Visalus offers fitness and weight loss products. They carry shakes, snack packages that can be purchased in the form of various kits for weight loss, energy level improvement, and fitness purposes.
This company is most known for their Neon energy drinks.
This seems to be also a company doing direct sales of products.
This website does not list their prices until you proceed with the registration, which I did not complete, therefore the prices are not clear – let me know if you know what these kits sell for!
