you gotta try it out... dosing is diffucult though.
i run t3 year round. i love the fact that i can control my metabolism and switch between bulking and cutting whenever the fuck i want without having to slowly increase or decrease my calories (reverse diet). this saves a TON of time and hassle imo.
dont run any less than 50mcg, thats useless imo. 25mcg is a replacement dosage for most people. some on t3 therapy need more (even up to 75mcg or so). however to give you a picture, my last bloodwork was on 75mcg t3 daily and my t3 level was twice the upper reference range, so extremely hyperthyroid already.
you can run 50mcg upwards, no limit basically.
however above 100mcg t3 makes you insanely flat and weak... ive abused it quite a lot in the past up to 200mcg a day and 200mcg gives DNP-like results, however at that dosage its seems to COMPLETELY stop glycogen storage. makes you look like you dont even lift, however it all comes back when you cancel it..
also t3 increases protein turnover. that means it increases both nitrogen retention (=muscle gain) and breakdown (=muscle loss), however the higher you go the more this tips towards breakdown, so high dosages are very catabolic.
personally i consider 75-100mcg the sweet spot, it greatly increases fat loss and keeps metabolic rate up, it synthetically keeps your mteabolism kicking (whereas on low calories your metabolism would normally decrease more and more the lower your bodyfat drops).
75-100mcg also make you flat and are very detrimental towards strength, however i can still lift intense and heavy when i got stims in my blood.
on 100mcg upwards you can expect a strength drop of AT LEAST 30% within a week (due to glycogen and atp synthesis). its just temporary though.
