Sorry, but Post Cycle Support doesn't combat cortisol. It regulates estrogen and boosts test.
I do know what you're talking about as far as the cortisol/stim/caffeine correlation though. I remember reading about that when I first signed up here at AM. You should be back close to your baseline by now, but if you're concerned, then check out cort blockers at NP. Check out Lean Xtreme, Lean FX, X-Lean, Suppress C, Endoamp, etc.
EDIT: Wait, doesn't Recreate work against cortisol?
And on a side note, be careful to not cut too soon after bulking up. I'm not sure what kind of cycle you just had, but I know from experience that cutting out too many calories shortly after a cycle is an easy way to lose those newly earned gains
