Your questions, answered

Clear answers before you choose.

What does Per4m PUMP do?

It's a stimulant-free pre-workout that supports hydration, muscle pumps and focus without any caffeine — good for evening sessions or anyone sensitive to stims.

How do I take it?

Mix one scoop (16.5g) with 200–300ml of cold water, 15–30 minutes before training. For an extra pump, add a scoop of the included Glycersize too.

How many servings are in the tub?

30 servings at 16.5g each from the 495g tub, plus a separate 90g pouch of Glycersize.

What's the key ingredient behind the "pump"?

10g of L-Citrulline per serving, which raises nitric oxide levels and boosts blood flow to working muscles.

Does it contain caffeine or allergens?

No caffeine and no stimulants. It doesn't contain allergens directly, but is made in a facility that also handles milk, soy, gluten, egg and nuts.

What is Glycersize and why is it separate?

Glycersize is a glycerol-based hydration ingredient that draws extra water into your muscles for a fuller pump. It comes as its own 90g pouch so you can add it in when you want maximum effect, rather than it being locked into every scoop.

Can I take this with a caffeinated pre-workout?

Yes — because PUMP is completely stim-free, it stacks well with a caffeinated pre-workout without doubling up on stimulants.

What flavours does it come in?

Options include Blackberry, Cherry Fizz and Peach Sweets, alongside other flavours in the range.
