Product Overview

Why did we design Thermopure?

Thermopure is a formula containing a host of ingredients to support a multiplicity of training goals. When you are working out, whether that be spinning at dawn or attending a gruelling cross-fit session after work, your body requires maximum energy, drive and focus to keep you achieving those all important goals.

How did we design Thermopure?

Ahead of the curve in innovation, Thermopure provides a unique combination of trusted and popular ingredients. With each serving, your body is provided with 5mg of vitamin B6, 21ug of vitamin B12, 120mcg of Chromium (as Chromium Picolinate), 150mg of caffeine, 375mg of Green Tea Extract, 200mg of L-Tyrosine, 125mg of L-Theanine and a touch of cayenne powder.

What are the Key Benefits?

  • 21 mcg of Vitamin B12 and 5mg of Vitamin B6 contain a variety of benefits. Not only will they contribute to the reduction of tiredness and fatigue throughout the day, and support normal energy-yielding metabolism, but will also support the normal function of your immune system.
  • 150mg of Caffeine (equivalent to 2 x small cappuccinos) may increase alertness and concentration.
  • Alongside aiding macronutrient metabolism, 120mcg of Chromium will support the maintenance of normal blood glucose levels.

Is this Product for me?

Thermopure is aimed at any male or female athlete, bodybuilder or sports enthusiast who is looking for a blend of key nutrients and minerals in an easy-to-consume capsule.

When should I consume Thermopure?

To reap the maximum benefits of Thermopure, we recommend consuming 1 serving (3 capsules) 45-60 minutes before your morning workout with a glass of water or juice. Alternatively, consume anytime throughout the day.

Please note that the labelling on this product is provided in English as a minimum. French, Italian, German, Spanish, Danish, Swedish and Finnish may also be present on a product by product basis.

Seems to work a bit

I take 3 pills on an empty stomach before a workout or 1 pill after a meal 3 times a week. Taking the pills before a workout seems to give me more energy for my workout. I am taking these with CLA and L Carnitine. Honestly I have lost a bit of weight but I also exercise at least 4 times a week. I did think the weight would drop off a lot more than this so I am wondering if I should be buying another bottle.

Spaced out

Took 3 tabs as suggested at 530am. Nothing really until about 830 when I started to feel a bit edgey and wired. Very conscious of how I felt over the next hour or so and felt overstimulated. Especially when there were a lot of people in the environment. Once training at 1100am the weird feelings started to subside but then for the rest of the day I just felt nauseous and weird with a banging headache.

I don’t like these. I use them as instructed but there is a downside. After taking these, leaving it 45 mins before workout, these make me feel sick and nauseous. I have a friend who recommended me to My Protein and their bundles but after discussing Thermopure with them, they have same side effects and we both agreed that we will not buy these again! They’re very hit and miss with effectiveness on my runs in the gym but that could be mindset. The sick and nauseous feelings can last whole workout.

They burn but also made me feel ill and anxious

They definitely increased my body temperature however, they also made me feel anxious and actually decreased my efficiency in the gym - they made me feel so ill I had to stop a work out and I found that they made me feel really anxious and headachy so if you have a tendency to suffer with anxiety (even though I dont usually) bear this in mind. I will be sticking to eating better and working out harder without the use of thermopure in future.

I have been taking to recommended dosage of these for over a week now and I feel no difference at all. Do not feel they give me that little bit of extra energy.

Good to use for boost before gym

I use this just before I leave the house to go to the gym. I find that it takes several minutes to boost my energy. Other reviews talk about it taking 30-45mins to have an energetic effect but I feel the effects quicker than that. I go to the gym for an hour or just a little more each time and find that I can stay strong all the way through even when lifting heavy weights.

Goes Well With:

Water or take it with your creatine supplement

I love these little bad boys! I'm not caffeine sensitive at all but I really feel when these kick in; you should know after you've taken them, you will feel when they 'burst', you'll get a warm sensation, for me it feels exactly like when I've eaten a jalapeño 15 minutes ago. Anyway, overall yes I'd recommend them.

Goes Well With:

Before any workout, with water and BCAA's
