How to organize the output of text in Joomla under the product?

Question

PHP

Comrades! Help me please! The site has Virtuemart and K2 components. How can I display text under them on the product page, the difficulty is that under each product there should be a different text and it should not be in the description of the product, but under it. Through the module it does not work, because I can not find in the administrative page where to insert this module. On the screen, I marked the place where the text should be placed. Thank you in advance!
