Ah, that makes sense. So this is rather a reverse relationship query. In that case your friend was correct, but it can be done in a single query:

<?php
$related_posts = get_posts(array(
  'post_type' 	  => 'post',
  'numposts'	  => -1,
  'post_status'	  => 'publish',
  'orderby'	  => 'title',
  'order'         => 'ASC',
  'meta_query' 	  => array(
    array(
      'key'     => 'related_products',
      'value'	=> '"' . get_the_ID() . '"',
      'compare' => 'LIKE'
    ),
  )
));
?>

<?php if ( $related_posts ): ?>
  <ul class="medium-block-grid-5 blog-posts">
    <?php foreach( $related_posts as $rp ): ?>
      <li class="post">
        <a href="<?php echo get_permalink( $rp->ID ); ?>" title="<?php the_title_attribute( array( 'post' => $rp->ID ) ); ?>" ><span class="featured-title"><h3><?php echo get_the_title( $rp->ID ); ?></h3></span></a>
        
        <?php if ( has_post_thumbnail( $rp->ID ) ) : ?>
	  <?php echo get_the_post_thumbnail( $rp->ID, 'regular-posts' ); ?>
	<?php else : ?>
	  <img src="<?php echo get_template_directory_uri(); ?>/img/no-image.png" alt="" />
	<?php endif; ?>
      </li>
    <?php endforeach; ?>
  </ul>
<?php endif; ?>
