This is a highly effective Lean WPI from Genetix Nutrition that gives you one of the highest quality, ultra-flow filtered, Whey Protein Isolate (WPI) available in the market. WPI is an easily digested protein that is quickly absorbed by the body. Lean WPI is ideal for individuals that require maximum muscle growth, has virtually zero fat or carbs and is rapidly releasing.

Over the last few years, Genetix Nutrition has always utilised New Zealand WPI. The brand continues to produce a quality product utilising one of the most effective and ethical WPIs on the market.

Genetix Nutrition WPI: A superior protein delivery

Not all WPIs are equal. Some WPIs are manufactured under harsh conditions and are robbed of much of their bioactivity and thus become less effective. This Lean WPI by  Genetix Nutrition is carefully processed under strict conditions to ensure it maintains its high level of naturally occurring essential and branch chain amino acids. This lean WPI is one of the ultimate in lean proteins on the market for the elite competitor or health-conscious individual.

So why use WPI?

One reason is that it is high in BCAAs for lean muscle growth. WPI also supports the body's immune system. WPI contains high levels of essential amino acids. Genetix Nutrition Lean WPI is nature's purest and most effective protein for supporting lean muscle gain as well as maintaining overall health and fitness.

This WPI is purified and Genetix Nutrition does not use Ace K or aspartame in the product. It contains naturally occurring immune boosters and antioxidants and is a natural appetite suppressant. Elite bodybuilders, athletes, fitness enthusiasts and everyday gym-goers are moving to Genetix Nutrition's Lean WPI because of its benefits as a high-end protein source.
