Am I ruining my dabs doing this?

So one of my employees saw me filling up my pucks and he told me I am ruining my dabs by doing this. Basically what I do is I buy an OZ of wax then I put my little glass pucks on a heat mat. The heat mat melts the dabs so I can stuff as much as possible into the puck. My buddy is telling me by preheating the dabs I am essentially “activating” them early. That can’t be true though since they’re not vaporizing, right? He told me it’s the same as putting weed in the oven to turn them into edibles. I still get plenty high off of them. Am I making my dabs less effective by doing this?
