Stim Reaper contains four stimulants that increase energy and improve concentration and can also assist fat loss. Power through your workouts no matter how tired you are or if food is low on a diet!

With a high caffeine content of 400mg per scoop, we'd not recommend using this after mid-afternoon as it may interrupt sleep. Save for your most challenging sessions such as a big leg day!

For experienced pre-workout users who are looking for something super strong to use as a tool when most needed.

Killer Labz Stim Reaper Pre-Workout contains 6 ingredients to support energy, focus and fat burning. The innovative formula contains:

Caffeine anhydrous (400mg) – the most popular stimulant, here in a pretty heavy dose, we challenge you not to destroy a workout after this!

Beta-alanine (3g) – beta alanine helps buffer lactic acid so you can avoid muscular fatigue and get those all important last few reps!

Eria Jarensis (250mg) – a stimulant which increases mood and energy by increasing the levels of dopamine and nor-adrenaline in the body for an almost euphoric effect.

Rauwolfia Vomitoria (2mg) – increases energy and aggression through raising adrenaline and can support stubborn fat loss through mobilisation of fatty acids in the mitochondria.
