vigrx plus reviews

To test the effectiveness of the VigRX Plus claim for longer and harder erections, a closely- supervised study was conducted among 60 males in their 20s and late 40s, and were properly screened to rule out disorders that may be affected by the supplement intake. The study period was for three months, and the dosage was individually-designed according to the test subject’s need and physical condition. The progress was recorded through frequent visits and survey questionnaires given to each participant to track their own perceived changes.
