MegaMagnum is a male enhancement drug, and no scientific proof currently shows that it works. Some customers have noticed temporary improvement of quality and duration of erection, while others have said they saw no improvement at all, according to Consumer Health Digest.
The list of ingredients in MegaMagnum includes niacin, zinc and a blend of natural herbs. No information is available regarding how these ingredients work to improve male sexual enhancement. Niacin is known to improve the blood flow to the penis, and zinc increases the production of testosterone, which is connected to sexual drive. Consumer Health Digest states that even though these ingredients might improve sexual drive and erection, no current clinical studies support these claims.
