If you are tilting your head to meet the peep move the peep. You should not have to adjust your form to look thru the peep sight.

This is how I anchor. Tip of the nose to the string, the string bisects the corner of the my mouth, hand under my ear or in the back of my jaw (depends on how my bow is set up) and the fletching of the arrow are between my chin and bottom lip. I do not use a peep any more.

If you are having trouble getting your peep location correct are getting your nose to touch the string then you may have to move your anchor point up some where your hand touches your face. Or your bow might have too short of ATA for your draw length. But if you are touching the string to the side of your nose this should be the case. You may even be a bit long on draw length.
