## Description

Applied Nutrition Critical Mass Professional - Weight Gain Protein Powder, High Calorie Weight Gainer, Lean Mass (6kg - 40 Servings) (Chocolate) : desertcart.co.uk: Health & Personal Care

Review: Great tasting and effective - Bought this for my partner who is very ill, has no appetite, had lost a lot of weight, and needs extra nutrition and calories. This product is effective and delivers on both fronts. It has no particular smell. Easy to use, it blends nicely with any other ingredients you may wish to add to your shake. It mixes well in a blender and has a great, smooth and creamy taste on its own. Since my partner is in dire need of vitamins and minerals I also add some frozen spinach, carrots and some fresh fruits to his shake. For calories, I top it up with some peanut butter and Nutella. It may seem excessive, but he splits this shake in half and drinks it twice a day with his medications. In one month he gained a stone, which I was very pleased with, though he still needs to gain more weight. His blood work shows improvement in all areas. Because of all other things I add to the shake I use about 1.5 a scoop , which is enough for our needs. The tub is very big, and with 2 scoops a day it will still last for at least a month. It may seem a bit pricey, but considering the quality and how long it lasts, in my opinion it is a good value for money. When it comes to the size of the tub and the amount of the product in it do not make a mistake of thinking that there is some product missing. I don't believe there is. The fact is that all products in powder form settle down once packed in a tub and visually go down in volume after a while; what matters is the weight and that it remains the same as it was at the time of packaging. If you have doubts, which I don't, I suggest you weigh the powder before coming to a conclusion that there is something amiss. This was my second purchase of this protein and I am so satisfied with its quality and performance that I intend to continue buying it for my partner even after he recovers.
Review: Great tasting protein shakes - This is great stuff, results are better if you use up the full tub.
