Sikander-e-Azam plus penis supplements claim to naturally enlarge penis size without side effects through permanent penis growth of 1-2 inches in 2 months. The herbal supplement is said to provide thicker, longer and more defined erections as well as greater boosts in sexual confidence and energy. It works by containing aphrodisiacs that stimulate cell growth in the penis, allowing more blood flow for an increased size and more intense erections.
