T4 a fat burner ??

[Legolas]

t4 does convert to t3 - the thing is the body controls this conversion process...will exogenous t4 result in higher t3 levels = probably - but not to the extent or efficiency to make it a good stand alone fat burning choice.....

aha ok i get that but in case when T3 in large doses is ingested , the human will stop every conversion of T4 into T3 but some people cycle T3 and T4 together , will T4 when NOT converted into T3 burn any fat ??

My experience in working with others has been this-when t-3 is ingested in high doses, adding t-4 into the mix does nothing to further increase t-3. Therefore, treat a t-3/t-4 combo as if the t-4 is not present and go by the t-3 dosage only.
