Why are you so opposed to there being bodybuilding secrets? Of course they're insights but that doesn't mean they aren't also secrets. As I already explained to you, if nobody knows it isn't it a secret? I can guarantee you there are many bodybuilding skills you haven't mastered yet so to you all those are indeed secrets. If you take this weight gainer like Mr Olympia does, there's no reason why you can't be Mr Olympia too since you're both on the same stuff. Plus, as it says on the label, it's for athletes only. Do you qualify to take this elite sports supplement? 
I hope that bold part is written in a sarcastic mode, right? If not, you don't know where you're talking about.
There are as many insights as the number of people who are involved. No need to explain that you can't master them all.
We all know the rules of thumb to become successful in bodybuilding: quality drugs, training, food, sleep, good genetics and only a couple of supps. All these subjects have been discussed to the T, so you better start executing your game plan before you get to old from reading all those 'secrets'. No hating here, just giving my honest opinion.
