I do understand the principle of t-4 converting to t-3 in the body, but why would u choose to take t-4 over t-3 when u could just skip the body's natural process and substitute in t-3. Or is it because while your on GH your trying to keep your body's natural production of thyroid hormone at normal levels since GH suppresses the Thyroid?? Any information would be helpful.
Thanx,
