Some over the counter, novelty boner pills, marketed as “all natural” sexual enhancements for men, have actually been found to contain traces of sildenafil, the stiff ingredient commonly found in the erectile dysfunction drug Viagra.

According to a recent analysis by the Federal Drug Administration, hard-on supplement Sexy Monkey tested positive for prescription erection drugs. Other products distributed by the company, which operates under the name Midwest Wholesale, are Boost Ultra, XZone Gold, Triple MiracleZen Platinum, Magic for Men, "New" Extenze, and New XZen Platinum.

The company has since agreed to recall certain shipments of the supplement. However, according to a press release issued by the company’s owner, his business only acts as a distributor and does not manufacture the pills.

So, if you recently noticed your convenience store stiffy pills working better than they ever have in the past, it could mean you have been ingesting small doses of prescription erection medicine. For some, there is no health risk, but for others with high blood pressure and heart disease, this pulsing detail could have some limp results.

So far, Sexy Monkey is the only product being recalled.
