Don’t limit yourself with simple proteins like whey. Muscles responds better to multi-source proteins. They respond to Vintage BRAWN


Vintage BRAWN™ combines fast-, medium-, and slow-digesting proteins in one mouthwatering supplement to help provide you with a sustained release of muscle-building amino acids that lasts for hours.

Vintage Brawn™ is made with:

 Milk Protein Isolate

The perfect combination of whey and casein protein sources to help provide your muscles with amino acids both immediately as well as for hours after consumption. This blended protein source eliminates nearly all sugar (lactose), fat, cholesterol, and junk commonly found in inferior protein sources to help you build quality lean muscle mass.


Egg White Protein

Egg protein is the most complete protein when compared to sources such as plant and animal protein. Egg protein has been proven to be even better at building lean muscle mass than whey. With its complete essential amino acid profile, egg white protein can support muscle recovery, growth, and strength.


Beef Protein Isolate

All the benefits of consuming a lean cut of beef, only much more concentrated and easier to digest. Beef protein isolate is perfect for those who are sensitive to and struggle with dairy. Unlike others in the industry, OSL uses fresh beef to create their BPI to help provide the highest quality beef protein isolate and amino acid profile.
