    Here’s your essential amino acid supplement, containing an optimal 4:1:1 ratio of leucine, isoleucine, and valine.

    These can’t be produced by your body so they must come from your diet, and that’s where we come in.

    What are the benefits of BCAA 4:1:1?

    It contains three popular essential amino acids – the building blocks of protein that make up the structure of new muscle tissue. This is so important for any fitness goal, whatever your aim.

    Plus, this 4:1:1 blend offers you added leucine for those hoping to reap the benefits of this specific essential amino acid – proving a popular choice throughout the fitness community.

    When should you take BCAA 4:1:1?

    We recommend taking 5g 2-4 times a day for best results – enjoying one of our fruity flavours, or simply adding to your favourite shake.

    These amino acids can be taken throughout the day, or before, during and after exercise.

    For even better results, try it with…

    Creatine Monohydrate – it’s proven to increase physical performance in successive bursts of short-term, high-intensity exercise –ideal for improving strength and power.*

    *The beneficial effect is obtained with a daily intake of 3g of creatine.​

Good purchase

Happy with this purchase. A lot of the reviews talked about it having a terrible taste. I got the Tropical one and don't have any problems with it - tastes like squash. Slightly frustrating that it doesn't come with a scoop despite the instructions saying "two scoops" rather than an amount - so very hard to know how much to use. Have noticed a difference in my muscles not being as sore after workouts.

Good stuff

Great taste and essential to a intense training programme. Well recommended.

Goes Well With:

Water cold or warm

Quality product

Pop them down 2-4 times a day as instructed and seeing a big improvement in muscle mass and performance at the gym

Goes Well With:

Green tea extract


This stuff is great! Having read other reviews I was bracing myself for it to taste terrible but the Tropical flavour is more or less just like a tropical squash, there's a definite 'something' about it that let's you know it's not but its perfectly palatable. In terms of effectiveness I couldn't be more pleased. I've dropped a total of 15 kilos in weight in the last couple of months with pretty much no muscle loss to speak of. Obviously it's impossible to be sure but I'm sure the BCAAs have helped me maintain my muscle mass.

Good, now too expensive

Was buying this item every 2 weeks but the price has pretty much doubled this month. Love the product but now too expensive

Poor taste

Bought the Berry Blast flavour as had tried another previously and was awful. Love all the other MYPROTEIN products but this really is a complete let down. Won't be buying again. Will be using an alternative product.

BCAA 4:1:1

Great taste, great value for the money, highly recommended.

BCCA Tropical

Absolutely amazing! Love the taste, finally not sickelishly sweet and a little bit sour too, which I like very much, very refreshing and light taste. Of course it mixes well, no troubles with that. Recommend! I bought previously Lemon and lime, my first BCCA powder, it was all right, but very sweet. I wish MYPROTEIN wouldnt use sucralose in every product. Its just too sweet

Berry blast disappointment

Normally buy raspberry lemonade and tastes fantastic but thought I'd try something different and got berry blast, well I won't buy it again there is no flavour to it at all. Highly disappointed.


I have mainly taken protein powder but have been suffering from muscle soreness and tiredness as now having to cycle 8 miles a day, I was struggling to get my training in as a result this product seems to be having a positive effect and has made a difference I would definitely recommend this to anyone, it doesn't taste the best but is easily drinkible

Goes Well With:

Water before training
