Sad but true - no,longer value for money

Just bought the new clear protein (incentivised by the free creatine). Good change from whey with a nice clean taste. Originally looking to buy Gold Standard but at nearly £100 a tub that was a no go. Sadly after nearly 20 years I am now having to explore other protein powders.

Really liked the Milk Chocolate flavour…

Really liked the Milk Chocolate flavour — tastes good and mixes well. What I liked most is that it feels very light compared to many other protein powders, so it’s been easy to include in my daily routine. Overall, a very convenient protein option.
