The effect is there, mainly depending on how you look at the effect. Drinking muscle-building powder for fitness is only to supplement the nutrients needed by muscles with higher purity, which is also a process of gradual accumulation. If you want to drink muscle building powder and then build large muscles immediately or in a short time, I'm afraid it's not enough. It's just that people who drink will be faster than those who don't. Fitness supplements can be drunk before and after fitness, but don't rely too much on supplements. After all, you want to gain muscle mainly by your own perseverance and reasonable fitness, work and rest, diet plan.
