All terrible. I just down them as quick as I can. And measure all liquids in "shots". Parachuting is one of the best ROA's for most substances.
Edit: I mean minus things that are tasteless/near tasteless. But even, then it's a strange sensation and I need to take it down quick.
I guess Vanilla or Choco Whey is pretty nice with water or almond milk.
And old PES(Performance Enhancement Science) products like Alphamine (now just an energy drink rather than a true thermogenic powder). Those were hard to get in Canada and much of europe, but now they're just not good. They're other stuff is good tho still, I think.
