would def buy again (banana) (not white chocolate)
i bought the banana and white chocolate. i personaly like the flavour of banana and would most likely buy it again but next i will buy another flavour to just test the favours. white chocolate personaly just does not taste that good, its not bad but its not good. really does not taste much like white chocolate but its fine. white chocolate bucket came a lot fuller than the banana not sure what it was. mixability is not the best as if u let it sit u get bits at the bottom so i shake it up and then drink a lot and when i go to drink it again i shake it up so the stuff is throught the whole drink.there is never any lumps tho is which is good. i personally like to drink big protein shakes so taste needs to be nice and the favlours are good. the serving size of 3 scopes makes the protein shake good and so after drinking i feel full which is very nice and i would def recommend buying this as it is super cheap

Not good at all!
First negative review I've had to post up (usually just throw whatever it is away and get on with things) had to leave a review on this. Absolutely terrible product Doesn't mix properly at all, stays gritty no matter what you mix it with or how long you mix it. Supposed to be Banana .......just has a really strong chemical taste. Basically had to force it down everytime i used it whilst trying to stop myself bringing it back up straight away. Started feeling quite unwell so i gave up after 4 days of trying and threw it in the bin. It's now the day after I stopped using it and I feel fine again - 5kg Banana flavour (apparently)

Is it worth the faff?
I've used this protein since early 2023/ late 2022. In conjunction with a decent diet and exercise I've gone from 58kg to around 78kg, I've not gone as hard as I could have and there's been some time of due to sickness, but my point is, it works. It does what is says on the tin. It's protein powder after all. So you may be wondering why the 3 star rating, WELL. - Every flavour aside from Banana is so overpoweringly artificial in its smell and taste that it made me gag. After about 2 weeks the taste and smell fade enough that if you're not as stubborn as I am, and force yourself to drink it anyway, you'll be able to stomach it by then. - Taste and texture is inconsistent from tub to tub. - I have found what appears to be shredded plastic wrap in one of my tubs. My latest tub arrived open and covered in powder, and for whatever reason, this is the point at which I decided to contact customer service, only to find The Bulk Protein Company has closed their phonelines and replaced them with an AI chatbot, because of course they have. So while I await a reply from Customer Service, If I even get one, I figured I would finally review it. It works, but whether the savings are worth putting up with the surrounding issues I leave up to you.

Really good protein
I was on a journey to find the best protein shake out there and needless to say I think I have.. let's break down the product... I tried with water didn't taste the best but I've had worse... But I mix 3 scoops with milk and it tastes absolutely fantastic.. mixes really well hardly any clumps etc . My mission was to find a product I can look forward to taking consistently etc. Well I have 2 shakes every second day so my body doesn't get immune to it... And it really does do wonders... I got banana one haven't tasted the others and I probably won't.. because don't fix something that isn't broken.. I have 3 scoops and before the milk goes in it already fills half the shaker.. tbh it mixes that well I reckon you could do 4 scoops if you want an extra bit of protein.. but more than 30g does me fine with a nice eating plan.. if first time buying this stuff I'd definitely go with banana.. also I use a protein Shaker with the separator on top and the whisk ball inside. I shake for about a minute and it tastes good and isn't really chalky or thick... If you are starting out this is definitely a good starter for all eager gym goers.
