Question is if taking say 12.5mcg a day really is consequence free so to speak, not affecting your own output. My friend may do it for months after a show as he feels it helps him. He asks what I think but I have no answer, especially with no blood work.
Regarding catabolism, I've posted that one study many times that was fascinating to me. Went something like this:
- 50mcg T3
- Bed rest, slight downward tilt of the head
- with or without 200mg of test
Forget the duration but with the test there was no muscle loss, actually showed a slight increase in lbm (water maybe?) but strength went down (naturally).
I have very little own experience with it, tried it for a few days at a time for mood. Seemed to cause some insomnia acutely at 20mcg. I have been interested in possible acute performance enhancement, perhaps neural and perhaps increased accessing of bodily energy stores whether fat or other substrate. It has been reportedly used as a PED and I think the reasoning is the above. It's not banned by WADA. I further think it might work even better with some synthetic cortisone. For which athletes try to get a "therapeutic use exemption," for example for cortisone cream for "saddle sores" or whatever. Add a therapeutic use exemption for a beta agonist for exercise- or cold induced asthma lol.
