Company details
Written by the company
Double R Labs is a research-driven peptide and performance-science company built on one simple promise: deliver clean, correctly-dosed, third-party tested products with speed, transparency, and real customer support. No games, no excuses. What makes us different is our mentality. We don’t act like some faceless warehouse pushing vials. We operate like a small, dedicated lab that cares about consistency, accuracy, and trust. Every batch is sourced from vetted manufacturers, verified through independent third-party testing, and paired with scannable QR codes so customers can confirm quality for themselves. We focus heavily on fulfillment speed. Orders placed before 2pm PST ship the same day, and customers who spend over $200 receive free UPS 2-Day Air. Our packaging, QC, and logistics systems are constantly being refined to make sure orders arrive fast, protected, and exactly as expected. Our community is a big part of what we do. We support lifters, athletes, biohackers, and everyday people who simply want reliable research materials without the nonsense this industry is known for. We stay active across multiple platforms, answer questions quickly, and take pride in giving customers a level of service that’s rare in the peptide space. If you want consistent quality, fast shipping, and a company that actually stands behind what it sells, you’re in the right place.
Same-Day Shipping on All Orders Placed Before 2pm PST
Free UPS 2-Day Air on orders over $200.
Order before 2pm PST and it ships today. Orders $200+ get free UPS 2-Day Air. We keep fulfillment tight so your research isn’t waiting around for packages.

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!
