[QUOTE="xqfq, post: 191471, member: 38167"] I looked into this figure some time ago and wasn't able to verify it. The statement above is from a column in what is akin to a magazine, not a journal, and doesn't have a source attached to it. Digging into the literature, I was unable to find a study or paper that quantified the amount of testosterone in milligrams released in the average male. Without further elucidation, I would guess this figure is not a direct measurement of testosterone released in milligrams from the testicles, but is instead an approximation based on serum levels. If such a figure is an approximation based on serum levels, then using it to reason about the relationship between injected testosterone and serum levels would be potentially unreliable. As a hypothetical, imagine some men metabolize testosterone much faster than others. Imagine their testicles produce 10mg a day of testosterone. When their serum testosterone is measured at its AM peak, it is 400 ng/dL. If some kind of direct measurement of testicular production of testosterone was used, then the man would be recorded as having 10mg/day of production; if an approximation based on serum levels was used, he might be recorded as having 4mg/day of production. I hope this example makes sense. [/QUOTE]
