Unless you are going to use gear, I would advise to not use T3. Prov has no muscle building properties so it will not give you the effect you are looking for. As for keto, you can do just fine without using it on a clen cycle. Adding it in isn't going to hurt, but by slowing increasing the clen dose, it will continue working over the length of your cycle. If you do want to use keto, start with 1mg in wk 5 or 6. See how that works for you.
