Tryptophan Lowers T Levels

I have a few questions as the study is a bit over my head so it’d be great if Bushido, Bill Roberts, Kman or from that league could chime in:

  1. Is it reasonable to assume that the same effects could be observed in humans?
  2. Any way to counteract the T lowering effects described in the study?
  3. Is a low dose of melatonin (1mg) going to have similar effects?

I do like my tryptophan but I don’t want sth to decreasing my T levels as I am already borderline low now. I wonder if tryptophan is to blame…
