Thread: Thermal Stack

From another board, but I thought I'd see if there were any members here which might have something to offer.

Caffeine and ephedra do not affect the thyroid. The effect of this "pseudo-amphetamine" is an increase in cellular respiration. The individual cells throughout the body contain sodium/potassium pumps which are constantly working
to maintain the electrical activity of the entire body.
ECA merely speeds up the pump action of the cells which requires more energy from the cellular level. More energy
expenditure from the cells requires more calories to maintain. As a result fat is burned faster due to an
overall increase in resting metabolic rate. The thyroid is not directly affected.
You are referring to a hormone in the thyroid which controls body size named "triiodothyronine" or "T-3".
The output of T-3 is not involved in the use of ECA.

My reply:

Thanks again for the reply, I'm getting much closer to a complete answer. Hopefully my continual prodding won't sound ungrateful.

You mentioned that the thyroid is not directly affected, and that the output of T3 is not involved in the use of an ECA. I continually run across opposing information, which specifically mentions that ephedrine stimulates the thyroid gland to transform thyroxine into triiodothyronine, thus accelerating the metabolism. If this is the case, we are artificially stimulating T3.

My logic tells me that anytime you artificially stimulate a hormone, you set up the potential to deregulate that part of the body which normally provides this function (particularly the thyroid, but even possibly the pituitary gland and hypothalamus).

I'm probably nitpicking here, as long term use will probably induce a heart attack before hypothyroid or hyperthyroidism occurs, but the evidence seemed to present itself so I thought I'd spark a debate...
