## Description

"the world's best post workout recovery! a very bold statement, but a statement never the less that's' backed up by fact. Growth matrix is like no other.it's the only post workout drink to exclusively use very high dh whey protein hydrolysate as its sole source of protein. It's the highest quality whey protein that's been extensively treated with enzymes to provide a potent array of di & tri peptides for immediate absorption leading to an almost immediate increase in protein synthesis. This is coupled with an almost impossibly high 7,000mgs of l-leucine to boost protein synthesis even further; results when combined with the included glucose polymer matrix verge on pharmaceutical. There is a downside though.when science comes first flavour often comes as an afterthought, and since growth matrix is at the pinnacle of sports science i'm the first to admit that it really does not taste that great. However if you can stoach the taste i'm sure you'll agree the results are absolutely worth the off taste."james phillips m.d reflex nutrition.fully optimised post workout protein absorption and synthesisfaster protein absorption and improved utilisation from hydrolysed whey protein, l-leucine and vitamin b6.hydrolysed whey protein is whey protein that has been treated with enzymes to break the protein down into smaller peptides and amino acids. The benefit is that your body can absorb peptides much faster than whole proteins. This leads to almost immediate absorption of nitrogen. Included in growth matrix is vitamin b6 which is involved in protein and amino acid metabolism. Vitamin b6 helps the body to more effectively utilise the high doses of protein and amino acids found in growth matrix.increased protein synthesisgrowth matrix contains a massive 7,000mg of free form l-leucine per serving.

Review: Five Stars - The product is awesome but the flavour not as per my request and bad taste.
Review: DO NOT GET THIS!!! The product tastes absolutely disgusting and is inedible, I have had a lot of different protein shakes over the years and know what should be right and what is not. This is hard to keep down and makes you feel sick, go elsewhere and save your money as they don't offer refunds (Hmmmm I wonder why that is???)

I tried this for the first time today, and I have to agree with other reviews, Smooth Fruit flavour is vile! I'm going to check with Amazon if I can send it back. YUK!
