The same brand can be extended to different types of customers....Like Nordstroem Racks for those that prefer shopping at an outlet versus Nordstroem Department store for those that prefer shopping at an upscale Department stores.....both types of customers get the experience they look for....
So, Musclepharm should have done it this way:
Iron Whey Green is a high grade whey protein for the pros.
Iron Whey Blue is a lower grade whey protein for everybody to afford.
Investors love seeing such branding strategies....it shows that the company manages its costs very effectively and it shows that the company serves as many customers possible as their terms.
