I just did my 2nd shot of sust 250. As weird as it sounds I think that it is agreeing with my body incredibly well. After only 1 week I feel more strenght in my bench and shoulder press's. I am going to run cytomel with the sust starting sunday. I am curious on how much I should take at one time and how often because I am worried about getting the thyroid problem if you take it wrong. Can anyone tell me how much to start with and how long to go for? thanks. PS i have 100 tabs of 25's
