Just started my E/C stack. Ran it last summer with decent results. Been reading a bit about T3 and thought it might be a good stack with E/C.
Wrong section, but I'd personally opt for no exogenous thyroid hormone. If you want something to naturally elevate levels,contains an olive leaf extract with very impressive t4/t3 turnover data
