i would think the supression of t3 levels while on DNP would be muscle sparing. DNP will mostly burn just fat. Taking t3 could speed up fat loss, but muslce loss as well..
I really dont think you need to use T3 while on dnp. It would not make all that much a dif since the dnp will burn so much fat.... Not worth adding it if you ask me.
i just realized i am retarded and did not read this thread correctly.......
I would say it would be impossible to notice t3 supression while on dnp. T3 should start to shoot up after you stop taking it and you carb up. it will give you a nice anabolic rebound. I would not worry about it.
