Review: Great product. - Not a food person in the morning so this works great. Good taste and mixes well. Not gritty, good value and feel much better after a few weeks. Can't comment on gym use as I don't go.
Review: Tasty, helps put on weight and mixes well - Husband loves this! He has purchased this 3 times now, uses it in between meals and on days where he’s out for work and doesn’t have time to grab something to eat. It’s been great for helping him put on weight. Really lovely flavour and mixes well with water or milk, unlike other reputable protein shakes that have a strange after taste and texture. The 5kg bag lasts a while, so definitely worth it and it comes in an easily resealable bag with a scoop. Only down side is the sugar content is very high! Also the recently price went up, which is a shame as had bought it around £28 couple months ago.

### ⭐⭐⭐⭐ Decent stuff
*by B***N on 4 January 2024*

Just starting off at the gym again trying to bulk and this definitely has helped, it's impossible to get a full serving into one shaker so I have to do it in 2. This isn't a milkshake from your local restaurant so don't expect it to be tasting like so. Taste isn't the greatest but definitely isn't the worst. But I'm not using it for taste so it is what it is. I've put on around 8/9lbs since using it over the past couple months (had a period where I stopped using it) if new to this then start off with half the full serving for the first week as going all in with a full one can cause stomach problems (bloating, wind, nausea etc) im taking along side cyclone, at different intervals, obviously, and also only using cyclone every other day. It's not no miracle shake, so don't expect unrealistic results, eating a full breakfast, lunch, dinner and snacks in between then this and hour or so before bed has worked for me. Can't really say if it works for performance as I'm still figuring that out myself. Will update once I know more but so far so good.
