USN BCAA Power Punch review


USN BCAA Power Punch is available in 36 servings. At the time of writing, our best offer is £18.95. If we break this down by size (400g), this works out at £4.74 per 100g of powder. This is just above average for a BCAA powder. During this review, we will identify whether this an above average BCAA product, or if it’s a great product with a decent price tag.



Taste is important when it comes BCAAs, as you drink them during your workout, so you need to have a flavour that you like and enjoy. USN BCAA Power Punch is available in 3 flavours. We won’t list them all, however, we did try two flavours, and we will discuss them below.

Firstly, we tried the Blue Raspberry. This is a good flavour but it’s a lot sweeter than other blue raspberry flavours we have tried, and it’s a much fuller, tangier flavour of raspberry.

Secondly, we tried the Tangerine flavour. This is a very tasty flavour and very refreshing. It’s got that zesty, wholesome flavour, and tastes like a very strong, posh cordial. It can be a big too twangy after a while, especially during a workout, however if you love the idea of a citric, strong, fruity drink, then this is for you.

Overall, we are very happy with the taste and flavours of the two we tried. The final flavour we did not taste is Watermelon, but we can say with confidence that this would taste great if we go by the ones we tried.



BCAA powder can have a very dusty, light yet thick texture. It’s very rare that you will find a BCAA powder that does not mix well, as long as you follow the directions from the manufacturer.

We mixed a serving (roughly 13g) in 1l of water. After all, it is a drink that you should use during your workout, we wouldn’t recommend using it before or after. We would not recommend using any other liquid. It mixes really well and we had no issues with less liquid or more powder, and it’s mixability.

Remember, the amount of liquid will change the taste – less liquid will mean it is slightly thicker with a stronger flavour, but more liquid will mean it is slightly thinner with a weaker flavour.

As BCAAs are intra-workout (during your workout), you should drink this slowly whilst working out. We found that 1-1.5l lasts around an hour and a half, obviously depending on how much you drink.



This is where it gets interesting. At their core, BCAAs will contain amino acids, but they main contain other ingredients and compounds that boost your energy a little more. BCAAs are considered essential because, unlike non-essential amino acids, your body cannot make them. Therefore, it is essential to get them from your diet. Contrary to most other amino acids, BCAAs are mostly broken down in the muscle, rather than in the liver. Because of this, they are thought to play a role in energy production during exercise. More importantly, your body can use them as building blocks for protein and muscle.

First off, we’ll explore the nutritional information. In terms of BCAAs, we have a 2:1:1 ratio (3.5g Leucine, 1.75g Isoleucine and 1.75g Valine). This totals 7g per serving, which is ok. If you compare this to MyProtein’s Essential BCAA 2:1:1, it does have a lower dosage of BCAAs. But, this is due to them being diluted by additional nutrients, aminos and ingredients. USN BCAA Power Punch also contains 500mg of Citrulline Malate and 2.5g of Glutamine, that produces nitric oxide, improving the pump and oxygen in the blood, as well as fat-burning and muscle fuel respectively.

Secondly, we’ll discuss additional ingredients. It does contain artificial flavours, colours and sweeteners, however 99% of the products we have reviewed do contain these. It also contains BioPerine, which helps the absorption of nutrients in the blood and improving the metabolism.

Finally, the macronutrients. Per serving, we are getting 34 calories, 0.3g of carbs, no fat and 8.3g of protein. This protein will also hep with repairing and fuelling your muscles during your workout.

This is a good amino powder, as it provides the BCAAs and two other essential amino acids required for muscle building, fat loss and energy production.
