This soy protein sample is a great way to check out other protein sources available to you. I was pleasantly surprised with how good this protein was, it doesn’t mix to a watery smooth texture but instead has more of a frothy texture which in my opinion was actually quite pleasing.
The protein content is superb and with this product being vegan it means there is near no chance of any reactions occurring from it.

My wife regularly uses this as she is able to add bananas to help give it some flavour. It always work well and is her to ‘go to’ if the flavours available are not to her taste. Without doubt her favourites are the salted caramel and chocolate salted caramel but if they are not available this is a very good substitute. It does what it says on the tin!
Goes Well With:
Soya milk, oat milk, almond milk, coconut milk, but add fruit to help give it some flavour

Bought the sample to try out for the first time. I don’t drink protein shakes so I added half into baked oats and half into oat pancakes and they both turned out great. I will definitely repurchase

THE best protein I have ever had. I’ve tried near enough every flavour and this Salted Caramel knocks them all out of the park. It’s not only a taste sensation but it never reacts like other proteins do when you add heat. It mixes into porridge like a dream. I’ve been waiting on the salted caramel flavour coming back in stock in the 2.5kg bags… I’m too obsessed🤩🫶🏽

A perfect salted caramel flavour that isn’t just over sweet and is dairy free!
Goes Well With:
Oats, weetabix, yogurt

I started on soya protein a decade ago – never had whey so I can’t compare the two!
Back in’t day, we only had chocolate and vanilla to choose from, and they were a chore to chug down.
Having a huge range of flavours now is brilliant. I find the soya protein mixes much better and is far smoother than the other Vegan protein blends, and being able to try samples is really helpful when you don’t want to commit to something that might taste awful.
The popcorn flavour is interesting; not quite popcorn but still nice to drink! The speculoos is awesome and is just like a biscoff milkshake!
They are definitely on the sweet side, though!
Goes Well With:
Almond milk, water

This soy protein is really really good. It mixes pretty well, and I love how thick it is. The flavours are really good as well – salted caramel is extremely tasty. Only downside is that the powder has a woody smell to it that you can slightly taste, but nothing major.

Got the sample as the reviews on this are quite mixed and hoooly cow was I surprised.
Yeah, the texture isn’t as smooth as whey, which can be a turn off. I got the salted caramel (which I’m sad to see isn’t an option on bigger sizes, hopefully in future?) and it was strong and very very tasty.
I mix mine into fruit smoothies, and with bananas and blueberries I found the texture is comparable to the standard vegan powder, and the flavour way stronger than the whey. For me it’s worth putting up with some bit of graininess for the taste, but might feel worse mixed with just water.

This one is absolutely delicious. Honestly was like cake, totally amazing, properly loved it. Even where I’d not mixed it properly from rushing-that didn’t put me off I was still in there, tongue was like a rat up a drain pipe. Hmmm Hmmm hmmmm
