[OUR VERDICT]
Transparent Labs wins with 28g protein per serving, superior taste, and better protein-to-calorie ratio, making it the premium choice for serious athletes.
After extensive analysis and real-world testing, Transparent Labs emerges as the superior choice for most users seeking premium grass-fed whey protein. The decisive factors include its consistently higher protein content (28g vs 21-23g), superior protein-to-calorie ratio averaging 86% across flavors compared to Legion's 78%, and exceptional taste quality that earned perfect ratings from multiple testers.
Transparent Labs' commitment to transparency extends beyond marketing—they deliver measurably higher protein density in every scoop, which translates to better value despite identical pricing. The smooth mixability and wide flavor variety (18 options) make it more practical for daily use, while maintaining the same high-quality grass-fed sourcing and third-party testing standards as Legion.
Legion Athletics remains an excellent choice, particularly for users who prefer the unique Irish Truly Grass Fed™ certification and don't mind the variable protein content across flavors. Their Sustainable Dairy Assurance Scheme certification and smaller farm sourcing appeal to environmentally conscious consumers. However, the lower protein density and occasional mixing issues prevent it from claiming the top spot.
For serious athletes and fitness enthusiasts prioritizing maximum protein intake, muscle building potential, and consistent quality across all flavors, Transparent Labs provides the better investment. The 25% higher protein content per dollar spent, combined with superior taste and texture, makes it the clear winner for long-term supplementation goals.
