How long does it take synthetic testosterone to get out of your system?

Testosterone is always in the body whether you're male or female. Female naturally have less, well a lot less. However, if you are referring to taking anabolic substances and having more than normal, It can be up to a month. They do not typically test for anabolic use in normal people since it is extremely expensive to test for and it is hard to tell the difference in the normal amount and the extra amount you may have taken through other means. I would not worry about it unless you are a major athlete and people suspect that you are using anabolic substances. Even if you are, It is still hard to prove and near impossible to tell even with a test and quite expensive. Hope this answers your question pretty well. Good luck, have Fun, and stay safe ;)
