Your friends are lying. Perhaps they are talking about prop? I would not pin test susp any less than twice a day. Like said above though, I would actually recommend like three times a day..
You didn't realize it? Wtf man? Mistakes like this shouldn't really happen on AAS man.. No excuse.
I double, or even triple check EVERYTHING before pinning. All we need is for someone to die or get severely injured by "not realizing" something and bringing even more negative views towards AAS..
