Basically I started off right at 7.25 inches BP and due to budget reasons I bought a super cheap extender off of an app. Almost right away I grew. Only a couple of months and I reached right above 8 inches. I kind of got obsessed with the feeling, but I've completely stopped growing. Is close to an inch the max for most people? or could I reasonably grow more if I throw money at an expensive extender? Money is a bit tight so I don't want to throw money unless I can reasonably get results, but I REALLY want to hit 9". Thank you!
