So I've been tasked with a research assignment and I'd like some advice from the experts here. In your opinion, what would the 3 best natural supplements to build muscle be? I've established that protein powder and creatine will be the first 2, but the 3rd I am not sure. Pre workout? Maybe in practicality because you train harder which results in muscle growth, but from a technical standpoint? Amino acids maybe eaa's? Drop your suggestions
