Naughty Boy Menace Pre-Workout 390g | 30 Servings

Naughty Boy Menace is a high-stimulant pre-workout powder built around a fully transparent label — every ingredient is disclosed at its exact dose, with no proprietary blends. Each 390g tub provides 30 full servings, and it is one of the most heavily dosed pre-workouts we stock.

What's in a serving

Menace uses full, clearly stated doses rather than hidden blends, so you know precisely what you are taking before you train:

  • Vegan fermented L-citrulline — 4g
  • Beta-alanine — 3.2g (the ingredient responsible for the familiar tingling sensation)
  • GlycerSize glycerol — 2g
  • Caffeine — 350mg
  • Alpha-GPC (AlphaZone) — 600mg
  • Juglans regia — 300mg
  • Biophytum — 150mg
  • AstraGin — 50mg

Who is Menace for?

With 350mg of caffeine per serving, Menace sits firmly at the high-stimulant end of the market and is intended for experienced pre-workout users with an established caffeine tolerance. If you are new to pre-workout, start with half a scoop to assess how you respond, or choose a lower-stimulant option from our caffeine-free pre-workout range.

How much caffeine is in Naughty Boy Menace?

One full scoop provides 350mg of caffeine — roughly the equivalent of three to four cups of coffee. Do not exceed one serving in 24 hours, and avoid other sources of caffeine on training days.

Does Menace clump in the tub?

Some clumping is normal. The formula contains glycerol, which naturally draws in moisture. It does not affect the product in any way — simply break up any clumps before measuring your scoop.

Choosing a flavour

Menace is available in six flavours, all at the same full dosage. Browse the rest of our pre-workout collection if you would like to compare stimulant levels across brands.
