GNC may have a wide range of custom supplement shakers on offer already. However it has not stopped them from teaming up with one of the more notable shaker producers in the industry for another. The brand the nutrition retailer
have got together with is BlenderBottle, and their unique product the SportMixer. The limited edition GNC item comes covered in black, with brand’s logo and slogan as well as the shaker’s lid, printed in red. While there is no word on when the custom option is set to launch. The duo are giving five lucky people a chance to grab the limited edition BlenderBottle free, in a giveaway through Facebook due to close on the 23rd.
