Break the Matrix

I know this thread is kind of old but I agree with it. As an adult if you want serious bone changes go for surgery. From what I've read the bone changes you'd get as an adult from mewing, good posture may be about 1 maybe 2 mm over years and years. Not significant at all. Get surgery and mewing for maintenance. That's what I'm doing anyway. No point in wasting years for a possible improvement.

 On that note though I've wondered if taking growth hormone and/or testosterone along with mewing could actually provide measurably better results? Anybody try that?
