It seems like it's always bodybuilders that will swear by/try anything and everything under the sun, but never any other athletes, and yet somehow, they get by just fine. Bodybuilding wasn't changed by any supplement, but rather by Dorian Yates bringing a whole new level of roid usage into the game and more effective roids/the rise of HGH/insulin abuse.
You've obviously have never been around elite level athletes. I've spoken to a certain infamous Canadian Olympic gold medalist. They would take anything if it meant it would give them an edge.....but first the stuff has to actually work. They spend thousands upon thousands on all the illegal/dangerous stuff, so it's "simple economics" that a 40 dollar bottle of AmentoMax will break their bank? I guess they prioritized their finances wrong.
All the effective supplements like creatine, caffeine, whey, etc. have stood the test of time for a reason, bc they are simple and they work.
I've said my piece, I'm not going to argue with you. It's your life, your body, your pocketbook. Do what you enjoy and works for you, as long as you enjoy doing it, bc life is short.
