I first pinned under the supervision of a buddys dad who was a doctor while playing football in 1991. I have always been supervised by a doc while cycling and will again. He is not a fan but he also understands his obligation to care for my other organs at the same time. Privacy in the medical field is a beautiful thing. I recommend doing the same thing if its the route you choose to go as I did. Over these 20 years I would cycle every 18 months sometimes shorter in between sometimes longer depending if I had plateaued or not. I am no contest guy just enjoy looking good and feeling healthy. I will say I am completely confused on who to order from. There is good and bad on all. Its not like I am ordering a computer from an online reseller though either. Anyhow just a little background thanks for all the knowledge as well.
