Excellent stuff, i have done my webwork checked out ...
Excellent stuff, i have done my webwork checked out levels combo's of minerals and bcaa's through to creatine mixes this stacks up seriously good easy to mix good strong flavour but not sickly easy to consume on an empty stomach and has nice milkshake consistency. can easily be drank in the morning and pre workout and after the workout again great levels of bcaa and creataine as a stand alone this can save you money as it contains everything you need in one supplement and it really has shown results after consumption after a good workout. can only recommend this as it does exactly what it says. any questions drop me a message

Poor packaging lid tampered with
The product itself is great but today’s delivery not so much. The box was absolutely battered and open and the kid was unscrewed on the tub

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 👍

Taste is worse than others i've tried
Bought this on the back of the strong reviews. The taste is really not great. It's very sweet but this is the case with most meal supplement shakes. The Strawberry and cream flavour is strange; it tastes like strawberries, cream and another flavour which i can't quite put my finger on, but really isn't enjoyable.
