The ultimate goal of every bodybuilder is to build muscle mass while keeping body-fat percentage low. Sports nutrition science tells us that doing your best to support muscle tissue is, in itself, a valuable fat-loss strategy. This is because muscle is more metabolically active and may improve calorie expenditure, thus supporting further fat loss. Therefore, maximizing protein intake throughout your day is essential.

A Uniquely Transformational Protein Technology

However, not all proteins are created equal when it comes to body repartitioning. One protein, in particular, ProSource’s Vectron®, contains an elite fractionated protein complex called Prolibra, a specialized bioactive peptide matrix along with a special whey mineral complex designed to precisely target essential mechanisms of body transformation.

The patented protein peptide fragments found in Prolibra® are specifically designed to enhance satiety by helping to stimulate the release of the hormone CCK. CCK is a hormone that is sent from your digestive tract to your brain letting your brain know that it needs to turn down the hunger signals. Meanwhile, Prolibra contains milk mineral complexes aimed at optimizing calcium levels within fat cells to yield maximum efficiency with regard to weight-loss support.

A Clinical Test of Vectron’s Key Active Ingredient Delivers Exciting Results

How effective is the weight management technology in Vectron protein? Let’s take a look at the science. In an independent, randomized, double-blind, 12-week clinical trial published in the Journal of Nutrition and Metabolism, test subjects showed significant improvements in the ratio of lean mass to fat while taking just 24.4 grams of Prolibra® per day compared to a control group taking an isocaloric placebo. The subjects taking Prolibra® retained twice as much lean muscle with 79% fat-loss compared to the control group at 51% fat loss. Prolibra® is highly exceptional in this regard, as no other protein complex has been clinically proven to achieve this type of body composition improvement in a 12-week period (not to mention at such a modest daily dose). Remarkably, the Prolibra® group, using just 24.4 grams per day, lost 6.1% fat.

Vectron is a very exciting physique enhancement tool that has made the ultimate goal of simultaneous muscle support and fat-loss more of a scientific reality than ever before.
