Hello,

Use this ( paste in top of product-form.liquid )

{% assign has_z = 0 %}
{% for collection in product.collections %}
  {% if collection.handle == 'your-collection-handle' %}
      {% assign has_z = has_z | plus: 1 %}
  {% endif %}
{% endfor %}

 Note: Change 'your-collection-handle'  to actual you collection handle

now wrap your text in this condition

{% if has_z >= 1 %}
// Your text will go here
{% endif %}

Thanks

If you want to use it with multiple collection then use logical 'or' operator. 
Here you can check more about logical operator.
