RE: peep sight?
If you are using a string loop just turn the loop in the opposite direction the peep rotates when you draw it. Do this until it rotates into the correct spot. That is one of the advantages of using a loop.
If rotates a lot then you will have to press the bow and add or remove a half to one twist on the string.
Until you can get a chance to do that you can nock an arrow and then turn the string before hooking your release up. The nock should hold the string in place while you draw. Not something I would want to do when hunting though.
And if you have a new string shoot it a few hundred times before making any adjustments.
