About Maximuscle Whey Protein Isolate 2.5KG

Whey Protein Isolate is created using cross flow membrane filtration with the resulting protein being spray dried to form isolate whey protein powder with fast release protein for quick amino acid delivery. With a protein concentration between 88- 96% (depending on the flavour) and a lower fat and sugar (lactose) content versus whey protein concentrate powders, whey protein isolate powder is ideal for all serious trainers who desire support lean muscle growth and development. WPIis an ideal protein to use after training, between meals or to have stacked with other Maximuscle raw ingredients.

The benefits of Whey Protein Isolate

For an individual looking for muscle maintenance, growth and development - protein is the key. Having a positive protein balance stimulates muscle protein synthesis, which when combined with resistance exercise, results in muscle hypertrophy. Found within whey protein isolate are the naturally contained branched chain amino acids (BCAA’s): Leucine, Isoleucine and Valine, all of which cannot be synthesised within the body and need to be provided from the diet. Whey protein isolate has a faster digestion time to whey protein concentrate with less carbohydrate and fat, making it a hit with exercises who want to take the extra step.

Stuart Allen Fantastic protein powder!
I have been using sport supplements for the last Seven years and have always preferred Maxinutrition for a number of reasons (Mainly that I trust GSK and the research they have put behind the products as well as the work that goes into their Human Performance lab for their athletes). This is the first product I have used that I have been so impressed by that I have been moved to leave a review. This protein poweder is by far the best I have ever tried. Mixability: The powder is incredibly fine and mixes with water without the need for a mixing grill or shaker ball. I am fairly sure even a quick whisk with a fork would do the job. The consistency is smooth with the recommended 200ml of water. 10/10. Flavour: This is all about preference and I am sure your taste buds will not be the same as mine, so this can I guess be taken with a pink of salt. For me this is the best tasting protein powder I have ever tried. It does not taste powdery at all and the flavour I chose (Raspberry) tastes exactly the same as angel delight. I absolutely love angel delight, so this has made me an incredibly happy camper! This is also very low in carbohydrate and therefore is something I can fit into a Ketosis diet without any qualms unlike some other brands/products. I would give this product a huge thumbs up and recommend to anyone looking for a new protein powder to try.
