Review: Good value - Requires a very large cup full of powder for the serving advertised so be aware the flour is decent not bad at all this is my 3rd purchase it’s good value
Review: Shame on price increase robbery - This is the best protein shake I’ve ever had, it has everything in so it saves me buying loads of extra sups and I’ve used it for over 20 years. However… since last month Reflex have increased the price by £20+ per tub!!! It was £50, and now it’s £72!!!! Absolute scam thieves!!!!! Never again will I buy this. I’d rather buy multiple sups than get robbed. Shame on you guys ! You lost a bloody loyal customer! I always bigged you guys up to mates, colleagues and other gym users.
