I am 27 years old. I have smaller penis 3 . I went to dr.kamaraj sexologist in chennai. He took all teSt and gave me nano leo and jackjoy along with why no 12 inches cream. Am using this for past four months but no changes in size of my penis. My testosterone level is 7.48. Is it worth taking this pills and cream? Please suggest me.
