7,8-Dihydroxyflavone

7,8-dihydroxyflavone (Tropoflavin) is a supplement that is an antioxidant. It has also been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). In addition, tropoflavin possesses powerful antioxidant activity independent of its actions on the TrkB receptor, and protects against glutamate-induced excitotoxicity, 6-hydroxydopamine-induced dopaminergic neurotoxicity,28 and oxidative stress-induced genotoxicity. It was also found to block methamphetamine-induced dopaminergic neurotoxicity, an effect which, in contrast to the preceding, was found to be TrkB-dependent. 7,8-dihydroxyflavone protects against stimulant induced glutamate exitotoxicity and dopaminergic neurotoxicity. By stacking amphetamine or other stimulants with Tropoflavin, you can prevent brain damage. However, you can't prevent cardiotoxicity. So choose a less cardiotoxic stimulant like amphetamine, Ritalin, caffeine, or EthylAmphetamine, or Modafinil, the wakefulness enhancer, instead of choosing more cardiotoxic stimulants like crack. Crack is wack, speed(amphetamine, EthylAmphetamine) will help me succeed
I stacked 25mg EthylAmphetamine with 25mg 7,8-Dihydroxyflavone and I prevented brain damage. Tropoflavin is awesome!
