Echo Supplements on Grenade Hydra 6
Grenade Hydra 6 has been formulated to be the only protein shake you need to buy for all times of the day including first thing in the morning and before bed. To achieve this Grenade have paired up the fastest releasing protein source: whey protein isolate, and the slowest: micellar casein. The end result of this is that when you have a serving of Hydra 6 you get an almost instant hit of protein from the whey protein isolate and this is sustained for over 6 hours due to the micellar casein content.

Whey protein isolate has been chosen as the fast releasing component of Hydra 6 because it is extremely low in carbohydrate and fats which makes it very easy to digest when compared to lower grade whey concentrates, and also very rich in branched chain amino acids (BCAAs) and glutamine. Whilst whey protein isolate is not a cheap ingredient it is the most effective and this is why is has been included in the Hydra 6 formula.

When it comes to slower releasing protein sources Micellar Casein is the undisputed best choice; there are other options which may be cheaper to include, or taste nicer but when designing a product for it's effects you really want the best and Grenade have provided that with micellar casein. The effect of the slow releasing part of Hydra 6 is to prevent muscle breakdown (catabolism) - micellar casein is strongly anti-catabolic and it's effects last at least 6 hours.

While this is great, the most important effect of Hydra 6 is that the effects of this 50:50 blend are actually more than the sum of their parts. It has been proven that as well as having an anti-catabolic effect, a whey protein and casein blend also has a stronger anabolic (muscle building) effect than whey protein on it's own! This makes Hydra 6 a really intelligent choice of protein shake as well as being more convenient with only having to buy a single protein product for all times of the day. Hydra 6 is available in 4 flavours and 2 sized tubs - this product is the larger 1816g tub which provides 51 servings in a tub.

Grenade Hydra 6 - Manufacturer's Description
Hydra 6 has been formulated with the ultimate form of whey protein - Whey Protein Isolate - and the ultimate form of casein - Ultrafiltered Micellar Casein - in the perfect “50/50” ratio, which research suggests to be superior to taking either whey protein or casein on their own. Hydra 6 offers the versatility and convenience of not having to buy two separate proteins for different times of the day and is designed to feed your muscles with the highest quality protein available.

Hard training individuals need “fast acting” whey protein isolate in the morning and pre/post workout and “slow release” casein protein before bedtime and at other times when protein won’t be consumed for several hours.

Declare War
When it comes to whey protein, it’s simple, science tells us very clearly that the higher the peak in our blood essential amino acid levels, the greater the signal to the muscles to start the process of protein synthesis (muscle building). And no protein can crank up essential amino acid levels to a higher peak than whey protein isolate. But whey protein may not be enough on its own. Several studies suggest that whey stops delivering amino acids after about 3 1/2 hours, whereas the other major milk protein, casein, not only delivers its amino acids for twice as long but has been shown to be superior for ensuring that muscle growth activity exceeds muscular breakdown. So casein’s ability to act like a “drip-feed” and constantly deliver amino acids to the blood over at least seven hours has been shown over and over again to be anti-catabolic (so it prevents muscle breakdown in addition to causing growth). Clearly, casein has advantages that whey protein alone cannot match.

Other studies also suggest that combination proteins which included whey and casein have a more potent muscle-building effect in the four hours after a weight-training session as compared to whey protein alone. Having established that a perfect 50/50 combination of whey protein and casein is ideal for muscle growth, the Grenade research team had one more major goal - combine the ultimate source of whey protein with the ultimate source of casein... the result is Hydra 6, one of the highest-quality protein combinations ever seen in the world of sports supplementation.

Each serving of Hydra 6 contains between 12 - 12.5 grams of protein from premium whey protein isolate (with no inferior concentrates) and 12 - 12.5 grams of protein from low-heat, ultrafiltered, native micellar casein (no inferior caseinates) for a total of 24 - 25 grams of protein per serving AND you can take it before training, after training, before bed or ANY other time you want quality protein - no more messing around having to buy two separate proteins, which are of inferior quality and actually need to be mixed to realise their full potential anyhow!

We should also mention - it tastes awesome!

Grenade Hydra 6 - FAQs
Can I take Hydra 6 alongside other Grenade supplements?

Yes. Hydra 6 can be stacked with any product from the Grenade range to help maximise results.

When can I take Hydra 6?
Due to the unique 50/50 blend of premium whey protein isolate and low-heat, ultra filtered, native micellar casein, Hydra 6 can be consumed across a number of scenarios. These include, but are not limited to: pre-workout, post-workout, bedtime and in between meals.

Why does Hydra 6 contain premium whey isolate and micellar casein?
Studies show that this combination of protein sources may have the most potent muscle-building effect compared with whey protein alone. Furthermore, hard training individuals may benefit from “fast acting” whey protein isolate in the morning and pre/ post workout and “slow release” casein protein before bedtime and at other times when protein won’t be consumed for several hours. By combining the two sources in one protein it saves you having to buy a second tub of protein.

Is Hydra 6 suitable for vegetarians?

What is the difference between whey protein concentrate and whey protein isolate?
Typically whey protein concentrates are 80% protein and whey protein isolates are 90% protein. As well as this, because of the extra micro-filtration process more fat and carbohydrates are removed. Therefore, the addition of isolates in Hydra 6 reduces the overall fat and carbohydrate content and provides a higher quality protein, which is easy to digest.

Who can benefit from Hydra 6?
Bodybuilders & strength athletes, competitive athletes, vegetarians, recreational exercisers and those new to weight/ strength training and anyone else who is looking for a simple way to get more protein in their diet.

What are the benefits of taking Hydra 6?
There are a huge range of benefits from supplementing with Hydra 6, such as: maintaining a healthy weight, controlling hunger, getting lean, boosting recovery and diminishing muscle breakdown.

I play competitive sports, can I use Grenade Hydra 6 if I am going to be drug tested?
Hydra 6 is a natural food supplement. All of its ingredients can be found in the human diet and no ingredients that are banned by any major sports organization have been included in its formula. It is impossible to say that any supplement (or most foods for that matter) is 100% free of all banned substances but no such substances have been included in its formulation.

I’m in the military, can I use Grenade Hydra 6?
Hydra 6 has been designed for athletes, fitness professionals, bodybuilders and the military, many of whom are tested for the use of banned substances. This is why no ingredients were added that contravene the rules of the International Olympic Committee, World Anti-Doping Agency, bodybuilding federations or the military. Grenade products have always been widely used by UK and US military personnel. Users consume all food supplements at their own risk, however. It is not on the Informed Sport programme.
