Koen, to answer your question, yes, 25mcg of Cytomel will supress thyroid function. Your thyroid levels have a baseline. If you introduce exogenous thyroid hormone into the body, the thyroid will supress its own production so that the baseline will be met. For instance, lets say that your body normally has 30mcg of T3 present at any given time (baseline). If you take a 25mcg Cytomel tab, the thyroid will supress its production to only 5mcg of T3. If you do not go past your body's baseline with your Cytomel (T3) dossage, you will not experience any effect outside of a normal metabolism. However, if you go above your baseline with exogenous thyroid hormone, your own thyroid will supress its production as it sees no need for it (the tyroid function has a feedback loop the same as androgen feedback loops in the hypothalamus). After you go above your baseline, you will start to reap benefits of exaggerated T3 levels. But make sure you are using AS while increasing T3 levels as T3 will eat your muscle due to its energy demands -catabolism.

You are one lucky SOB that I'm using WebTv right
now, and can't copy/paste because i would
put you to shame.
T3 is catabolic? Agreed. It DOES work through
PROTEOLYTIC pathways.
25mcgs T3/day Catabolic???? Maybe not.
Look at the studies in Medline done on patients
with T3, and look at the dose response curve
for T3/TSH.
It looks at the TSH levels for 25,50,75, and 100
mcgs of T3.
25mcgs of T3 only inhibited TSH to a very small
degree. 50,75, and 100 did not. They suppressed
it.
T3 increases the METABOLISM OF PROTEINS.
If T3(25mcgs/day)+steroids are taken per
day a synergistic effect occurs.
While steroids primarily decrease protein break-down
T3 increases protein turnover.
I'll agree that if you don't consume enough protein
T3 is CATABOLIC(at 25mcgs/day), but if you consume
1-2g protein/lb of bodyweight you will synthesize
MORE PROTEIN from your food, and the steroids
will decrease the amount of protein being
broken down by the T3.
The conundrum here is: The amount of protein synthesized
by the T3 has to be bigger than the amount of protein
broken down by the T3. Having said that, with the addition
of steroids, my hypothesis just happens to become
true because the steroids will seriously blunt
T3's catabolic effects WHILE NO AFFECTING
T3's PROTEIN TURNOVER ENHANCING
EFFECTS!!!!!!
Result: INCREASED MUSCLE GROWTH.
Stew, you have to THINK once in a while and
not just think everything is set in stone.
I thought you did research?
And FYI: Stop being such a hard-ass.
Godspeed
