This is the stim-free half of Per4m's pre-workout pairing: pump and hydration without the caffeine. The Glycersize angle is about drawing water into the muscle, which makes the 495g tub a favourite for evening training and high-volume sessions. Six flavours, from Blackberry to Strawberry Blackcurrant, keep it from feeling like a chore. We stock it because Per4m is an anchor brand for us and because plenty of customers want the pre-workout ritual without the stimulant bill. It also stacks cleanly on top of a caffeinated pre if you want both.

How to use
Mix one serving with plenty of cold water 20–30 minutes before training — hydration helps the formula do its job. Caffeine-free, so late sessions are fine. Stack it with a stim pre-workout on days you want the full package.
