You may want to be careful where and when you drink Stiff Bull Herbal Coffee. The Food and Drug Administration (FDA) has issued the following warning:

The Food and Drug Administration (FDA) is advising consumers not to purchase or use Stiff Bull Herbal Coffee, a product promoted for improving energy. This product was identified by FDA during an examination of international mail shipments.

The FDA has found desmethyl carbodenafil in the coffee, an ingredient quite similar to sildenafil, the active ingredient in Viagra. Viagra, as you probably know, is not coffee but a medication originally approved for erectile dysfunction. (Although, nowadays many people may use Viagra and similar medications as sex aids.) Talk about using coffee to get up in the morning.
