ΚΟΡΤΙΚΟΤΡΟΦΙΝΗ (ACTH)

Cialis contains tadalafil, which is medically known as a PDE5 inhibitor. Tadalafil works by blocking the PDE5 enzyme, which is involved in regulating blood flow to the penis during erection. Sexual stimulation is required before the drug works - without the stimulation it will have no effect. Cialis strengthens and supports performance and sexual relationships.
