Lone Az,
I beleive that you have very good points. This stuff is for veterans only, and pre contest.
However, it does not shut down your natural thyroid production permanently. That's a myth.
It does seem like a stupid drug to take however since it takes so much commitment post cycle. You think a post cycle crash on AS is bad? Thyroid crash is much worse. You will be shut down and below normal for at least 4weeks after your cycle, and up to 6 weeks (for regular cycles).
This is a time to start cutting back calories and dieting, if you stick to your buffets and pizza you are quite "FUCKED".
I'll be posting a HUGE write up on T3 in the near future. Stay tuned.
In the meantime, here's a study I found posted by Brock Stasser.
N Engl J Med 1975 Oct 2;293(14):681-4
Recovery of pituitary thyrotropic function after withdrawal of prolonged thyroid-suppression therapy.
Vagenakis AG, Braverman LE, Azizi F, Portinay GI, Ingbar SH.
The pattern of thyrotropin secretion was analyzed in seven euthyroid women, before and after withdrawal of long-term thyroid hormone, by serial measurements of thyroid 131l uptake, serum thyroxine, tri-iodothyronine, and thyrotropin concentrations, and the response to thyrotropin-releasing hormone. During exogenous hormone administration, 131l uptake was suppressed, and serum thyrotropin concentrations before and after administration of thyrotropin-releasing hormone were undetectable.
After withdrawal of exogenous hormone, thyrotropin secretory function was transiently impaired, as indicated by undetectable basal thyrotropin concentrations together with absence of response to thyrotropin-releasing hormone, and subsequently by normal values of basal thyrotropin concentration and normal responses to releasing hormone while serum thyroxine and tri-iodothyronine concentrations were subnormal.
Decreased thyrotropin reserve persisted for two to five weeks. Detectable values of serum thyrotropin (less than 1.2 muU per milliliter) and a normal 131l uptake usually occurred concurrently in two to three weeks. Serum thyroxine concentration returned to normal at least four weeks after hormone withdrawal.
