At what dosage does T3 become noticably catabolic, in general? I know that you can offset it with an anabolic (ph/ps) but what can you use now that is legal to help offset it? I don't want to use any ph/ps's so maybe a natural test supp. like Anabolic Matrix? I am going to do a clen/t3 cycle but I don't want to lose to much LBM yet I want my dosage of T3 high enough to still work. I have used clen in the past by itself for 2 weeks at a time, is it worth getting the keto to go along with it so I can run it longer, like 3-4 weeks at a time. thanks
