Best no-stim PreWorkout while on Daves Diet

[Sensei]

Ive been on daves diet since the new year started, I'm leaning out just fine. Ive been using preworkouts w/ no carbs like ALR's WTF pumped & VPX NO Shotgun. But I'm seeing if anyone here has good expericences w/ no-stim/caffiene free Preworkout products. I'm considering VPX NO Snythesize(all calories coming from Protein) or Millenium Sports Caffiene Free Ragnarok which has no calories at all. Any input is appreciated

vpx no synthesize is incredible. seems to be the same as shotgun but without the stim. so there should be no reason not to take it preworkout. well at least mix a serving with 24 oz or more of water and drink a third of it before you workout. im doing that right now and taking gaspari plasmajet. thats a crazy stack though people might say its redundant.
