A decent dose of caffeine won't cause any extra problem. If your BP gets that high you have serious issues.

Anyone use preworkouts while on cycle? or is the added blood pressure increase not a good idea

good to know....any personal favourites? ive tried pretty much everything. Jack3d seems to be the best for me
i use a pre all the time...i feel the best is to just try out as many as possible. a lot of the off label brands are sick!
