Methane and sulfur compounds

Methane and sulfur compounds are stuff that comes out of your butt. It's basically a fart. The methane is the loud part of the fart, while the sulfur compounds are the stinky part. The more sulfur compounds it has, the stinkier the fart.

Ew! Who let out methane and sulfur compounds? It stinks! Stinky fart!

Methiopropamine 

Methiopropamine(MPA) is a stimulant structurally similar to methamphetamine, but with a thiophene ring instead of a benzene ring. The replacement of a thiophenyl group with a phenyl group means that MPA is 1/4 the strength of amphetamine and 1/6 the strength of methamphetamine. Unlike methamphetamine, amphetamine and methiopropamine are safe to use. Methiopropamine is safe long term.

I tried this methiopropamine and 7,8-Dihydroxyflavone combo. I was studying for hours! This MPA is great!
