29g per 100g of protein powder!

29g per 100g of protein powder! This really should be advertised somewhere, it makes it look like its 29g per scoop but nope, your going to need 3 and half scoops to reach this amount. If I need this I wouldn't of bough this product. Its almost an scam.

Value for money 💰

Great value for money 😋

over all pretty great

at first I hated the flavour but now I don't notice it it does its job well and I have made a lot of progress because of it I think its a great product that if your struggling to get enough weight in then its a good idea go get this I haven't got any other than chocolate before so don't know what the others taste like but the chocolate is alright don't leave it in a bottle for a long time like a day or 2 as that will cause it to smell really bad and be rurally hard to get rid off but still is possible top with a good hand wash

Recommend for protein shakes

This one is the best that i used!

You get what you pay for

Thought I’d try this as it seemed good value based on the £/per g of protein. I usually get a 2.5kg pack of protein which tends to last me several weeks. However, the mix here is quite low in concentration at only 29g of protein per 100g of powder.

That equates to a bizarre recommended dose of “3 & 1/3” scoops for a single 500ml shake, per the instructions (although I find two heaped scoops equates to roughly 100g using my scales).

The mixture itself is also quite underwhelming. Despite the huge amount of powder required, the shake is still was quite watery even using whole milk. A fine “grit” residue also remains which you can feel between your teeth (even after mixing thoroughly in a shaker bottle with a grid). The taste isn't offensive but I wouldn't say it is especially rich, just like a very thin milkshake.

Overall it's probably fine for beginners and if you’re just looking to bulk but next time I think I’ll spend the extra £5-10 to get something better quality at a higher concentration.
