and your doing a cycle of aas... this will help you lose weight.. he is to young for aas so you go lose 13.45lb of pure fat natty in 45 days and log it!!!
now to the thyroid. the t3 cycle is just like a test cycle it shuts down normal function of the body nbut reganes it back... the parathyroid glands that are in most ppl located in the thyroid are the essential part of the gland itself... so with t3 just being a hormone seduce the hormone and not gonna avoid the fact of damage but the gland itsself will revert back to it's nomral function faster because of homeostatic mechanisms in the body. ie*
http://en.wikipedia.org/wiki/Thyroid you dont need test to live you need metabolism to live.... hope that explains it well enough.. if not the link goes to it being you may or may nnot be a med student you know the body wil maintain itself under harsh conditions and adjust.. sijmply put thyroid is important very important so the body will get it functioning faster for homeostasis..exit the grammer all typing is done on my phone some driving lol
