    Wild ride! Went from 120mg > 100mg > 80mg > 90mg. T is higher at 90mg 3x a week than 100mg 2x a week

    At one time. I injected 100 mg of testosterone twice a week with 500 IU of HCG twice a week. I did feel my best on that protocol. My sleep and and anxiety were both good. No issues. I just could not control my HCT so I lowered my dose and now I inject 16 mg daily and 500 IU of HCG every third day.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
