Great taste
I do love this product. It does what it says. Has a great taste too.I drink of this a day on top of my food is enough to put some weight on. I scored this 4/5 due to the product making you smell of milk. Strange I know but you can smell it on you / in you (I guess through your pores) for hours afterward.

A good meal replacement, especially post workout
I think this is a very good product. It mixes nice and easy, smells good and provides sufficient calories and macro nutrient content. You'll get a good size tub for the money which I think makes it pretty good value, although if you were going to take two shakes a day, you would find it quite expensive. I personally didn't experience any stomach issues, but this is a heavy product with a lot of ingredients so some people may find they do. Obviously an item like this is designed to be taken over a long period of time so I cannot comment on its effectiveness but used correctly it would be an excellent addition to any regimen.

Unacceptable Taste
This product has good value for money; however, the taste is too sweet and unpleasant. I couldn't finish it without mixing it with milk.

You’re best training partner!
Reflex use grass fed hormone free milk to produce the protein in this plus the creatine is the purest available in creapure, complex carbs oat & barley flour plus lots of other stuff to really give your workouts the power & energy you need..not taken this for a few years but within a day or two i definitely had more power & strength lifting weights. This is very sweet though.. maybe it’s the combination of sucralose, stevia & maltodextrin but really I’m mean even for me it’s too sweet, I’d omit the artificial sweetener personally you don’t need it. This supplement is to my mind comparing it with other all in one’s the best in terms of ingredients & results... REFLEX 👍
