MuscleTech Amino Build Next Gen review


MuscleTech Amino Build Next Gen branched-chain amino acids powder is available in 30 servings. At the time of writing, our best offer is £18.95. If we break this down by size (275g), this works out at £6.89 per 100g of powder. This is quite expensive and, for example, is more expensive than EVLUTION Nutrition’s BCAA ENERGY. During this review, we will aim to identify whether this is one of the better products on the market, or if you are just being overcharged.



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. MuscleTech Amino Build Next Gen is available in 4 flavours. We will not write the full list, however we will discuss the two flavours we tried.

Firstly, we tried the Icy Rocket Freeze flavour. A strange flavour indeed, however it tastes like those rocket lollies you used to get from the ice cream man back in the day. It’s a very fruity flavour, quite tropical, and is very sweet. We would recommend diluting this a little more than directed by the manufacturer, but if you have a sweet tooth, then it could be perfect for you.

Secondly, we tried the Watermelon flavour. This was a good flavour but, unless you love watermelon, we’d probably avoid it. We can’t help but think that watermelon flavoured products are better suited to pre-workouts. It’s a very wholesome flavour and could be quite hard to sip during a workout.

Overall, we are happy with the flavours. We’re not sure on the white raspberry, though. That could be an odd one.



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 1 serving (9g) in 1l of water. After all, it is a drink that you should use during your workout, we wouldn’t recommend using before or after. We would not recommend using any other liquid. It mixed well but was heavily diluted, so you could definitely squeeze one or two scoops in there.

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. Per serving, we are getting a 2:1:1 BCAA ratio of Leucine (2g), Isoleucine (1g) and Valine (1g). This is 4g per serving. This is ok, but not great, there are other powders with more included. But, the less BCAAs is made up for in other compounds, such as 500mg Citrulline Malate for extra energy, 500mg of Glutamine (used as muscle fuel), 500mg of Taurine (water retention in muscles, important for getting a pump) and 500mg of Alanine (providing energy for muscle tissue and the central nervous system) and 500mg of Beta-Alanine (increasing exercise capacity). So, we have the BCAAs, as well as other compounds that provide energy during your workout. It depends on whether you want this powder solely to provide BCAAs, or a mixture of BCAAs with additional energy. If it’s the latter, this product could pair up with a pre-workout for even more energy.

Secondly, we’ll look at the ingredients, which include a mixture of natural and artificial flavours, artificial colours and sweetener (sucralose). It also includes malic acid, for boosting sports performance and increasing the absorption capability of creatine, and anti-caking agent, which is linked to long-term health issues, but only if over-consumed in large doses. This is used in the packaging of the product, and it is unlikely that there is a high enough dosage to cause any problems.

We definitely noticed an increase of endurance whilst using this powder, as well as a slight increase in explosive power and alertness. BCAAs are taken for the long-term results of muscle retention and building. It would be fair to say that this could play the role of a pre-workout – it wouldn’t provide the same amount of energy, but it would provide some, and save you money. Remember, during a workout, you are consistently breaking down muscle tissues that need feeding with amino acids and protein to remain strong and keep building.
