If you are serious about building lean, strong muscle, Sci-MX flagship protein product is a must! Sci-Mx GRS-5 Protein System is a new generation, scientifically formulated protein drink designed to supply a sustained release of proteins for longer periods that ordinary protein.
When subjected to weight or conditioning training, muscles grow in size and strength more effectively if constantly supplied with amino acids over a gradual period. Immediately after exercise, muscles require rapidly metabolised proteins like whey protein isolate and concentrate.
Sci-Mx GRS-5 Protein System contains optimum quantities of both. For the periods in between training sessions, meal times and during sleep, muscles continue to repair themselves, and this is when gradually absorbed proteins are best.
So in addition to whey protein, Sci-Mx GRS-5 Protein System also contains gradually released proteins from milk, egg white and soy which together with work in synergy with a complex enzyme package called OptiZyme, which increases the uptake of BCAA’s (branch chained amino acids) and free form amino acids.
The addition of Aminogen, a breakthrough US patented compound which has proven in clinical research to increase BCAA release by up to 250%, and boost nitrogen retention by 32%. Essential amino acids and a vitamin package designed to aid the metabolism of protein complete GRS-5 as the ultimate choice for anyone serious about muscle size and strength.
Sci-Mx GRS-5 Protein System is virtually carbohydrate free so as to promote fat loss and encourage leanness and muscle definition. It is also delicious and mixes easily with water into a creamy and satisfying shake.

Sci-Mx GRS-5 FAQ
- How does GRS-5 Protein System differ from Sci-Mx 100% Whey Protein?
- Sci-MX GRS-5 Protein System is made from a blend of 5 different types of protein, namely whey protein isolate and concentrate, egg albumen, calcium caseinate and soy protein isolate. This variation of protein sources provides a wider spectrum of amino acids than if just one or two protein sources are used. Along with the addition of Aminogen, it also ensures a slower and enhanced, sustained time-release effect as each different protein type is synthesised at a different rate by the body. Ideal for in between meals or at bedtime to ensure long periods of amino-acid supply
- Sci-MX 100% Whey Protein on the other hand, contains a blend of whey protein isolate and concentrate only. This product offers the highest BV (Biological Value) protein source available, rich in branched chain amino acids (BCAA’s) and very quickly synthesised and made available to recovering muscles. Ideal as a post-workout protein source

I strongly recommend this product for the fact that it has both fast releasing and slow releasing amino acids which keeps your body from scavenging itself for protein.

Very good, tastes not bad
Fills the gaps
Review posted on 26 May 2011
As a competitive athlete, I can't rely on food alone to keep me lean and keep up with the demands of my body's need for Protein. GRS-5 from Sci-Mx has a mixture of both slowly absorbent and fast absorbing amino acids. This means my body is constantly getting nutrition. GRS 5 has helped me lose 3 stone from an athletic 100 kg body weight down to a super lean 79Kg while maintaining my 100kg strength totals. I highly recommend it. Wish one could get a price deal on it though as I go through the stuff quickly and it isn't long before I have to charge my account again.

All the ingredients are here for good reason, with no unnecessary stuff chucked in. Aminogen is the trump card here bringing this protein to the next level. After this shake I feel satisfied for long time and my muscles feel pumped during workouts.
Good all rounder

The best-tasting protein shake I've ever tried. Mixes like a dream and quality ingredients. The rapidly-absorbed sources complement the slower release sources making it perfect for my muscle building endeavours.
Best so far

digestion friendly
Review posted on 29 Sep 2010
I have tried many proteins and this is the only one that does not give me digestion problems or leaves me feeling bloated.
Plus the results i'm seeing are far better than any others i have had. I would thoroughly recommend this to any one having problems with other proteins.
