This is a highly speculative claim and based off of a single sheep study.
I normally do not recommend running exogenous thyroid for as short as six week bursts simply due to the time it takes for the hormone to suppress and reach stable levels in the system. Conversely, once suppressed, the thyroidal axis may take anywhere from 2-6 weeks to restore endogenous production so this is a lot of stress on the body for only six weeks of usage.
There is a synergy with albuterol, due to it being a beta two agonist, however albuterol is VERY weak and I'd urge folks to use clenbuterol if looking for a beta two agonist to run alongside T3.
