  • Two Premium Protein Isolate Sources - Whey Protein Isolate and Micellar Casein
  • No Amino Spiking - Full Amino Profile Declared
  • Idea for Cooking and Baking

Hydra 6 has been formulated with the ultimate for 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 Protein 50/50 Blend

WHEY PROTEIN ISOLATE is absorbed rapidly, meaning it delivers amino acids (protein) to the muscles very quickly (within 60-90 minutes). Science implies that the higher the peak in our blood essential amino acid levels, the stronger the start to the process of protein synthesis, as protein contributes to a growth in muscle mass.

MICELLAR CASEIN now plays its part. Several studies show that Whey Protein Isolate is absorbed so quickly that it is rapidly utilized and protein synthesis (muscle building) drops sharply. Micellar Casein, is absorbed at a slower, steadier rate and has been shown to be superior for ensuring that muscle growth activity exceeds muscular breakdown. Protein contributes to a growth in muscle mass.

THIS SUPERIOR COMBINATION of the 2 protein sources in Hydra 6® Studies have inferred that combination proteins which included whey and casein may have a more potent muscle-building effect in the four hours after a weight training session as compared to whey protein alone. Protein contributes to a growth in muscle mass.

With new and improved flavours, we should also mention - it tastes AWESOME!

Great tasting protein! The taste is not too sweet, just the right consistency. Mixes well with water & milk, leaves little powdery bits behind in shaker and in month, that’s why I use one banana in electric blender and top it up with milk and Grenade Hydra 6 (Killa Vanilla) works a treat! One of the best protein blends on the market, better than most major protein brands. I would highly recommend it, works well for muscle gain and workout recovery. Did I mention it tastes GREAT..!!!

Flavor - So far this is probably my second favourite flavour over a variety of protein I've tried. Can drink this with large amount of water (up to 24oz before I find it too diluted or as little as 6oz) which is a plus for me. I drink about 6 scoops a day usually and this is one of the few I have yet to get sick of. Product - With 25g of protein, 150 calories, and not much sugar (2g), along with sales that happen pretty frequently, not much to dislike about this product. This is one of the few that I recommend to people. Love it.

Switched back to Hydra 6 after another leading brand changed formulas. Taste is very subjective and personal, but this product mixes better, almost instantly with minimal liquid - mixes well with more solid foods like oatmeal and yogurt without clumps. I know I remember strawberry being available in the past - Chocolate and Vanilla are both excellent choices.

A great product that mixes easily and tastes great. There are real cookie pieces in this protein. The fact that it is a whey and casein protein is great so only one shake will do. The fact that hydra 6 is also all natural (foods that can be found in the human diet) is great aspect as well. The only drawback is for people that want a two pound size will not have it. Try it for yourself and see.

My favourite protein on the market. I like to go for a fast and slow acting protein mix. GRENADE serves us a transparent protein product containg high quality fast acting whey isolate and slow acting micellar casein. The two best protein sources of their kind. I can only recommend Hydra 6 in content, taste and texture. My number1. ADDITION: My wife is lactose intollerant. After trying a lot other Protein powders she once tried Hydra 6 is goes for it since. She does not have any bloating or any other issues drinkingit 2 - 3 times a day!

This one of the absolute best proteins I have ever had. The whey/casein mix is great, keeps you feeling satisfied longer without that bloated feeling, no GI distress whatsoever, and tastes fantastic in milk or water and mixes perfectly. The Chocolate Charge is phenomenal. The Cookie Chaos flavor could stand to be a bit stronger but it's still really good. This is going to be my new go-to protein from now on.

Great protein product for those looking for a lower calorie protein blend. Hydra-6 tastes MUCH MUCH better than the EVL Stacked Protein I used before Grenade. The 50-50 blend of casein and whey isolate is great, simple concept. I hope to try some of the other flavors soon as Vanilla was very good, but well, it's vanilla.

I actually ordered this thinking it was 100% whey and not a blend, but I'm starting to like that style of protein. Without personally lab testing every protein powder, we generally assume they all have a degree of efficacy that's relatively consistent i.e. I'm assuming the actual "quality" of protein is as good other options. What I really came here for, is the taste! After being let down badly by Cellucor and their chalky, old-milk-smelling, terrible taste this was a complete 180! I'll actually just get right to my point: MOTHER OF GOD THIS IS THE BEST TASTING PROTEIN POWDER I'VE EVER HAD!!!!!! I've been an Optimum Gold standard user for the longest time and always used it as a benchmark to gauge others, and this Hydra blew it out of the water! It blends great, but when there are still clumps, it's still somehow smooth as opposed to the dry chalky clump that breaks open and leaves dry powder in your mouth. I'm also pretty sure there are tiny bits of strawberry or something in it. Glass of Ice Cold milk, scoop and a half of this, and it's straight up like drinking a strawberry malt! As I mentioned, I don't have to resources to test the overall "quality" and efficacy of this powder, but I can say that I'm absolutely loving everything about it. So. ****. Good!
