Insane Labz PROLEAN was formulated to go beyond traditional whey protein by incorporating a premium hydrolyzed bovine collagen protein matrix designed to support connective tissue integrity, joint performance, and structural recovery. Each serving delivers 26 grams of protein with 110 calories or less and 0 grams of sugar — a highly efficient protein source for athletes focused on performance, recovery, and body composition. What separates PROLEAN from standard protein formulas is its emphasis on collagen-derived peptides. Hydrolyzed collagen is enzymatically broken down for enhanced absorption, supplying key amino acids involved in the formation and maintenance of connective tissues throughout the body. Collagen supports tendons and ligaments under heavy training stress, joint mobility and structural resilience, cartilage during high-impact exercise, skin elasticity and structural protein maintenance, and connective tissue recovery after intense activity.
