If the recreate does not stim you much or at all, then I think it would be ok to mix the two. are you talking about tight hardcore or Blaze Xtreme (blaze xtreme has a little tta and some 7 keto I believe), which would compliment recreate well, but Tight Hardcore looks stronger stimulant wise and if that is the one you should add it slowly(start with 1 cap added to the Recreate first). Maybe someone else has better advice. good luck
