The Best Place to Start with Heart + Liver.

Meet the stick we built Proven Proteins around.

Our Heart + Liver Starter Pack gives you three chances to experience a more complete kind of beef stick. Each one is fermented low-and-slow from 100% grass-finished, regenerative beef, beef heart, and beef liver, with no shortcuts, no fillers, and nothing to hide.

A touch of cracked black pepper sharpens the beef’s natural depth without covering it up, creating a bold, savory flavor that makes organ meat easy to add to your everyday routine.

Clean ingredients. Honest sourcing. A more complete flavor.

Perfect for first-time customers, travel, lunchboxes, or keeping satisfying protein within reach. For $13.99 + $4.99 shipping, it’s an easy way to experience the stick Proven Proteins was built around.

Includes 3 individually wrapped 1 oz Heart + Liver Organ Blend beef sticks. $4.99 shipping. Ships in 2-3 days.
