How much priming sugar

I am going to make a belgian tripple for the first time.  I have read they tend to be very carbonated and I want to bottle condition for authenticity.  Should I stick with the 3/4 cup sugar to five Gallons?  I was thinking of adding a cup of sugar.  Will I run into problems with gushing or exploding bottles?

You could run into an explosive problem.  What i would recommend is a a thicker bottle designed to hold higher pressure.

I would just prime as normal.  Don’t use any extra.
