XR® is an NSF Certified for Sport® amino acid supplement, independently tested to confirm it is free of banned substances, accurately labeled, and screened for contaminants.
In an industry where most products are never tested by anyone but the company selling them, NSF certification is the standard trusted by professional leagues, anti doping agencies, and the surgeons who formulated XR®.
Look for this mark on every XR® package
Xcelerated Recovery® carries the NSF Certified for Sport® mark, the leading independent certification for supplements in sport. Every batch of XR® is tested by NSF before it reaches you, not just once at launch.
That matters because XR® serves two groups who cannot afford uncertainty: drug tested athletes whose careers depend on a clean result, and surgical patients whose recovery depends on getting exactly what the label promises.
Our surgeon formulated amino acid blend was built for clinical use from day one. Certification was never optional for us. It is the baseline for any supplement recommended in an operating room or a training room.
The Certified for Sport® program tests finished products against three standards. A supplement only carries the mark while every batch keeps passing.
Tested against more than 290 substances banned by major athletic and anti doping organizations, including stimulants, steroids, and masking agents.
Contents are confirmed to match the label exactly. What is printed on an XR® packet is what is in the packet, at the stated dose.
Screened for unsafe levels of heavy metals, pesticides, and other contaminants, with ongoing audits of the manufacturing facility itself.
Certification is maintained through continuous testing. Any batch that fails loses the mark.
A contaminated supplement can end a season or a career, and athletes are held responsible for anything in their system. NSF certified supplements for sport are the only products many leagues and anti doping agencies consider safe to recommend. XR® gives competitors clinical grade recovery support without the risk.
Explore XR® for athletic performance
Recovery is a metabolic challenge, and precision matters. When a surgeon recommends a specific dose of amino acids, creatine, or HMB, label accuracy is a clinical requirement, not a nice to have. Certification confirms every XR® serving delivers the formulation your recovery plan is built on.

Under anti doping rules, athletes are strictly liable for any banned substance found in their system, even if it came from a contaminated supplement. Studies have repeatedly found unlisted ingredients in uncertified products. Choosing NSF certified supplements is the most reliable way for drug tested athletes to reduce that risk.
