Sports Technology Labs is a US-based research supplier headquartered in Shelton, Connecticut, best known for supplying research-grade peptides and SARMs to businesses, institutions, and independent researchers. Every product is designated strictly for laboratory and research use — not for human consumption — and the company has built its reputation on doing the unglamorous quality-control work that many "marketing-first" vendors skip.
Their testing story is genuinely strong. Products are bottled in the USA and sent to accredited American third-party laboratories for High-Performance Liquid Chromatography (HPLC) testing to a minimum stated purity, and — critically — they publish COAs that include the testing lab's contact information so you can actually verify the certificate is real, rather than redacting it the way some vendors do. They also make a point of using USP-grade PEG-400 as a carrier and eco-friendly glass bottles with fixed glass droppers, which avoids the plasticizer, leaching, and contamination problems that come with cheap plastic bottles and external plastic tools. Rounding it out: transparent, legal payment processing (domestic credit cards plus crypto), fast US shipping, and a 60-day money-back guarantee that's rare in this category.

Short answer, based on our review criteria: yes — Sports Technology Labs is a legitimate, well-established US research supplier, and one of the more transparent operations we've reviewed. Here's what stands behind that:
A few honest things to know before ordering: Sports Tech Labs is SARMs-first — its peptide line is solid and third-party tested, but narrower than a dedicated peptide house, so if you need an exotic or GLP-class compound, check the catalog first. Their headline 98% purity figure is stated for the SARMs line; peptides are verified via the same accredited third-party labs. And as always, everything is strictly for in-vitro research use only — not for human or animal consumption. None of that is unusual for this space.
