Calling product category

For some reason calling the product category in a loop is eluding me. I tried every function I could find and its not working. check this out:

<?php
			  if ( in_category('permanent control' )) {
			  			echo mp_list_products();
			  }else {
						echo mp_product_price();
			  			}
						  ?>

The returns are there simply for testing. Like I said the category doesn't work. The thing is when I setup up php to print a category list it doesnt include my product categories, only the post categories. I feel like there is something im missing. Anyone have any ideas?
