Reflex Nutrition Growth Matrix — Advanced Post‑Workout Recovery Shake

You’ve put in the work. Now lock in the results. Reflex Nutrition Growth Matrix is a performance‑first post‑workout shake engineered to take full advantage of the training window—when your muscles are most primed to rebuild. Powered by high‑degree hydrolysed whey, it delivers a rush of fast‑absorbing di‑ and tri‑peptides that get to tired muscles quickly, helping you bounce back stronger.

Each serving combines 38 g of premium protein with a powerful 7 g of free‑form L‑Leucine to kick‑start muscle protein synthesis. You also get 53 g of fast‑acting carbohydrates to replenish glycogen, 3 g of Creapure creatine to support high‑intensity performance, and vitamin B6 to contribute to normal energy‑yielding metabolism and the reduction of tiredness and fatigue. The result? A serious recovery formula that helps you feel ready for the next session—sooner.

Why you’ll feel the difference

Ultra‑fast protein delivery: Hydrolysed whey peptides absorb quickly, feeding muscles right after you rack the last rep.
Leucine-loaded signal to grow: 7 g free‑form L‑Leucine teams up with 38 g protein to switch on muscle protein synthesis.
Smart carb refuel: 53 g rapid carbs help restore depleted glycogen post‑training, supporting your recovery between sessions.
Proven performance support: 3 g Creapure creatine increases performance in successive bursts of short‑term, high‑intensity exercise.
Feel fresher, train better: Vitamin B6 contributes to normal energy‑yielding metabolism and helps reduce tiredness and fatigue.

Who it’s for

Strength and physique athletes focused on building muscle and accelerating recovery.
Field and court players who need to rebound fast for repeated sprints and powerful efforts.
Endurance athletes looking for rapid protein and carbohydrate replacement after long, demanding sessions.

How to use for best results

Have Growth Matrix immediately after training to maximise the post‑workout window. It mixes smoothly with water and is designed for convenient, consistent recovery—session after session.

Smooth Fruit??? NO

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 My GYm Supplements if I can send it back.

YUK!

Best post-workout product

As always, the people at Reflex have put together a great product. This one is designed to ONLY be used post-workout. Best to see the info at Reflex for everything that is included in this product.

The only sssues with the product are:

(1) the fact that the taste takes a bit getting used to

(2) the cost

However:

(1) after a few weeks of using the product, I do look forward to it. See my mixing advice below.

(2) but considering the ingredients list...this product is actually fairly cost effective; to stretch it out a bit more... I sometimes only use 70 grams of product instead of the full 105 (and then supplement with some whey)

Best way to mix?:

Despite some reviews to the contrary, I find Reflex mixes perfectly...but I advise buying the Reflex shaker...as other products just don't compare. Before the workout, I put 400-500 ml of water into the shaker...add 2 scoops of product and some whey.. (or 3 scoops of product)... add a scoop of powdered milk... shake until dead smooth. I then put in about 5 ice cubes and put in the fridge. At the end of my workout... the ice cold chocolate shake is there to enjoy.

I've found fruit only makes this product taste worse...milk or water in my opinion is best. Also best ice cold.

This product (like all Reflex prodcuts in my opinion) does not cause me any stomach or gastric upset; and only makes me feel good.

Five Stars

The product is awesome but the flavour not as per my request and bad taste.

The ultimate post workout supplement for anyone!

I have tried at least 30 different protein shakes over the past 8 years and nothing beats this...Since using this product for the last 3 years it has become the only post workout protein supplement that I will use or recommend to anyone else. The chocolate flavour is my favourite and the taste is not amazing but that should never be the point when buying a high quality post workout shake that has the best ingredients profile you can find! Reflex is definitely one of the best supplement companies in the world and you can always trust their products to give you the results that you are looking for. I find that the serving suggestion is a little bit too much for me and by cutting it down to 2 scoops it mixes better and lasts a bit longer while still helping you recover much faster than normal. I really hope that they never change this product or even worse stop manufacturing it.

Tastes Horrible and Makes you feel sick to drink

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???)

Quality Product

Taste seems to be the main criteria for rating whey based supplements, but to the serious trainer it should mean nothing. This is a high quality product and delivers - no, the taste isn't great, but you get used to it!

Number 1 post workout

Expensive for what it is but the best post workout on the market IMO. I've been using this on and off for prob 10 years and nothing compares.

Tip: Don't get the orange one it's disgusting but the choc one tastes great.

Disgusting. Really bad taste. Will never buy again

I've had a lot of protein powders and most taste quite similar, quite bland and that's fine. This one tastes really really bad. It's sharp and nasty and a struggle to drink. Exceptional and shocking. Will never buy again

Great stuff - taste isn't great.

Taste is a bit manky, but you get used to it.

The fact that this product is hydrolysed is the reason for the taste, gives the body less work. Immediate consumption of protein and carbs is fantastic immediately after a work out.

If only people understood the difference between- Concentrate/Isolate and Hydrolysed!
