Our sponsored athletes bring discipline, dedication, grit, and all-natural strength to their training regimens. Our national competitors-- Ryan Propst, Lloyd Chambers, Joe Toth, and Alex Atanasov-- have consistently performed at the highest levels across the United States at NPC World Bodybuilding Events, or, in Lloyd's case, on the most demanding bike trails known to man. The Beef Authority is proud to sponsor them.

WHY USE THIS BEEF PROTEIN? Supplements have come a long way in the past few decades. Protein, especially WHEY protein has stayed relatively the same. Now, I am not badmouthing whey protein. I still use it. As long as it is made by a reputable company, but this BEEF PROTEIN is on a whole new level. It has a unique amino acid profile that compliments and works with whey and is far easier on the digestive system. This protein never makes me feel bloated like dairy sometimes tends to do. I have tried dozens of proteins throughout my life. I have been in the competitive scene for over a decade now and have been training for over 30 years. Being a drug free for life bodybuilder, I have to be on point with nutrition and good supplementation. This is my all time favorite protein. I used this protein and only this protein for my last show and produced my best look to date. It helped me hold onto more muscle as I dieted and helped keep my strength up. If you are going to put the hard work in at the gym. Make sure you supplement with the best protein available. Remember, training is only half the battle. Nutrition, rest and proper supplementation is crucial if you want to build the best version of yourself possible.

Primal Feast seems to correlate strongly with regaining muscle strength and never upsets my stomach. While I use and mix several protein sources, my go-to protein after a double century or hard workout is Primal Feast as the dominant protein source.

Primal Feast is the staple of my contest supplementation. In order to repair and build muscle my body needs the best ingredients to make this process happen. Primal Feast taken before and immediately after my workout provides the perfect combination to help me get in the best shape of my life.
