Unless you cut a couple strands your string will be fine. They are made to handle alot of pressure. If a bow string was that weak from some peep changing I don't think you could ever shoot it to begin with! I learned the hard way just before season, when I accidentally cut 3 strands on my string, and was told I'd have to replace it. Just be sure to keep it waxed up good, so it doesn't dry out, and to protect it from the elements.
