Mike Chang Fitness as the direct manufacturer is offering a special limited time offer promotion on the product. Rather than having to pay the $97 retail price on the formula for a one month supply, users are able to obtain it from him directly at $67 per bottle. To do this, users must agree to sign up to an auto enrollment program that will see the formula shipping out every month to their address. Besides this, Mike is offering a no extra charge bonus product to be included with the shipment called Monster Mass, his greatest muscle building formula yet. This product increases muscle mass growth faster than any other means, per Mike Chang.
