Grade: F (Severe Risk)

Extra is a natural male enhancement product that guarantees an increase of 3 inches in length and 20% in width in penis size.
We were suspicious of the results guaranteed by Extra yet interested in testing this product for ourselves. Could a product really increase penis size by 3 inches?
The claims made by Extra sound too good to be true. Nonetheless, we had to investigate this incredible claim regardless of our reservations.


Extra is advertised as a natural male enhancement product proven to increase penis size and circumference. The ingredients used in Extra are Pomegranate, Niacin, L-Arginine, Cordyceps and Zinc. Our laboratory tests found only slight traces of L-Arginine in Extra’s formula. L-Arginine is an amino acid that affects the Nitric Acid levels in your body. Increased levels of Nitric Acid trigger a reaction that causes the blood vessels to dilate; improved blood flow increases the potential for harder erections. However, L-Arginine only increases Nitric Acid levels if taken in high doses. Pomegranate and Niacin are both safe and tested ingredients yet ineffective ingredients for increasing penis size. Clinical studies suggest that both Pomegranate and Niacin are effective supplement for increasing your energy levels. No correlation exists between increased energy levels and permanent penis growth.

Bottom Line

We would never recommend the use of this product. No scientific evidence exists to suggest Extra is capable of increasing penis size. We strongly encourage readers to continue researching the safest and most effective male enhancement product available for their condition.
