One caution that I have is that I tried for years to raise my testosterone through lifestyle changes, . diet, sleep, supplements, etc., and nothing budged my testosterone. And I see this quite often on The Peak Testosterone Forum : some men seem to have actual damage to some part of their HPT (hypothalamus, pituitary and testes) axis. In those cases, going natural just does not work for reasons that we do no understand yet. Of course, it does not hurt to try, and I especially encourage the younger men to do that.
