If you asking how much slin it will take to overcome t-3 catabolic effect, then its a question you will have to answer yourself.
I would say if you are taking 50mcg ED, you will need about 5-6ius. You must use glutamine and creatine with slin. Its a must!!
I nice WPI is needed during slins active time. Since WPI is the fastest to be digested it works awsome with slin to maximize anabolism created by protien and its amino acids
