Very good mixing and definitely will be getting it again
I bought this order to take back to the Philippines as I have followed the brand for a while on social media. I can’t wait to fly back on Friday and try these products.
All of the products I have ordered have been great taste and do what they say on the tin
Quality texture and taste
Great product Mixes very well and taste brilliant No digestive issues at all as well Rob is a great help and the company is brilliant
Nice flavour and very easy to make
Texture is really good but flavour not great, not really any flavour at all not getting any white chocolate or biscoff

Arrived in less than 24 hours, flavour and quality is immense!! Yet again GAS MARK 10 don’t fail to deliver
Perfect product quick delivery… less than 24 hoirs received
Unbelievable. Easy to mix brilliant flavour. Just like all other products all top notch . Highly recommended
The taste is inedible - a very distinctive manufactured taste - not pleasent at all , very disappointed nothing like white chocolate or biscuit
Great products
Could be a little more tasteful. Find it a little bland. The carrot cake iso blend in with it makes up for it though
Another top flavor the taste is proper 10/10
Amazing product nice taste
Best COR ever, I always use this no clumping smoothest ever and order direct it next day what’s not to love
Lovely mixed with vanilla ice cream iso
Great taste, easy mixing. Top quality
Initially i found this product way too sweet, and was at first disappointed. However, using approximately 200ml of water per scoop helped reduce the flavouring substantially. If you add more water to powder ratio, you can reduce the taste but still get a somilar consistency. Overall great customer service and great value for money. Would buy again.
Taste incredible
Value for money !
Best on the market
Game changer
Great taste, great texture!
Bang on
