Take Doctor - Prescribed Medicine for Safety and Efficacy.

Buying "Cialis" (tadalafil) without a prescription (sin receta in Spanish) is illegal and dangerous in most countries.

1. Legal and safety reasons

- Prescription medications like Cialis are regulated because they can have significant effects on the body. Improper use without medical supervision can lead to serious health risks, such as interactions with other medications, underlying health conditions being exacerbated, and potential side effects that may not be properly managed.

- In the case of Cialis, it is used to treat erectile dysfunction and benign prostatic hyperplasia. A doctor needs to assess a patient's medical history, current medications, and overall health status to determine if it is safe and appropriate for them to use.

- Unregulated sources from which one might attempt to obtain Cialis without a prescription may also provide counterfeit or substandard products, which can be completely ineffective or even harmful.
