@soarus57 I started using Restorex in March of last year. The goal is daily for at least a half hour. I might have averaged 4-5 times per week 30-45 min. Gained about a half inch to inch in length and perhaps a 5 degree lessening of the bend to the left. Seems as though it improves circulation or at least the ability to get and maintain an erection but hard to tell since I use daily tadalafil for enlarged prostate and generic Viagra for weekly intercourse.
