I see what you are saying but for me this is an assumption of yours, until The Captain actually confirms it.
Right now, nowhere in the “Myostatin” field description does it say that it is there for “muscle growth”.
The description only says “what Myostatin does” and that the field is for “hypertrophic functions”, which is increase of the size of the existing cells.
So the field description is missing two essential parts of info for your assumption to be correct:
- That the field itself is actually aimed at muscle growth
- That the field actually inhibits Myostatin
Therefore either the field description is misleading, or the field is really not for muscle growth.
