Ya, I thought the theory was that a deeper sleep allows your body to produce the testosterone it needs.

It has been shown too increase prolactin in humans. I havent seen any studies regarding testosterone, and humans, for what its worth.

0.5mg/kg = 50mg for a 220lb person. Huge dosage, although I'm not sure how to translate the rat dosage into human terms.

I've never heard about it inhibiting Testosterone, I've usied it in a blend (Scivation Knockout) and I haven't noticed any regression in the gym or in the bedroom.
I know it does promote REM Sleep and to release Growth Hormone.
I've heard about people using it for Pre Workout to spike GH, but I haven't tried it myself.

so this study is based on doses given to rats that equal 50mg to people? that is 10x what a sane person would take, where is the relevance?

I take 1mg before bed so I don't think I have to worry about this.
BTW, experiments on humans have been done with 6 GRAMS of melatonin with no signs of toxicity.

The amount of testosterone secretion inhibition it would cause would be so minimal it would be much more worth taking melatonin for added sleep/energy that your testosterone levels would actually go up.

I think this can help:
the way I see it is that a 0.5mg/kg on a 80kg human its equivalent to 40mg of melatonin so ...
a guy that takes 4mg /day will be taking 0,05mg/kg, a lot less than the study dosage,if it still inhibits test , well that I don't know but its unlikely
