THE Pre-Thermo is our powerful pre-workout thermogenic blend, delivering a boost¹ exactly when you need it. Designed for the dedicated, this will ignite your workouts to new heights.

Our Packaging

We’ve gone through an exciting redesign, and as we step into a new era, you’ll see fresh packaging in your orders. Change is a good thing. But change takes time. Especially when you make change responsibly.

Because we don't believe in wasting perfectly good packaging — that would go against our sustainability pledge — you might get a mix of old and new designs inside your orders.

Rest assured, it’s still the same consistently high-quality product, just as you’d expect. If you happen to receive classic packaging, know that your order is helping to reduce waste. And if you receive anything with a fresh look, you’re one of the first, and we'd love to hear what you think. 
Thank you for joining us on our journey to reduce our impact on the planet, while maximising our impact for our community.

• Informed Choice certified
• With 200mg Caffeine per serving  to increase endurance¹
• 40mg of caloriburn and 25mg of Capsimax per serving
• 4g of L-citrulline and 2g of Beta-Alanine per serving

We know you need the right nutrition to fuel your workouts. That’s why unlike most pre-workouts we’ve added a thermogenic boost to help you achieve your goals. And to really maximize your efforts and really feel the ‘burn’, we’ve added 25mg of caspimax.

CapsiMax is a supplement of Capsaicin, a substance present in the plants of the family of Capsicum (red pepper, black pepper).

It also includes choline, a key diet ingredient that supports normal lipid metabolism² and homocysteine metabolism,³ and helps to maintain normal liver function.⁴

Alongside this, THE Pre-Thermo has got a powerful mix of caffeine, delivering 200mg of caffeine in each serving, which fuels your workout and helps you exercise for longer.¹

Informed Choice Certified
