The U.S. Food and Drug Administration is warning consumers not to drink Longjack Coffee, in addition to other instant coffee products that have been recalled recently - Kopi Jantan Tradisional Natural Herbs Coffee, CaverFlo Coffee, and AMPT Coffee. These products are made in Malaysia, and promoted and sold online for sexual enhancement.
These products are labeled to contain instant coffee, non-dairy creamer, and other ingredients. However, FDA laboratory analysis confirmed:
CaverFlo Coffee and AMPT Coffee contain undeclared sildenafil and tadalafil;
Longjack Coffee and Kopi Jantan Tradisional Natural Herbs Coffee contain undeclared desmethyl carbodenafil, an analogue of sildenafil; and
All of these products contain undeclared milk. Source 8x.
