>>12810435>>12810435I dont know, try it out.
I've been chewing 10 gums for 3-5h for 9 months now.
As quite expected, my masseters hypertrophied. I however didnt do any facial width measurements, so i dont know if my facial width changed although my face looks shorter. My jaws dont look like a fragile tmj machine anymore.
Look at Bratt Pitt, he used to have massive jaws, with big masseters, well he doesnt anymore.
