Apollon Nutrition Casanova Casanova by Apollon Nutrition is a natural solution for men seeking to reclaim their “getting it on” energy, vitality and staying power. Ok we will say it….Casanova is a natural solution for those looking into sexual enhancement supplements. The ingredients found here in Casanova are designed to increase blood flow (needed for erections btw), enhance your mood, and get you to perform your best. Now the serving size might throw you off, its 8 capsules….but for good reason. This product is loaded with nitric oxide boosters that aid in “getting it up”, but these same ingredients can also be great pre-workout.
