@tutu42 Welcome to Mayo Clinic Connect. You are wondering if there are good over the counter supplements for low testosterone.

You will notice that I moved your question to a previous discussion related to this topic. Active members of the Men's Health group like @abbas @phoenix1647 @glenner075 @jimhd @jakedduck1 may be able to offer suggestions and/or support.

Below I have linked two Mayo Clinic resources related to the topic of testosterone that @johnbishop was kind enough to pass along.
– Testosterone Therapy https://connect.mayoclinic.org/page/mens-health-1/newsfeed-post/testosterone-therapy/
– Video Q&A about The Truth about Testosterone and Men’s Health https://connect.mayoclinic.org/webinar/facebook-live-the-truth-about-testosterone-and-mens-health-with-dr/

May I ask if you have been diagnosed with low testosterone and if you have considered a prescription medication, if appropriate?
