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.

Used for weight loss

Not sure as a pre-workout sup like some reviewers have mentioned as I have only taken this for weight loss. I havent changed my diet or done more cardio (not got the time to do even more!) so these must be the cause for the improved weight loss. I have noticed some days that I get a little heart burn and a few extra toilet breaks for a pitstop but I would say these are working a treat as I am hurtling towards my goal weight again.

These capsules work so well if you do as the instructions say! Even taking them for 3 weeks now, if you train like an athlete and put all the hard work in you’ll see results... lost 3 inches from my waist and nearly 8kg of weight, so happy with the results, can now switch from the capsules to BCAA! Thanks MyProtein

Goes Well With:

Green tea

Changed formula!

Used to be the best on the market but they’ve changed the formula and removed the raspberry ketones which makes a massive difference for the worse. Myprotein Please return this to the old formula.

Formula has changed Beware!!!

The old thermopure was in my opinion one of the best pre-work out pills for energy and concentration. Unfortunately it seems they have decided to cut corners and have removed two ingredients from the original formula. The American ginseng and Raspberry leaf extract has been taken out and it makes a HUGE difference. They have also upped the dose of caffeine hoping that no one will notice in order to counteract the lack of these two ingredients and it's quite a spectacular failure. Myprotein fix this please and go back to your regular formula, please.

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.
