Programmatically load the contents of a Product in a particular product type
This can be done with an EntityFieldQuery:

&lt;?php
  $query = new EntityFieldQuery();
  $result = $query-&gt;entityCondition('entity_type', 'node')
    -&gt;entityCondition('bundle', 'product')
    -&gt;execute();
  $nodes = node_load_multiple(array_keys($result['node']));
