    Free vs. Serum Testosterone

    Okay so I recently had some blood work done and found out that my free testosterone is at a 0.6 (range 0.0 - 2.2) but my serum levels are at 70 (range 8-48)!!! Free testosterone I thought is what accomplished the "muscle growth" and if I bring down my serum levels that it will allow for me to have more free testosterone.... Is this true? How do I free up more test by lowering my serum levels? Is this weird that I have this high of number naturally?

    Thanks!

    I believe free testosterone is active/not bound to SHBG. Serum is bound/inactive. Decreasing SHBG will increase free testosterone. It's hard to remember details sometimes.
    Hey, you guise.

    That is what I thought! So how can I decrease my SHBG?
