Thank you for inviting me to answer this question. Unfortunately your question is not clear, what do you mean by supporting products. Did you mean promoting products ?

if it will be a pharmaceutical product, for sure you´ll more than those´s

Even I can write sentences in supporting products.

It depends where are you posting it. Sometimes can be perfect, sometimes can be to much or to less. So it depends where are you writing it (channel of communication, product type, features and so on).
