2,4,5-Trihydroxyamphetamine (THA) is a neurotoxin and a metabolite of MDMA. It comes from the ring-hydroxylation of 3,4-methylenedioxyamphetamine (MDA).
In one paper, it was shown to reduce hippocampal tryptophan hydroxylase activity by 54% after short-term treatment.[1] In another study, it was shown to significantly reduce striatal tyrosine hydroxylase activity.[2]
