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.

its a great product that really help me push through my prs

its a great product that really help me push through my prs. i went from bench pressing 140 to 160 in 2 months on this product. i was stuck on 140 for ages like 6 months until i used Reflex.cons: its rubbish in taste and doesn't shake all that well hence 4 stars but does the job really well. its also a quality product and probably the best all in one supplement out there.does give some gas sometimes but not as bad as other products. i will be buying again but i would say use one shake a day not two as one is more than enough to feed your body anything else is probably going to be a waste. this way it will also last 2 months and u'll still make serious gains

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

T**.

Flavour is lacking

Although this is marketed as Vanilla Ice Cream it does not have a strong vanilla taste like a number of other protein brands I have tried. The protein content is good and the packaging is also good. The scoop that comes with the product is extremely large and quite difficult to get out of the hole whilst full of protein

Good protein being using on and off due to not having time for gym but protein is good
