Macro partitioning

When protein intake is matched for quantity and leucine content, plant-based protein supplements produce equivalent gains in muscle mass and strength compared to animal-based protein supplements during resistance training.

If you are training to build muscle, you do not need to buy expensive animal protein powders. You can use plant-based proteins (like soy, pea, or rice) and get the same results, provided you consume enough total protein and ensure the supplement provides a similar amount of leucine as animal sources. Match the dose (e.g., ~25g protein) and train consistently.
