I am over at elitefitness debating an owner of a supplement company about tribulus. Here is what he had to say…
"actually tribulus does increase libido and erections, but not because it stimulates LH or testosterone production. Those effects are related to dopaminergic, NO and oestrogenic effects.
tribulus is not useless, its just does not do what it claims (raise LH and testosterone)- though it has effects that would lead one to beleive (incorrectly) that it does."
Anyone please feel free to chime in and give me an in-depth scientific explanation of exactly how tribulus works.
