First of all i have to say thanks to this site, i wouldve never found this amazing product without it.

Taste: 8/10 I got the Rich Milk Chocolate, standard chocolate protein taste more or less like hot chocolate mix.

Effectivness : 10/10 I absolutly loved the gains and recovery i had on this product. I used this for PWO and in the mournings amazing.

Value : 7/10 A little pricey but not overpriced gains are great.

Overall: 9/10 You cant beat the profile on this, effective and decent value.

A great protein to start out the day. I use it once I get up and it really kicks my body into an anabolic mode. It assists in recovery post workout, assists in building muscle, helped boost my strength, is one of the better tasting proteins available, and it mixed great in a shaker cup. The only negative is that it is pricey but you are definitly getting what you pay for.

I've been jumping from protein complex to protein complex and I finally landed on this one. Best purchase I made in awhile. The complex proteins make it great for digesting after a workout. Hits you fast, works for awhile. Rocky Road was my favorite flavor. And 60 grams of protein makes it an awesome drink after an intense workout.

My personal favorite protein. This blend is one of the best. Rocky road is the best flavor in the line up. Its slightly high in sodium due to it having high amounts of expensive egg protein in it. Optimum didn't skimp with Pro Complex no sir, it has a wonderful profile and works great b4 a bodybuilding competition. It's a serious non hyped top of the line blend. I will always use it.. Love it.

I finished a tub of this and i have to say it is really great. I really saw strength gains and i was able to bulk up without feeling the bloated feeling of a weight gainer. I totally Reconmend this product for anyone who needs to add protein to their diet. This has 60 grams and all of them get used with fast,medium,and slow proteins. My body felt great the next day after a workout aswell. This is worth any money.

What can one say about ON, if you've using it you have a leg up on the guy who isn't, ya know? I used to use Whey Standard because it's the best protein you can get for the price. I recently switched to Pro Complex (get a discount through work, woot) and wow, I hope I never go back (but if I do, it'll just be to Whey Standard :)
Pro Complex has fast, med, and slow absorbing protein, can be used in the morning, before/after workout, and before bed.
Clean protein, not pages of nutritional info like MuscleTech, etc...
It's the first protein I've tried that actually tastes pretty damn good, amen to that alone.
Mixes super easy... What else can I say... I don't really notice any difference in muscle gains as I'm still going through a phase of trying different kinds of proteins. Currently using this in conjunction with MuscleTech Hardcore. Hardcore tastes like sh*t in my opinion, but that's just me.
Oh, Pro Complex is incredible low in fat/sugar as well (beats Gold Standard).

Pro M'Fing Complex. Before I started on this site I never even heard of this stuff, the only reason why I even bought a container was because it's rated so high and I gotta say it's worth the rating. First things first the fact that there's only 60g of protein and only two scoops with hardly any sugars and carbs and what-not blows my mind. The weight gains were very impressive with two of these shakes a day my protein intake is now 270g a day I couldn't be happier. It mixes well and although it's not the best tasting protein I've ever sipped on it's def not the worst. The price isn't to bad either I've noticed most protein isn't cheap anyway. Pro Complex has made it's way into my diet and I doubt any other protein will take it's place. THANKS Optimum!!!!

This protein is hands-down the best whey shake I've ever taken. Here's the review:

Taste: 10 of 10. Dang, this, in my opinion, is about as good as a protein shake will ever taste. Add some natural peanut butter and a banana and you just might think you're drinking something from Baskin Robbins.

Value: 9 of 10. You can find cheaper whey supplements, but I doubt they'd taste or mix better.

"The Mix": 10 of 10. About 3 or 4 shakes of the mixer cup and the blend is pure liquid. That's nuts. I can remember my first whey protein I took. It'd take a blender to mix that junk up. Every once in a while I'd get a chunk of whey sliding down my throat and it'd make me almost throw up. But, no problems with this. It mixes easy.

Aminos...this stuff has plenty of them.

Overall, in my opinion, this is the best whey supplement on the market. But still, nothing's perfect, so all 9's.

Awesome, great protein blend! It has all the things you need, I take it in the morning now instead of just 100% Whey so I can get the slow release proteins as well. Stacked this with 1 MR, 100% GS Whey, Pro Complex gainer, Halo(i know, i know), ON ZMA, Fish Oil, multi, and a green tea.
Strength through the roof, allows me to hit it hard every workout with little to no soreness, and I am doing 6 on 1 off! It allows you to make the progress which is all you can ask out of a product. I love it!
I am going to finish my 100% Whey and make this my and the Pro Complex gainer my new protein sources at all times of the day. It mixes and tastes awesome. It mixed so well I just put this in one of those dollar general 1 qt bottles so I could use my shaker for halo.
This did so well in my recovery i am going to eliminate the halo and I just purchased Prime and Pink Magic. Looking forward to seeing if this can keep up with recovery! Because I know I am going to push each and every workout to the limit. Thank you Optimum Nutrition for all that you do!

Great product. My first choice for a protein supplement. The taste is good but not the best tasting that Ive tried. Definately the #1 choice for me right now.
