For whom? If it's hard for 1/1000 people, this doesn't mean much for 999/1000 of the people reading this. But I doubt you meant 1/1000, because you wrote this:

Saying "it's not the case for everyone" logically implies that for at least one person this is not the case, but that's it. Yet, I doubt you'd clarify these two sentences if you thought only one person (or a handful of people) experienced these differences, so obviously you have some kind of degree of frequency in mind.

"You don't need to have extreme cases of myostatin variation" just shifts the question to the degree of variation of effect instead of degree of variation in levels -- "it may not vary wildly, but you only need a small amount of variation to have an effect."

This still would not specify how much of an effect. It could have an effect, but that effect could be a 1% rate reduction.
