add over rides for the VM product displays  to your template

components\com_virtuemart\views\productdetails\tmpl\default.php
over ridden in
templates/YOUR_TEMPLATE/html/com_virtuemart/productdetails/default.php

add the  echo 'ISBN: '.$this->product->product_gtin;

components\com_virtuemart\sublayouts\products.php
over ridden in
templates/YOUR_TEMPLATE/html/com_virtuemart/sublayouts\products.php

add  echo 'ISBN: '.$product->product_gtin;
