Draggin',
Annie is right, everyone is affected differently. I started at 5mg in September, for a few days I was a little weak, but after around a week I could tell a difference in strength. I was really bad off when he prescribed it, he asked me at the appointment after all the strength tests how I got into his office.

Since then he upped me 5mg every week to my current 20mg dose. After every dose increase I could tell difference. I hope your 12 days on it work well for you, and hope you become stronger, and stronger each day.
Warm Regards!
