NZ MUSCLE was started by Dion in 2006 and it first started in Dionβs family home while he was still a student. When the formula of what constituted a great body was being churned out and little was known about Fitness and Bodybuilding supplements in New Zealand, what was available in the market was usually either expensive or had a very bad taste formula. Prompting Dion to come up with the better-founded NZ MUSCLE. Since then the business has continued to grow, and in 2009 the group opened the first NZ MUSCLE store in Auckland, which is now developing into four stores in the city alone.
Free customs like the one NZ Muscle is indeed focused on helping people get the body type they always wanted and the health status they always wanted. Products and Services.
