and intact, puck was whole, and the vial was bubble wrapped and shipped in a black envelope to protect from any degrading. Prices are great. Super happy with this company. I have already recommended them to others and will continue to do so!
