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.

Turned to gel, no response from company
I ordered 3 vials of Tesamorelin (ive used this peptide for a while from various sources), they were shipped quickly and packaged well, however the first vial turned into a thick gel, ive never seen this before with any other Tesa. The main thing is, i reached out to them and got no response.

Hi Brad,
We did respond and offered to resolve this for you by email, a day later, on Nov 26/2025.
I explained that we keep replacement inventory on hand specifically for situations like this, and asked you to reconstitute one additional vial so we could determine whether the issue was isolated or affected the rest. I also made it clear that if another vial behaved the same way, we would replace or credit the product.
We never received a reply letting us know how you wanted to proceed.
Let us know how you would like to proceed so we can resolve the issue.
