New favourite gainer!
Definitely impressed - quality mix of protein (not filled with Soy Protein like a lot of cheaper shakes do to top their macros up!) and good sources of carbs. Range of vitamins and whilst the ingredient list is long, there's not any filler in there - just a straight up good formula! Fantastic mixability, and I've noticed a few reviews online that comment about the taste - but I had the Salted Caramel one and it tastes great (obviously I can't comment on any of the other flavours, but this one has everything I need and I'll definitely be buying the bigger tub next time and trying the other flavours!) New favourite shake, reputable brand and this listing is straight from the seller so a legit product! 10/10!

Good value and effective
Excellent product, good price. Other similar products I have tried have a sickly sweet synthetic flavour, more expensive and seemingly less effective. Nice taste that isn't overpowering or very sweet. Good consistency when mixed (I don't mix it very well or shake that much and the few clumps I get aren't at all off-putting) Despite the calories and well rounded ingredients I wouldn't think of this as a replacement and am pleased to see that it isn't marketed as such. Rather, if you are training or just generally busy with stuff this feels like an additional surplus/boost to improve your growth and overall health. I am not a big fan of protein powders, meal replacements, pre-workout etc and this feels like it sits somewhere nicely inbeteeen those. I would highly recommend this product to anyone that wants a well rounded powder to supplement their diet.

Please read review. Nice taste and mix but questionable ingredients
PLEASE READ so as a weight gainer shake , mixability and taste wise I think it's great. Unfortunately the main ingredient is maltodextrin . Which they say is a carbohydrate source , but in fact your body sees this more like a sugar and this spikes your blood sugar way more than table sugar. In fact almost double. This item for that reason will help you gain weight , but I doubt much of it would be muscle. I've given 4 stars because it's not bad , but if you are informed on ingredients you will understand maltodextrin is one you are best to avoid. Dr Berg does an interesting video on it if anyone would like a dr's opinion.

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

Does what you need!
I'm currently trying to bulk and I find these incredibly helpful. I used to use Bulk, the only issue I had was they added a thickener to their product and it made the shake so thick it made me gag whenever I tried to drink it!! With this, I usually put 3 scoops instead of the 5 and 300ml of milk and its wonderful! Yeah there are a few clumps here and there but I dont mind it as I just chug it all in one go. I struggle to eat enough throughout the day so this is great! I also use the powder to make high protein high calorie pancakes and theyre delicious! It's sealed well I havent had any issues with it so far. Ive had 2 flavours, the strawberry and the chocolate. So far im preferring the strawberry one but the chocolate isnt that bad. Great product and would recommend to others:)

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.
