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.**

We’re sorry to hear you were disappointed. At Double R Labs, we take quality control and transparency seriously. Our research products are backed by batch-specific third-party testing, and those results are made available directly on our website for customers to review.
As all products are sold strictly for research use only, we cannot comment on personal outcomes or expected “effects.” That said, if there was any issue with your order, batch, or product received, we’d absolutely like the opportunity to review it.
Please contact us directly with your order number so we can verify the order details and address any legitimate concern appropriately.

I did not receive the orderGood morning
Good morning. I still haven’t receive my order since January. I need to resolve the problem
January 23, 2026
Reply from Doublerlabs
Good morning Carla,
We’re sorry to hear you haven’t received your package. We were first notified of the issue via email shortly before this review was posted and were not previously aware of any delivery problem.
According to UPS tracking:
• 1/23 – Order shipped same day and handed to UPS
• 1/25 – Delay due to weather
• 1/31 – Last scan in Miami
At this time, it appears the delay occurred with the carrier after the package left our facility.
We absolutely want to resolve this for you. If the package has been lost in transit, we are more than willing to assist with a replacement or appropriate resolution. Please check your email so we can move forward quickly and get this taken care of.
We stand behind our customers and will make this right.
— Double R Labs
Quick Shipping, Fantastic Customer Service
