I tried a tub each of vanilla and chocolate, both are very tasty. This is an outstanding product. High in protein (30g per scoop) high quality, great types of protein. I will buy again, but it is VERY expensive and not on sale often. Cost is about the only downside to this product.

Hi guys, I just cant tell you how good this product is:- Its been 32 days and I have packed on some 4kgs ( 8.8 pounds of Lean Muscle mass). This protein coupled with Insane animal type work-outs + a clean Medically supervised diet did an amazing Job. As always i'd like to personally rate it on parameters below: 1) Effectiveness : 9.5 out of 10 ( i always leave room for improvements by ON) 2) Mixability : 9.5 out of 10 ( Just 12 vigourous shakes in a shaker cup witouth any fancy ball or net is enough to get it to a smooth texture ready for drinking. 3) Flavour : Vanilla ( 9 out of 10). Not the best tasting on the market...but 32 days and I aint fed up of of it. very Light on the throat , tongue and stomach in flavour and texture n thickness.. Chocolate flavour( 7 out of 10) is a bit weird as it tasted like Chocolate, Egg and iron mixed, can easily get fed up of it.. but hey taste is matter of personal Taste n choice. 4) Price : (6 out of 10) Well I keep hunting for offers online for this one..Its pricey but i dont mind it in return for the results it provides. 5) Dosing : I take 1 scoop within 1 hour post work out..and one scoop in morning 15 mins after waking up. Hope you liked my review... REAL SERIOUS GAINS , LEAN GAINS. MY FAVOURITE PROTEIN TILL DATE... OLD PRODUCT BUT GOLD.

This has been my favorite protein powder for a few years now. Tastes great (without that weird artificial aftertaste), mixes very well, and has plenty of protein per serving. Was buying it on another site, so when they stopped offering it, I had to find it somewhere else.

Directions For Pro Complex:

SPOON STIRRED: For each scoop of PRO Complex®, add 4-6 oz of cold water, milk or any beverage with a complementary flavor. Because the powder has been instantized, all you really need is a spoon to stir the powder into a delicious protein shake.

SHAKER CUP: Bringing a shaker cup along to the gym presents you with a quick, easy way to produce the perfect shake every time. Mix each scoop of PRO Complex in a shaker filled with 4-6 oz of your preferred beverage, screw the cap on tight and shake for a few seconds.

ELECTRIC BLENDER: Using an electric blender, you can turn a serving of PRO Complex into a fresh fruit smoothie and/or stack this protein shake with Creatine and other sports nutrition ingredients. TIP: Adding a couple of ice cubes can improve the consistency of your shake.

SUGGESTED USE: For healthy adults, consume enough protein to meet your daily protein requirements with a combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program.
