Product Description

No matter your goal, we've got a stack to suit you! Wanting to shred some extra fat? Keep reading.

The F45 Challenge Fat Loss Stack contains:

To optimise your fat loss results, we recommend the following:

  • 1 scoop of Oxyshred either 15 minutes before training or first thing in the morning on an empty stomach if you are training in the afternoon/evening
  • 1-2 scoops of glutamine before training (can be stacked with Oxyshred)
  • 1 scoop of protein post-training

Why these products?

Oxyshred is a potent thermogenic fat burner. It works by inducing hyper-lipolysis which is a complex process of super-efficient and ehanced burning of the subcutaneous fat molecules. This means it will maximise your results when paired with proper nutrition and exercise. Plus, when taken before training, it will give you a boost of energy to push yourself even harder. 

Glutamine is the most abundant amino acid in your body, but it reduces with stress (emotional and physical). It preserves the architecture of the muscle tissue and prevents the skeletal musccle being broken down for energy. With high intensity training like F45, supplementing glutamine is recommended. Taking 3-5g per day has been shown to support immunity, enhance recovery, boost lean muscle gain, and support healthy gut function.

Protein is the most important nutrient for weight loss. A lot of people struggle to consume a sufficient amount of protein each day, so a shake is a useful tool to boost this. A high protein diet helps to build lean muscle when combined with exercise. This then works to boost your metabolism and burn more calories, leading to weight loss. It can also help to reduce your appetite.

10/10 Double Rich Chocolate

A powder that tastes good with both milk and water. Been using the same whey daily for a couple of years now and still enjoy drinking it.
Doesn't give me the tingles like other products, flavor is good no fake after taste
Flavour is amazing and good quality of protein

10/10 French Vanilla

Had a great taste has helped me get a great recovery I have found that when I use it the after a workout I wake up the next day feeling way less sore then I usually would.

10/10 Passion Fruit

Such a good pre-workout felt super energised during all my work outs and so easy to take with water. Flavour is a bonus!
Great flavour, no complaints
I am currently consuming this protein. I am very satisfied with the quality, price offered by this brand. The protein tastes delicious, you can mix it with milk or water and it will still taste delicious. I have seen my muscle gains increase since switching to Whey and I plan to continue with this brand on my journey to transform my body and improve my lifestyle.
