if there was something to leave out, then albuterol would be the choice but i would definitely run s4 bro... in the sarms world, s4 would be comparable to winstrol... its going to give you the most muscle hardening and lean muscle... mk would act more like a tbol with the strength and a bit more size but s4 is definitely the most potent of the three... REGARDLESS, running either of those is going to require a mini pct... HcGenerate ES will be enough for the entire pct but it is going to be necessary bro...
