Reflex Nutrition Growth Matrix

Growth Matrix is the only post workout drink to exclusively use very high DH whey protein hydrolysate as its sole source of protein

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.

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 synthesis
Growth Matrix contains a massive 7,000mg of free form L-Leucine per serving. L-Leucine is known for its ability to initiate biological signalling via mTOR (mammalian target of rapamycin) - in simple terms it may trigger increased protein synthesis when combined with hydrolysate protein and carbohydrate taken after resistance exercise.

Recover sooner with peptide bonded glutamine & Creapure® creatine
Each serving of Growth Matrix contains 5,000mg peptide bonded glutamine and 2,500mg Creapure® creatine monohydrate. Two important ingredients for replenishing glutamine and creatine phosphate levels after an intense workout or exercise.

Essential electrolytes and glucose polymers
Intense training leads to a loss of essential electrolytes and a reduction in muscle glycogen stores. Each serving of Growth Matrix provides over 50g of fast acting glucose polymers and added electrolytes to restore the balance as quickly as possible.

Uncompromising formulation
Growth Matrix has been formulated without compromise, offering potent muscle building ingredients at high doses. High quantities of hydrolysed proteins and amino acids make for a strong, quite bitter taste. Available in 3 flavours (orange & lemon, rich chocolate and smooth fruit).

"I have tried many post work out but this the one I stick to - really good.
I know the others are not that great tasting but the chocolate is good"

"Foul foul taste! Just pour it down your throat and swill with water.
Great results. Shame about the taste.
Will buy again."

"Ok so everyone is right, this tastes foul. After a couple of days though I was used to the flavour. The effects were excellent. Definately the best post workout I've tried. Persevere through the taste and enjoy the gains"

"Excellent product, I am on my second tub now. Increases recovery time, replenishes the muscles with sought after nutrients eg. Creatine, hydrolysed protein, glutamine, glucose polymers, carbs and more.
You could have hard session at the gym, drink this bad boy, and the next morning have no muscle aches what soever , and see the definition in you muscles.
The only negative point is that the taste is rather unpleasant, but I do not drink it for the taste, I drink it for the results, and that is what I get."

"amazing product, if you can deal with the appalling taste you will notice the huge benefits. the first time i took this i trained chest with a lot of sets took growth matrix and the next day when i expected to be sore it felt like i could train it again, i hope you have the same results!"
