Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Your first step when receiving a positive result is to review your company policy to determine disciplinary action. Many policies call for immediate termination, some allow for the employee to seek assistance for the drug abuse problem. It is critical that you follow the policy to the letter and that your actions and decisions remain consistent from one employee to the next. Always provide your notification of the positive result and the appropriate consequences to the employee in writing. Depending on whether you have a DOT program, State Law Specific Program or non‐regulated program – there may be additional steps to take.
