I didnt get my blood tested before I did any T3 but I did a cycle of a total of about 7 weeks with 1 weeks amping up and 1 week amping down. The highest I ran it was 120mcg per day. I got blood work done 3 weeks after the use of the T3 and 4 weeks after the use of 50mg of winny ed for 4 weeks to see if my test had recovered. MY test was still low at about 180 with normal range i think at 270 to 700. But T4 was already at .667 with normal range being .7 to 1.7. So I am close to being fully recovered aftert the T3 use only after 34 weeks
