i bought some wild yam root because it was on sale and it was considered by some to be a steroid. it was cheap so i said i will try it. I took the root for a week or so and went up to exercise on the bike. I was surprised i set a new record. the next time (two days) a new record. i have been riding the bike for 14 years, now everytime i ride it it is close to the record and it has become real easy to maintain that time. The other exercises are also easier and i have noticed that my chest, shoulders and forearms are getting bigger. Everyone laughs about the wild yam root. Not I. jmn
