| Well T3 is about about 4 or 5 times stronger than T4 mcg for mcg but you just as well just take a smaller amount of T3.. The risks to your thyroid are the same (when you adjust the dosage for strength obvoiusly)..
As John said dont even consider thyroid meds unless you have tried ECA and Clen... Also thyroid meds are catabolic so you would need to run with AAS to avoid muscle loss. |
