For clarification, I'm not referring to things like surge, spike, prohormones, stimulants, etc...I'm referring to those things that are more along the lines of fish oils, vitamin D, etc. What are the ones that you consider VITAL...where you tell someone "you don't supplement with X, why not??"
Obviously Flameout(or other fish oils, I guess) should be there, Vitamin D seems to be pretty big these days, I'm reading more about Vitamin K and apple cider vinegar in a number of places. What other supps do you guys swear by?
Thanks for the responses
