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.

Will buy again !

Awesome company product came as expected, and they went above and beyond for me on shipping. The post office messed up and sent my purchase back to them and they sent it back to me and covered shipping the second time. Will be buying again!

Very competitive pricing

Very competitive pricing. Best price in the area of San Diego. Love the transparency and the extensive test of the products. Know the purity of the product is a big plus when coming to your overall health and wellness.

I’ve had a great experience with Double…

I’ve had a great experience with Double R Labs so far. Customer service has been excellent — responsive, helpful, and willing to quickly resolve issues when they arise. I recently reached out regarding a shipping concern and Rob handled it immediately, which I really appreciated.

Shipping has been fast, prices are fair, and the products have been high quality and consistent in my experience. Everything has arrived well packaged and exactly as expected.

It’s refreshing to deal with a company that values both product quality and customer satisfaction. I’ll definitely continue ordering from Double R Labs and would recommend them to others looking for a reliable research peptide source.

Total scam

Total scam, you’re better off buying stuff from Amazon or somewhere else. I felt no effects at all!

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.

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.

Hi Gabriela,
Thank you for your feedback , I’m sorry you were disappointed. For clarity, our products are research-use compounds and not FDA-approved medications. effects can vary significantly between each test subject and are not guaranteed. Also, many researchers report that noticeable appetite-related effects may take several weeks up to 4-6 depending on protocol and dosing. Not just in 1-2 weeks as you stated in your email. Sensation doesn't always equal causation.
If you’d like, please reach out to our support team and we can help verify your reconstitution and dosing calculations to ensure everything was prepared correctly. This is where many researchers fall short and under dose their subjects.

Thank you and have a bless day.
Rob, Double R Labs
