And the taste? Let's just say, if all healthy things tasted this good, junk food would be out of business. Plus, it's got that perfect protein-to-calorie ratio, so you can get jacked without feeling like you ate a whole pizza. Basically, it's like getting all the gains without any of the guilt—what's not to love?

Shaking all over

Quality is not cheap! Mixed in manual bottle shaker with tap water results are great. As for those who use blenders WHY! If you have not gotten the energy strength to manually physically shake a proper protein mix then this is Not for you. If you after a no fuss quality protein ie put a scoop worth into 250ml water and shake for ten-15 seconds and drink with no lumps and taste great then here you go. This is a quality protein mix all their protein powders are! Not cheap but neither are the ingredients that they use.

Absolutely love this - superior quality and gorgeous flavour. Such a shame it's expensive but you can't skimp on good quality protein. Essential for snacks or post-workout. I also add some powder to my yoghurt in the morning it's pretty versatile!

Pretty good taste

I have to say I generally find premixed protein shakes have a better texture and powders rarely taste as good. However, this is quite nice, makes a nice thick shake that's quite sweet. I don't get a buzz from the caffeine, but it does help muscle building combined with targeted weight training, and is much lower in calories than other lines. The packaging has changed since I last used Promax Lean, but it's just as good. The only criticism is it's quite expensive and if you're taking the recommended 2 portions a day it'll only last two weeks (but good protein shakes are always pricey).
