Kryptonite may be hazardous for Superman, but for humans, it is a 100% legal energy pill that will turn you into a steely hero of the dance-floor (or whatever playground you choose for rhythmic moves) for 4-7 hours. The unique composition of plant extracts and vitamins induces an “E”-like high, so don’t underestimate these pills and take no more than 1 per day. Content: 6 capsules.
