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.

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.

Buy it.
This could be life changing! Been trying to bulk for a while and always become inconsistent with it, this just keeps me on track so nicely. I recommend splitting the “serving into 2” to reduce the density. So have 350ml water/milk and then 1 scoop and do that twice so maybe one morning, one evening. Makes even MORE drinkable. It’s worth the money just for the fact it keeps me hitting 3500kcal everyday without much effort.

Damaged
The Protein powder itself is great and I’ve bought repeatedly but on this occasion the bag had split inside the box and lost a lot of the contents. A replacement would be much appreciated.

Decent stuff
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.

Excellent
I bought this for my son who is not a gym lover but is a manual worker (Plaster/ builder) who finds it very hard to keep wieght about him, he finds this keeps him healthy with a good gut, it is very good value for money smooth when made up with a nice flavour. I will be buying again

Ffs.
Bought this as I couldn't get my normal order. This shake is awful! Got the chocolate flavour, it does not mix in a shaker. There was a good half a scoop clumped in the bottom. I put it in the blender and obviously it sorted it. Taste test time. Wish I bloody hadn't. It tastes somewhere between plastic and petrol. DO NOT WASTE YOUR MONEY. I will deffinetly pay more attention as to when I'm running low on my usual stuff. Fyi - MUSCLETECH MASS TECH EXTREME 2000 is the one to go for. Mixes perfectly and tastes amazing. 10/10

Good value working mass gainer!!
Products great, gives you ample amounts of calories, carbs and protein if your looking to put on mass!! Ive gone from 86kg to 96.5kg in two bags which ive spread out and has lasted me for 3 months using on a 3 day on 1 day off training schedule after training and i often only use half to 2x 3rds of a scoop!! Its easy to mix with water and tastes alright. Ive brought a couple of theses now and this ones packaging and delivery box was unappealing and worse for ware, but no harm done!!

gutes Produkt, leider falscher Geschmack, freundlicher Kundenservice
Mein Freund hat das Pulver über meinen Account bestellt. Er kennt das Produkt und ist von der Qualität überzeugt. Leider wurde entgegen der Beschreibung eine andere Geschmacksrichtung geliefert. Bei Reklamation hatte ich jedoch einen sehr freundliche Kundenservice und konnte es ohne Probleme zurück schicken.
