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.

Feel power

Nice power after drinking it.But taste it’s not all that (cookie and cream) doesn’t taste at all , but effective powder

J**E

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 👍

I think it's working.

Flavour is fine. I've started lifting and taking these, and I've gained muscle. I don't know how much the protein powder matters compared to how much lifting matters, but the combination of them definitely works.
