well both T4 and T3 are active and used in metabolism but T3 is 4-5x more potent than T4. Also only a small percent of T4 is converted to the more active T3 so I dont rly understand why people take T4 at all for fat loss. Just find T3 and use that.
The ip t3-4 combo is the only thing from them that I did not get much from. straight t3 worked way better. The t3 dose in those were only something like 17.6 mgs. I guess if I took like 5-6 of those they may have worked better for me but nah i'd just go with t3 if it were me. T
