Anybody having trouble with this besides me?

I never have. how tight are they on the string? might have got a bad batch

what color are the nocks? I had some white ones that were a little weak, I replaced them with flo green nocks

A bunch of people were having this issue, including myself.  I phoned Gold Tip and they informed me they had a material issue but had fixed the problem. They asked how many arrows I had and I told them two doz. I received three doz nocks in the mail a week later and haven't had one break since, and I've been stumping with them to make sure.

Review old threads for much info

I had a batch of white nocks break. Switch to a different color like someone else said and problem solve.

I just recived 4 doz from goldtip yesterday they were helpful an glady replaced 4 dozen nocks for free.just give them a call
.

Yup- do a search.  A bunch of us had them breaking- different colors too.  I went to Signature nocks.  I realize that GT replaces them- which is great service. . .BUT honestly I am not sure they would stand behind a damaged bow and I had two dry fires!    

I also ruined a bow, but I'm not sure if it was a bad GT nock, or one that I filed out to fit the serving so I don't think I have an right to complain. Sure quit that practice, though!

Yeah, do a search and you'll find the info.  I contacted GoldTip about it and they sent out new nocks, free of charge right away.  Great customer service and I haven't had any nock issues since.

I have had a bunch break. I sent several emails and no response.

Can you post or PM the phone number ?

I never had the problem.

just go to goldtip.com or googel them

I called the main number on their website and got to someone right away.  He said it was a known issue that was corrected and offered replacements.  I already replaced about all of mine and seems like a hassle for a someone to take the time to send a couple dozen nocks, so I turned down the replacements, but it was handled well.  I just wanted to know if there was a color to avoid.

The ones I have were the green.Ruined a bow yesterday.
