Yes your diet is like 97% or something, not to get too technical. The supplements are the remaining 3 or so %. So the pills won't do anything if your diet isn't dialed in.
FWIW when I saw the name of this thread I thought this would be an interesting discussion of the differences between 1) a calorie deficit and training with HOT-ROX, or 2) a maintenance level cal diet or slightly reduced cal diet with Spike and training like a madman (as Spike generally amps this up). Personally I would choose #2.
