[Star Wars] Do Sith ever use performance enhancing drugs like amphetamines, steroids, etc?

I was thinking because of the way Darth Maul was bisected to maintain his physical prowess he might be reliant on hormone supplements for the rest of his life, seeing how he was effectively castrated; but if someone like Maul would be making a point to use medicines to keep his testosterone levels high it would makes sense that he would use other kinds of drugs too; maybe not things that would turn him into a junkie like spice but combat stims or things like that maybe? Is that ever talked about in the lore?

The philosophy of the sith dictates power must be your own. A true sith master will sends their apprentice to a monster infested hell-hole to train them because if they survive it will have been through rhe apprentice's own strength. Drugs do not fall under this category as it is the "cheat" method and thus is not beneficial. 

Maybe after developing and becoming self-sufficient one or two sith may use some form of physical enhancement but generally no.
