Per4m Pre - 570g

Berry Blast, Blackberry, Blue Raspberry, Cherry Fizz — the flavour list on Per4m Pre reads like a pick'n'mix counter, and it runs further than those four; the variant picker holds the lot. The tub itself is 570g of pre-workout powder.

Mixed with water before a session, it follows the standard pre-workout routine, so the only real decision is the flavour. Per4m's sweet-shop styling has made the brand a familiar sight on UK gym shelves.
