if u wanna restore testosterone,
to youthfull levels, like u should, the supliment u need is called tribulus terestris, proven in clinical trials, to restore test levels to youthfull ranges,
best and popular, is called tribex,
and adrotest, u need to look for saponin and especially protodoscin content the higher the better,
these work by naturally stimulating the body to produce more test, compared with prescription test that just artificially provides the hormone, and actually may reduce natural test production over time, due to feedback loop
cheers
