vet do u think most people loses there natural test production after taking steroids for years? i kno a couple guys who are maintaining pretty good natural test levels and there in their 30's..
Like I said before, I think its highly variable.
I spent some time in college doing reasearch on environmental estrogens---particularly bisphenol and pesticides. The frequence of those hormone mimickers exposure to people now days makes me think that ALL men age 35 or over should have their hormone levels tested. I think they should do it every 3-5 years after the age of 35 too. Just because someone is fine at the age of 31 doesn't mean they'll be fine at the age of 36.
