I doubt it, unless you're tested for some high level government job, you should be fine. SARMS are not mild altering, they are used for performance enhancement purposes only. So, if this is a regular blood test, likely it's going to test for recreational drugs like cocaine, marijuana, heroin, pain killers and so on. Unlikely that you would be tested for steroids or sarms. Though maybe you should check with your work and see the list of banned substances.
