Triiodothyronine, also known as T3, is a thyroid hormone. It
affects almost every physiological process in
the body, including growth and development, metabolism, body
temperature, and heart rate.
Production of T3 and its prohormone thyroxine (T4) is activated by
thyroid-stimulating hormone (TSH),
which is released from the pituitary gland. This pathway is
regulated via a closed-loop feedback
process: Elevated concentrations of T3, and T4 in the blood plasma
inhibit the production of TSH in the
pituitary gland. As concentrations of these hormones decrease, the
pituitary gland increases production
of TSH, and by these processes, a feedback control system is set up
to regulate the amount of thyroid
hormones that are in the bloodstream.
As the true hormone, the effects of T3 on target tissues are
roughly four times more potent than those
of T4.Of the thyroid hormone that is produced, just about 20% is
T3, whereas 80% is produced as T4.
Roughly 85% of the circulating T3 is later formed in the thyroid by
removal of the iodine atom from the
carbon atom number five of the outer ring of T4. In any case, the
concentration of T3 in the human blood
plasma is about one-fortieth that of T4. This is observed in fact
because of the short half-life
of T3, which is only 2.5 days.This compares with the half-life of
T4, which is about 6.5 days.
L-Triiodothyronine affects almost every physiological process in
the body, including growth and
development, metabolism, body temperature, and heart rate. T3
increases the basal metabolic rate and,
thus, increases the body's oxygen and energy consumption. The basal
metabolic rate is the minimal
caloric requirement needed to sustain life in a resting individual.
T3 acts on the majority of tissues within
the body, with a few exceptions including the spleen and testis. It
increases the production of the Na+/K+
-ATPase and, in general, increases the turnover of different
endogenous macromolecules by increasing
their synthesis and degradation.
Cytomel (T3) does speed fat loss. As a guideline, for most 12.5
mcg/day is a conservative "supplement" sort of dosing that seems to
have no detectable adverse effect on thyroid function at all. 25
mcg/day is a "supplement" sort of dosing that does have some
inhibitory effect. 50 mcg/day is a reasonably conservative bb'ing
sort of dose that, of course, is more inhibitory. 75 mcg/day is
getting into more of a problem area; 100 mcg/day in many cases
leads to loss of muscle size and strength.
These doses are in reference to legit T3 provided in tablets such
as Cytomel. Liquid formulations are usually unstable and as a
result, the above numbers in many cases won't match up to
experiences with liquid products, or for that matter, experience
with a liquid product at one time may not match up with experience
at a different time, due to the stability problem.
