Duplicated output with if statement

I'm doing a pizza menu on my home page using a custom loop for that, and I want to print the pizza size variations with the prices.

  <ul class="products">
            <?php
            $args = array(
              'post_type' => 'product',
              'posts_per_page' => -1,
              'product_cat' => 'pizza',
              );

              $my_loop = wc_get_products($args);
                foreach ($my_loop as $key => $product)
                {
                  echo '<li>';
                    echo '<h3>';
                      echo $product->get_title();
                    echo '</h3>';
                    echo '<div>';
                      echo apply_filters( 'woocommerce_description', $product->post->post_content);
                    echo '</div>';
                      if ($product->get_type() == "variable") {
                        foreach ($product->get_variation_attributes() as $variations)
                         echo '<pre>'; echo var_dump($variations); echo '</pre>';
                         {
                          foreach ($variations as $variation) {
                          echo '<p>';
                            if ( $variation = '32-cm') {
                              echo 'pizza 32 cm - ';
                              echo $min_regular_price = $product->get_variation_regular_price( 'min' );
                            }
                          echo '</p><p>';
                            if ( $variation = '45-cm') {
                              echo 'pizza 45 cm - ';
                              echo $max_regular_price = $product->get_variation_regular_price( 'max' );
                            }
                        echo '</p>';
                          }
                        }
                      }
                  echo '</li>';
                }
                ?>
          </ul><!-- .products-->

So my problem with this code is that I'm getting the results twice for every product:

pizza 32 cm - 27.00

pizza 45 cm - 46.00

pizza 32 cm - 27.00

pizza 45 cm - 46.00

can you please point me out on my mistakes with this code?
