I love me some T3...Yummy. I notice a tremendous difference in bodyfat loss when I am in single digit bf%'s. It helps me get from 7-8% down to 5'ish% percent easier.
It's been awhile since i've been that low though. I only use T3 with AAS....the best is to use it with Trenbolone.
As to inhibiting the T3/T4 levels....
The conversion of T4 to T3 will be lowered while following a hypocaloric diet. This is via the 5'-deiodinase enzyme, which becomes downregulated. The amount it is downregulated, as well as how soon, will vary individual. The only way to really be sure on this is to have a Thyroid panel test completed (TSH, etc). However, because I feel that the side-effects of this drug are often exaggerated, you can just add it in while dieting when you reach a sticking point. Taking morning temp can be used, but will not always be accurate. I'll use it this way for myself though. Because I feel it is fairly safe, I do not get all anal on it. I probably wouldn't add it in until somebody is in single bodyfat digits (10% and below). Some others may need it sooner (before reaching 10-12% and below), but i'd get blood work done if you cannot get this low first as it may be another factor limiting fat loss....or better yet a bad diet and training.
Gonna throw T3 back in this summer with my first run of GH.
