Do they work? Im currently 8 inches wanna get to about 11/12 max I dont want to go for surgery so is there anyway my penis will grow if i take pills or do penis enlargement exercises that involves a lot of pulling and stretching?
No. If they did, they would be prescribed by doctors not available over the internet.
Quite what you'd do with 12 inches that you couldn't do with 8 is rather question begging. You're already well-above average and any additional size would be more for ego rather than any practical benefit.
