Firstly, I am severely lactose intolerant and this means I'm limited to what protein I can have, so I thought that I'd be stuck with really gross options. I've tried so many, and was suffering (in silence) about how disgusting they were. Then I found MyProtein after some searching and took a risk by trying the Smooth Chocolate and Strawberry Cream. O M G! I have double scoops for meal replacement and protein loading for circuits, dancing, PiYo, ChaLean Extreme, P90X and weight management. Two scoops is the important bit for me because most protein doesn't mix well, even with a blender. I load my shaker, then with very low expectancies give it a thoroughly good mixing testing with the Chocolate first...it mixed, and no blender! Next came the taste...it was good! And I mean, really good, definite chocolate tastes, nutty aroma, went down really easily sipping it, no nasty after-taste either! The next day, I had a chocolate one in the blender, fantastic. Really smooth and creamy, take care with the amount of milk (I use Lactofree blue), not enough and it's not nice, but get your amount right, memorise it and keep to it. I eat a main meal at lunchtime, then in the evening I tried out the Strawberry Cream, used a shaker, mixed two scoops and O M G! It's even nicer than the Chocolate Smooth!!! How is this possible? Now, I mix one scoop of Strawberry with one Scoop of Chocolate for ultimate NOMZ!! The protein content is high, not as high as the unflavoured but I don't want to have to add fruit to make it taste nice, it would defeat the object of low carb and high protein. For anyone with a need to have Soya protein, this is the nicest I have ever tasted and I've already ordered my second set! Mix with shakers or blenders, add in fruit, I'd say blueberries, put in in cake mix for protein sponges, Lactofree milk, Soya milk, and Almond milk.

Bought this for it's higher protein content. Found mixing the powder with a small amount of liquid first and letting it settle slighty before adding the rest of the liquid worked well. Combining it all together at once resulted in some horrendous lumpy and ridiculously frothy mess. I add coffee to mine, which helps make it more palatable.

I normally have whey protein but recently discovered I have a milk allergy so tried this. The best way to describe this is angel delight... it is so thick it doesn't come out my shaker. It should be sold as a dessert mousse. Make sure you take a spoon with you to the gym.

A bowl and spoon.

I've used this product for several years now and am highly satisfied. It is easy to digest and a truly excellent source of protein in my diet - which as an 80 year-old vegetarian - is of great importance to me! It is always delivered quickly and in good packaging.

First off, I am not actually milk, lactose or whey intolerant. I take this excellent protein supplement simply because of its amazing value and complete amino acid profile. It is significantly cheaper than the whey product alternative which very important to me as I am on a very restricted budget. It is also easy on the digestion with absolutely no side effects whatsover and is really helping my gains - it's even improving my beard growth! Additionally, I had been using a competitors Soy Protein Isolate as it was slightly cheaper but after I received a discount code from MyProtein, I decided to try their product. In short, it is far superior in both taste and mixability being much smoother in consistency when mixed with no lumps and less frothing. Sure, you've got to get jiggy with the shaker when mixing but hey, if you can do the weights or other exercise then shaking it up shouldn't be a problem. I will now only use the MyProtein product which, even without flavouring, tastes just fine to me but then I ain't a fussy Mummy's boy.

Flavour: Unflavoured. I can generally stomach a lot, but this stuff is just the worst. The texture is so bad, it's thick like cement and gloopy. I actually turned my shaker upside down and it took about 10s to drip out. I added double the water and it was almost just as bad. Unfortunately I was not allowed to get a refund. I wish MyProtein put a warning on the product that it's basically cement.

Struggled with a dairy allergy/intolerance for years. Find the higher grade protein brands and those that claim to be lactose better for my stomach and breathing problems, but always affect me. Thought I'd give this a try, wasn't sure what to expect. Tastes great, mixes well. Only downside I've found is its a little foamy and takes quite a while to settle down. Would like to see the product available in a larger quantity as well.

Nice alternative to whey and casein

Soy protein makes a great alternative as a vegetarian protein compared with whey and casein based protein powders, this protein powder tastes nice in vanilla or chocolate and still provides all of the essential amino acids to support muscle development. I find this mixes easily in around 350ml of water or soy milk, I am not vegetarian or vegan and like to mix up my proteins from month to month. This does combine great with micellar casein and impact whey for a complete varied protein muscle building shake. To get a great discount on your order use code geoff - rdt (with no spaces in between) in capital letters, thanks again and hope this was of benefit to you :).

I have bought about three batches of unflavoured spaced about 4 months in between, and I would say that the mixability went from medium-to poor-to good. I was told by the sales guy that it depends on the source of the protein. I had to use a blender to mix the powder in. Anyway the soya taste does not bother me. For effectiveness, I would say my gains were better than when I used whey -- apparently I am lactose intolerant.

I bought these products the other day as I have trouble with milk. I bought 1kg of Strawberry and 1kg choc smooth. The chocolate is ok, I have it mixed with 400ml water as it was way too thick with the recommended ammount, and I also blend in a banana to help with the taste. It tastes find when blended. The strawberry has been not so great to me. When you mix in a shaker it goes to half foam, half drink... I'm not sure why, and it makes is hard to drink, and the texture and flavour is not great. I think I'll stick to the chocolate when I've run out this time. Its good for the money and for the dietary requirements I have.

Goes Well With:

Rice milk, Water with banana.

I am a vegetarian so I bought this too add more protein to my diet. It definitely has helped in my training for a marathon but does come out very thick and lumpy. Better when you add more water then recommended. I went for unflavoured to add to different smoothies, so I could have a variety and because protein level is different in flavoured varieties. Can't complain too much as the price is very good.

Goes Well With:

In smoothies usually either 1 scoop plus a handful of frozen berries and a banana or 1 scoop plus a tbs peanut butter and a banana. You can taste the powder less in the peanut butter version but I like the variety.

I have turned to a non diary protein due to the whey protein giving me spots which I expected, as I get this with all diary products, although I still can have it once a week. I ordered the vanilla flavour soy protein as the chocolate whey protein is a bit sickly for me. I made it as usual and did find it mixed a lot thicker than the whey protein & therefore had to add a lot more almond milk & a bit of water. I find the vanilla taste of this is delicious and once you add more liquid the texture it just a notch down in comparison to the whey mix. Nice recipe to make is 1 scoop powder, 300ml Almond milk, handful of frozen blueberries, ice & blend. Tastes like a blueberry muffin - great for breakfast! :) Overall a decent non dairy alternative.

Goes Well With:

Almond milk & a blender

Used as a meal replacement, one for breakfast and one for lunch in fruit smoothies blitzed in a blender. Prefer the chocolate smmoth flavour to the original flavour, also sometimes add some cocoa nibs or cocoa powder (5g per 30 of powder) for extra chocolate taste!

Goes Well With:

Frozen fruit, juices and coconut/almond milk. Have used a various combinations of raspberries, blueberries, cherries, mango, kiwi, pineapple juice, and orange juice. Also cocoa powder or cocoa nibs.

Pleasantly surprised

I decided to buy this as Whey protein results in acne for me and I have to say, I'm pleasantly surprised. The Strawberry Cream tastes great, I find the Vanilla has a slightly bitter aftertaste as a shake, but works well mixed in porridge or a pancake batter. The down sides? It doesn't mix as well as the Whey powders, but pop it in a shaker and it's fine and I would say add more liquid as it has a much thicker consistency. As for gains, it's too early to give a review but I will definitely be purchasing this product again.

Great as always! I always buy this protein powder, I love it and take it 3 times a day plus! I have it with oats for breakfast, with milk as a mid morning shake, before a workout I take it with powdered oats and milk with coffee as a flavouring and after a workout something similar, it's really good and I highly recommend it!

Goes Well With:

Milk, porridge, oat powder and as a protein bar mix!

This soy protein is not too bad in the chocolate or vanilla flavour options, they are much nicer than using it unflavoured, i like to mix up proteins sources from time to time and this works well as a sub for whey and casein or used in addition to provide different amino acid ratios, i feel to overcome sticking points in progression in adding muscle mass it is important to mix up diet as well as training, i like the fact that this mixes to form quite thick and dense shakes which makes them more filling when used during fat loss / cutting phases. if you found any value in this review then please use code: GEOFF - RDT (no space in between dash and letters) and all in capital letters at checkout to get up to 85% off order depending on current offers, thanks and i hope this was of benefit to you :).
