Rhinomed Limited has announced further expansion of its North American retail distribution footprint having received confirmation that its Mute sleep technology will go on sale in 811 GNC Holdings Inc. health, wellness and performance stores. The GNC deal will see Mute rolled out as part of a trial in corporate GNC stores across the continental United States. This also includes over 140 stores located on military bases. The trial will see Mute trial packs located in a clip strip program in the sleep section of these stores. Sales performance will be assessed on a store by store basis. If successful, the company anticipates a staged national roll-out. The Rhinomed North American team will actively assess store performance throughout the trial and has a marketing program in place to further support sales.
