To be honest, Coach is dirty. You just started practicing or just practiced for a few months, so you don't need anything to drink. People who drink nitrogen pumps are professional bodybuilders. They practiced for more than ten years before their muscles reached the bottleneck. When you start drinking drinks, you just need to supplement carbohydrates. There's no need to drink this and that. People who drink protein powder every day will lose a lot of muscle as long as they don't drink it. Let's take our time. Fitness is a long-term thing! Doesn't mean you won't practice after you finish your muscles. That's no use. You should take fitness as your daily meal and sleep, as a kind of enjoyment! Through practice, you will become more and more energetic!
