An RC is a Research Chemical. Some research Chemicals get you high, or help you study at low doses (4F-MPH, a-PVP, Methcathinone). Some are milder and help you study with energy (Prolintane,

Methiopropamine, Ethiopropamine, Cathinone). Some research chemicals help you study (Phenylpiracetam Hydrazide, N-Acetyl-Selank, Selank, Semax). Some can cure depression permanently (NSI-189, 9-Me-BC). Some RCs can help you stay awake and remember stuff (Hydrafinil, Adrafinil, Fladrafinil, Flodafinil). Some RCs raise your mood by preventing breakdown of Dopamine and Norepinephrine (D,L-Deprenyl; Pheniprazine). Some are NDRIs (Thiopropamine, PhenylPropylAminoPentane). Some are histaminergic to help you wake up (Wakix, Sunosi, Modafini, Armodafinil, Flmodafinil, Fluorenol). Some RCs became medicine and can help with trauma to help you forget (Propranolol, Klonopin). Some are replacements for alcohol/ethanol (2-methyl-2-butanol, Bretazenyl). Some are empathogen-entatcogens (IndanylAminoPropane (IAP), IndanylMethylAminoPropane (IMAP)).

Warning /!\: The long term effects of research chemicals have not been studied.
Tony: I took 100mg of Flodafinil and stayed up for 12 hours straight. I was studying.

The next day, I took 30mg Ethiopropamine (EPA) and 100mg Phenylpiracetam Hydrazide and studied and cleaned my room for 6 hours. Thanks RC!
