The real athletes are not taking a million different things every day
I took just about everything in every combination, I looked my best on a natural human diet and 250mg of test a week. The biggest I got was eating white fish and rice and taking 1g of testosterone a week - nothing else. No creatine no protein powder no BCAA no other nonsense
Now I'm older and wiser I know that most people just need to eat more natural food, more calorie dense food and do wayyyy more volume (Time Under Tension near failure) than they think they do. Thankfully I realised this 5 years before I enter my physical prime
