problem is real testosterone boosters are either
1. herbal and thus untested...may work, may not work, or may aromatize to estrogen
2. aren't herbal, and therefore don't work, because the FDA banned anything that did, because you can't really play around with your hormone levels without a doctors supervision.
if you want some test, go see your doctor. you may have above normal test levels to start with.
too much test. is a bad bad thing.
