Choose the labeled amount per unit and quantity before comparing. A single unit and a multipack have different upfront prices. Keep product format and exact recipe consistent; similar names do not establish equivalent products.
Follow the original listing to check its quantity, availability and current price. Unit prices use the full labeled mass in each selection.

9-Me-BC (9-methyl-beta-carboline, 9-methylnorharmane) is a small synthetic beta-carboline, a class of pyridoindole compounds that also occurs in cooked food, tobacco smoke and the human body. Most methylated beta-carbolines damage dopamine neurons, but German research groups in Berlin, Dresden and Jena reported between 2008 and 2020 that the 9-methyl isomer instead stimulates tyrosine hydroxylase expression, raises neurotrophic factor expression, inhibits monoamine oxidase A and B and restored dopamine neuron counts in a rat toxin model. It is sold online as a nootropic for so-called dopamine repair, but it has never been tested in humans, has no pharmacokinetic or safety data in people and holds no regulatory approval anywhere.
