MHP, Probolic-SR Sustained Release Bio-Efficient Protein, Chocolate, 56 Servings

I have used this product for years. I am not a professional athlete but I do spend quite a bit of time in the gym. They have recently changed this formula. It now tastes, smells, and behaves just like a casein protein powder. I know there's casein in it but it behaves like other %100 casein protein powders. If you've ever used casein protein powder you know that it's clumpy, foamy and sticky, more so than whey products. This product used to be smooth, I could just put it in my shaker bottle and go but I believe that this new formula should be blended in a blender. If I put it in my Blender Bottle (I usually mix it with 1% milk) it takes me a really really long time to shake it so that it is mixed well. Sometimes even after I shake it for a long time I open the lid to drink it and out comes dry powder. After I shake the hell out of it AGAIN and finally drink it, quite a bit of it is stuck to my teeth, the sides and lid of my Blender Bottle. I have to scrub it to get it clean as where before I could just quickly rinse it. I loved the taste of Probolic before they changed the formula and it tastes different now but it is still quite tasty and I find myself craving it. The smell reminds of cotton candy. I have used the vanilla and strawberry in the past as well but have not had any since the formula has changed. Just a note, Probolic is geared towards professional bodybuilders. I recommend reading / comparing the amino acid profile to other protein powders. I think you'll find that Probolic has a much higher content of amino acids (as much as 10 times the amount in other protein powders) than most protein powders and you may not require that much protein. I will buy this again despite the formula change and would recommend it to others.

Excellent flavor but a complete pain to mix. I've tried all different methods and really the only way to get this to mix well is either a blender and adding it slowly or stirring while you add slowly into your shaker. Other than that this product is top notch for good clean protein.

Man, I've been back in the gym for 3 weeks now. I just started taking this product 4 days ago and my last couple of workouts have been undoubtedly STRONGER. Much more energy and I feel stronger, without a doubt. I do feel like that my heart has been beating a little faster during the day, not sure if there is any correlation or not, but I think this stuff is making me feel a little jittery. I was taking two scoops per day and I'm going to scale back to one starting today.This stuff is certainly more chalky than Isopure, but it is not as tough to swallow as so many of the reviews claim. It takes about 60 seconds of stirring and there might still be a little bubble at the top of the glass, but I was pleasantly surprised at how easy this was to drink and impressed by the chocolate flavor. I just add tap water.

I've tried quite a few different "muscle" supplements, including popular ones such as BSN Syntha-6, Muscle Milk, Cytogainer (awful), whey (Designer Whey, GNC, Precision Engineered, EAS, Twin Labs, a few others...), and a whole bunch of other stuff. Well, now I know better - I've found that whey + slow release protein is the way to go.I might sound like an obsessive bodybuilder (I'm not - not that there's anything wrong with that), but as a naturally thin person who starts losing muscle mass at the slightest bits of inactivity, I find that maintaining lean muscle is oftentimes half the battle - something that I think is a problem for thin people in general.Probolic is sort of a cure-all for muscle loss. Not only does it have a chock full of fast and slow release proteins, but lots of other stuff that's great for you, including Omega 3's, CLA (which shows fat burn over time), MCTs, glutamine (I'm probably missing some)... and of course, many critical amino acids, all of which digest very well, so no bloating (unlike some other supplements). No real need to hit the other muscle supplements with this thing - one scoop per serving does it for me, but if you need it, two scoops at a time will go a long way. I've been using this for a few months, and the difference is amazing.I take a serving in the morning when I get up, Optimum Nutrition whey after workouts, and one more serving of Probolic at night. As I stated - if one scoop isn't enough, use two.The only downside is, in comparison to Syntha-6, Muscle Milk, and ON Whey, this stuff could definitely taste much better. The mixture is on the thick side (chalky, almost), which makes it worse. I recommend mixing it up with half water, half skim milk to thin it out while keeping calories in check and improving the taste. Considering how well Probolic works, though, I think it's worth it. Just... stay away from the "cookies n' creme" flavor. Stick with vanilla.If you can get over the taste - I highly recommend it.

This was my steady protein for years. Unfortunately, MHP recently changed the formula and the new formula is downright AWFUL.First, it mixes VERY poorly. It says 1 scoop per 8 oz. I mix 2 scoops in 24 ounces. With the old formula, a few shakes of the bottle and it was mixed. With this stuff you could shake for days and it's still a floating gloopy mess.Second, it STICKS to the walls of the plastic shaker bottle. Probably 20% of the product is lost because it adheres. I put water in halfway, add the power, then fill, then shake. Still there is a ton of this product left sticking to the interior of the bottle. Even rinsing it out won't remove it - you need to scrub. Ridiculous!Finally, this used to taste delicious - like chocolate cake batter. Now it's bland.Sorry, but MHP has ruined this product. And they don't respond to emails so I'm looking for a new protein.
