Tastes great no crappy aftertaste
Just bought this Strawberry and CreamFirst of all it smells amazing .I'm getting old (55) and I'm an extremely busy person ... i don't go to the gym never have never will and bought this as additional calorie intake.1st impressions .... you will need a massive shaker to fit in a full serving .I ended up doing 1/2 serving with 500ml of water twice.It mixes absolutely fine with no clumping ( I did only add a little at a time to the water )Tastes absolutely fine with no crappy after taste .No complaints

Muscle building Gainer
Brilliant weight gainer for muscle building. Has a great protein profile. The quality of the product is very high and well packed. Although it has huge serving portions you can always adjust to what you need to meet your requirements.It dissolves well and tastes really good compared to a lot of others I’ve tried. It has a smooth texture after just a few shakes in a bottle and goes down nicely.

It's very effective
It's effective but it's not magic. You have to be consistent with it. I added extra weight which I wanted, after a few weeks. Prompt delivery. Well sealed. The protein quality is good. I mix mine with milk. It doesn't upset my tummy. It has a good taste.The only reason I didn't rate it 5 star is the packaging.

This is like Optimum Nutritions sibling.. It's amazing
I was going to get Optimum Nutrition but I saw this for a cheaper price and the way it has been advertised and the name I just wanted to try this. And believe me this is something to pick up if you want a lot of protein. I chose the strawberry cream flavour and some reviews say it's a bit sweet and I agree but the sweetness won't take you away it's a great add on. You don't want to taste a tasteless shake right? Next time I'll get the chocolate one as apparently it's a better flavour. But Reflex Nutrition know what they are doing. I'm also buying the Whey Pro soon too! And the scoop is pretty huge. Enjoy it while you can.

Absolutely stinking !
Don't buy this, it tastes disgusting and there is no way there's 1000 calories per shake. Tastes like sucking watery plastic through a strawberry.I've used many weight gain powders over the years and a 1000 calorie shake is usually hard to drink due to its thickness, this is hard to drink because it's disgusting.I think this is being sold with misleading info. Personally I doubt I'll even bother to finish it.Also the tubs only half full which in hindsight I'm happy about as it's awfulAvoid

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.

Problème pour refermer le produit après ouverture
Le fabriquant aurait pu faire mieux .Le système de fermeture du produit n est pas efficace. Je vais être obliger de le changer de contenaire. Et le gout n esr pas top sachant que je ne suis pas difficile

Prodotto buono, piccola pecca
Spedizione rapida, gusto ok, ottima digeribilità, unica pecca quando lo si mischia nello shaker con l'acqua diventa tutto schiumoso e ci vuole tempo per berlo, un po meno con il latte
