 Provided you take proper precautions, taper your dose, and otherwise don't abuse it, it can be a very effective and relatively safe substance. The great majority if not the only research out there pertaining to thyroid levels post T3, T4, Triac, etc. cycles shows that even if you quit cold turkey, your thyroid will bounce back within ~3 weeks. Of course, doing so would be stupid as the metabolic slowdown that could occur would most likely negate any progress in fat loss that you made, but the "you could damage your thyroid forever" is mostly hearsay/gym lore.

Yeah, even at your age. The only issue with age with most of these things, despite what you read on forums and hear in the gym, is that younger people seem to be more irresponsible on average than older ones. Of course this isn't always the case, but I think it's safe to say that there are more stupid and irresponsible people under 21 than there are over, even though there is an overabundance in each age range  With that said, if you could stick to a reasonable dose, don't have the "if 2 is good, 4 is better" mentality, and take proper precautions, any problems that could arise wouldn't be due to your age.

what possible procautions should i take and why was the syntrax version pulled of the shelves a few years ago? [MLINK=120]Scivation[/MLINK]'s Marc = Crazy Routines.

You're right, that was my mistake; I'm not sure what I was thinking with that. Maybe something like a 3 week taper was on my mind? Anyway, for anyone who looked at that part of my post: look at powergrudge's. Precautions you could take would be running something like forskolin or 7-keto-DHEA/7-OXO with it or post cycle (or both) to keep your thyroid running as well as possible as well as to help with output after the cycle. Others would be to obviously ramp down slowly and do things you would normally do with elevated metabolism: staying well-hydrated, for instance. I'm not sure of the legalities of Syntrax's product being pulled. I don't know if it was in the same class of drugs as it is now or what. Possible thyroid suppression as you are aware could have been an issue as well (customers not being aware of this in a commercially available product).

Re: Thyroid suppression
| QUOTE | Like the hypothalamic-pituitary-gonadal axis, the thyroid gland is under negative feedback control. When T3 levels go up, TSH secretion is suppressed. This is the mechanism whereby exogenous thyroid hormone suppresses natural thyroid hormone production. There is a difference though between the way anabolic steroids suppress natural testosterone production and the way T3 suppresses the thyroid. With steroids, the longer and heavier the cycle is, the longer your natural testosterone is suppressed. This is not the case with exogenous thyroid hormone.
An early study that looked at thyroid function and recovery under the influence of exogenous thyroid hormone was undertaken by Greer (2). He looked at patients who were misdiagnosed as being hypothyroid and put on thyroid hormone replacement for as long as 30 years. When the medication was withdrawn, their thyroids quickly returned to normal.
Here is a remark about Greer's classic paper from a later author:
"In 1951, Greer reported the pattern of recovery of thyroid function after stopping suppressive treatment with thyroid hormone in euthyroid [normal] subjects based on sequential measurements of their thyroidal uptake of radioiodine. He observed that after withdrawal of exogenous thyroid therapy, thyroid function, in terms of radioiodine uptake, returned to normal in most subjects within two weeks. He further observed that thyroid function returned as rapidly in those subjects whose glands had been depressed by several years of thyroid medication as it did in those whose gland had been depressed for only a few days" (3)
These results have been subsequently verified in several studies.(3)(4) So contrary to what has been stated in the bodybuilding literature, there is no evidence that long term thyroid supplementation will somehow damage your thyroid gland. Nevertheless, most bodybuilders will choose to cycle their T3 (or T4 which in most cases works just as well) as part of a cutting strategy, since T3 is catabolic with respect to muscle just as it is with fat. As previously mentioned, long term T3 induced hyperthyroidism is also catabolic to bone as well as muscle. |

interesting, thank you very much. A question though, is T4 or even T5 (from Dorian Yates, which looks very interesting please tell if anyone has used it before.) less catabolic with equal fatloss results as T3. [MLINK=120]Scivation[/MLINK]'s Marc = Crazy Routines.

T3 (not the product that comes up when you link the name T3 here), actual synthetic T3 thyroid hormone (also known as cytomel) is the most effective. It is basically like taking testosterone, but for the thyroid. Trimax (tiratricol/triac) is next; it is a readily metabolized molecule that is turned into T3. The jury is out on which is worse (ie suppressive/muscle wasting) for you, triac or actual t3. I dont think T4 has much merit for fat loss, at least not as much as t3.
