these things are an essential amino acid that is a precursor to dopamine&norepinephrine among other things...http://en.wikipedia.org/wiki/Phenylalanine ..so shouldnt this help people after rolling??? I just got over a long cycle of ecstasy abuse... I was taking 5-htp which restored my seritonin but I think my dopamine and norepinehrine levels were still low as fuck becuase once i started taking these its like ahhhhhhh relief .... these things are awesome..they are all natural and helped me alot...just putting it out there
