Why do we offer this product? MYOBAND introduces Marvel Studios to your life bringing your favourite Superheroes, such as Hulk, Thor, Spiderman, Black Panther, Ironman and Black Widow, in the form of a unique shaker, enabling you to produce the perfect shake every time. Enjoy the drinking experience demanded by an Avenger! How is the product unique? Each shaker is totally unique with fully ‘Marvel’ licensed artwork and iconic design. The only decision you need to make is which supernatural power to use! If ‘Hulk Smash’ relates to you, then we have 2 different Hulk protein shakers - Avengers Hulk and Traditional Hulk! More of an 80s nostalgic kind of person? Then why not go for the Star Lord protein shaker or go for one of the original avengers in the comic series, Ant-Man. Why use a shaker for your protein powder? Quite simply a protein shaker is used to mix your protein powder with water and milk. You can of course mix in any container with a spoon but the issue is the amount the protein powder dissolves. Through the use of a spoon to stir and mix there is the risk of lumps which not only make consuming your protein shake more difficult but can also result in some of the powder settling at the bottom of the glass. The protein powder that is left means that not only has some of your powder been wasted but more importantly that you have not had the full protein. A shaker is designed to mix powder and liquid which increases the amount of powder that is dissolved and the amount of protein you consume. What are the benefits of the Marvel shakers?
