I have been using this protein for 2 weeks now and I can say that the results are great! I noticed an improvment in my strength when doing workouts, and also lost about 2 lbs of fat - it shows in the mirror :) will keep with it
A top product for losing weight, before the holiday I needed a little help in shaping my figure and I can guarantee that it really works :)
I am working with clients for over 5 years now and in that time, I have tried a lot of different protein powders. After using this blend I really noticed a difference. I started recommending it to the clients that are looking to shape their body faster - the results speak for themselves.
Made from quality ingredients
Whey protein is a high-quality protein source commonly used to support muscle repair and growth. It contains essential amino acids that help maintain muscle mass and contribute to adequate protein intake.
Rice protein is a protein powder obtained from rice. It is often used as a plant-based alternative in sports drinks and dietary supplements.
L-carnitine is an amino-acid derivative that plays a key role in fat metabolism in the body. It is a natural compound produced by the body and can also be obtained from certain foods and dietary supplements.
Guarana contributes to fat metabolism and suppresses feelings of hunger and fatigue, making this natural extract an effective aid in weight management.
Vitamin C helps protect cells from oxidative stress, supports the nervous and immune systems, and helps reduce tiredness and fatigue. Vitamin C also contributes to normal collagen formation.
B-complex is a group of vitamins—B1, B2, B6, B12, folic acid, pantothenic acid, and niacin—that are important for our nervous system. In addition to their shared function, each B vitamin has other important roles in the body.
