I'm using 100mcg of clen and 50mcg of T3. I don't shake that much but instead I have small musclecramps in the hands and feel as if I'm running a fever. I feel very "heavy" in the head and tired all the time. But when I train it all goes away
I take the T3 with my meals. Much less side I think
T3 can upregulate the number of adrenoreceptors and can therefore cause the shakes. This will be especially noticeable if you are taking stimulants such as ephedrine or clenbuterol.
