No, bodybuilders should do their own research or buy a thick textbook on nutrition and find out things.
This is a forum where we all have opinions. No one changes what they believe about training or nutrition no matter what.
People really are sheep when it comes to beliefs. Yet they are quick to attack others. wtf is that?
"No one changes their opinions about training and nutrition?" Really? You're saying I have not change my thinking one iota in the last 45 years that I have been involved in resistance training and nutrition. Speak for yourself, my friend. This whole thread started because someone found a novel way to ingest protein powders and possibly alleviate a very common problem. The salient feature in your posts is how you accuse others of doing exactly what you do: dogmatic, lack of scientific research and references, zero proof, constant attacks. There are few here that read your posts and complaints and not say, "Wait a minute! That's what YOU do!" You yourself mentioned that I have cut back drastically on my protein intake and you played a part in changing my thinking. I've gone from 300g/day to about 90-100g/day. I completely changed the way I approached calf training and transformed my peg legs into my most "prominent" (as my doctor recently described them).
It seems I've gone through a lot of variations of training and nutrition over the last 40 plus years. And I'm still at it. When was the last time you went to the gym consistently for a least a month?
Marty Champions is an extreme example of one constantly experimenting on nutritional protocols.
No one changes their thinking? No one exemplifies a fossilized mind such as you do. And that's not an attack but a statement of fact with your own posts as concrete proof. And I know you will not give a nano second for self reflection. I believe you have a reach a state in life that your brain simply lacks the ability, not to mention desire, to ever question yourself.
Like I said, speak for yourself.
