Macro partitioning

Other protein supplements (soy, casein, pea, rice, etc.) do not show statistically significant differences in muscle strength or fat-free mass gains compared to placebo in healthy adults undergoing resistance training.

If you are using other protein supplements like soy, casein, or pea protein, they may not provide significant additional benefits for muscle strength or mass gains compared to a placebo. Focus on collagen or whey if you want to maximize your results.
