Does tesamorelin show up on a drug test?
In sport, it can: growth hormone-releasing hormones, the class tesamorelin belongs to, are prohibited under World Anti-Doping Agency rules, and anti-doping labs test for them. The sources reviewed do not address standard workplace drug panels.
Short answer
In sport, it can: growth hormone-releasing hormones, the class tesamorelin belongs to, are prohibited under World Anti-Doping Agency rules, and anti-doping labs test for them. The sources reviewed do not address standard workplace drug panels.[1]
That study reports that these hormones can be detected in plasma with an immunoaffinity mass spectrometry method; it is a research-laboratory method, not a description of everyday drug screens.[1]
What anti-doping research has shown
Tesamorelin, under its brand name Egrifta, was one of the four compounds this detection method was built to find.[1]
A second anti-doping paper built a blood-screening method that co-extracts tesamorelin along with other banned peptides.[2]
That paper's real-sample demonstration used insulin analogues, not tesamorelin, so it shows the method works in principle rather than giving a detection window for tesamorelin.[2]
