Thermogenic Protein for Weight Loss

Thermowhey has been formulated based on cutting edge scientific literature. Combining the most bioavailable and pure Whey Protein Isolate with Micellar Casein (Milk Protein Isolate), the combinations of proteins in Thermowhey, ensure fats and carbohydrates are minimised. The addition of Casein means absorption is prolonged, which is vital for the feeling of fullness.

Amazing flavours

Thermowhey comes in 6 rich flavours that feel like a treat when really, they're as healthy as can be!

  • Chocolate - a creamy chocolate flavour. Truly a classic.
  • Cookies and Cream - a sweet blend of vanilla and cookies.
  • Strawberry - Thermowhey's fruity flavour.
  • Salted Caramel - the perfect blend of sweet and salt, with oodles of caramel.
  • Rocky Road - amazing combination of marshmallow, chocolate and strawberry.
  • Vanilla - a clean, crisp vanilla and nothing else.

An optimum blend of WPI and Casein

By combining Whey Protein Isolate and Casein, we feel that Thermowhey offers the vital benefits of both proteins, which together are more effective than either protein source in isolation. Thermowhey is more than 83% protein, yet contains less than 1g of fats and carbs per 30g serve. Thermowhey combines 9 key ingredients, Glucommanan Fibre, Forksolin, Sesamin, ALA, Green Tea Extract, Olive Leaf Extract, Cayenne Pepper Extract and Caffeine have been included at doses supported by literature, and should ensure body composition and performance goals are met.

Clinically tested ingredients

The ingredients selected for Thermowhey have all been used in clinical trials and have been included in doses which we deem effective for the purpose. It is important to note that Thermowhey is not simply a fat burning protein with fashionable ingredients, rather a very carefully formulated product which can assist those looking for real body composition changes.

Thermowhey is suitable for both men and women, regardless of body composition goals.

    Thermowhey Protein Salted Caramel

    Posted by Keeni on Nov 10, 2018

    I usually use the Salted Caramel Protein Matrix, but decided on trying the Thermowhey in the same flavour. It tastes slightly different, but not in a bad or good way, just slightly different from the Matrix...still an amazing protein that I love!

    Not too shabby

    Posted by Phil on Nov 09, 2018

    Good product! The taste is not great compared to the WPI, so make sure you mix with at least 400ml of water to dilute the flavour. I would definitely purchase again. Lost one star because of the flavour.

    Quality and taste

    Posted by Diego Quevedo on Nov 07, 2018

    I have been taking supplements for years but never have I seen supplements so cheap and great tasting since I started buying from bulk nutrients.
    This protein powder is excellent in taste, high in Protein and low in Carbohydrates. What more do you want? Oh yeh and also has fat burning ingredients added too.

    I bought 5kg and I will re buy everytime. Highly recommended

    Flavour and Texture is the let down

    Posted by Tara on Nov 07, 2018

    This was my 2nd purchase from Bulk nutrients. First time I ordered the Whey Protein Isolate and decided to try the Thermo Whey 2nd time around. So far I prefer the Whey Protein Isolate as the Thermowhey is slightly grainy and flavour isn't as good. I bought the chocolate so not sure what the others are like. So far preference is the WPI. Love that the shipping comes so quickly.

    ThermoWhey Protein Mix

    Posted by Satyaki on Oct 22, 2018

    I have been using ThermoWhey for sometime and have found this protein mix to be really good amongst some of the other thermogenic protein mixes in the market. The taste is quite good and it mixes really well. Along with a controlled diet and workout routine, I have found this product to assist in weightloss. The product is good value for money and would definitely recommend giving this product a go.

    Great flavour and mixes really well. The Rocky Road is by far my favourite flavour at the moment!

    The best

    Posted by Deborah Kallu on Oct 21, 2018

    I don’t think a bad product can come from Bulk Nutrients. I’ve tried the protein matrix which I loved, but switched to the thermowhey to try and shred down a touch more. No bloating, tastes great (I have it in a breakfast smoothie or just with water if I train in the evening). Quality product!
