OMG. What happened here? Just like every other motherfucking thing in this world anabolics and ancillaries follow a trend.
"You can use T3 and not fuck your thyroid if used right" and "You will fuck yourself up good " comments here (although they are common) are getting old. Dial dick, Humanoid I'm calling you out.
Where the fuck did you come to your conclusions? Personal research? Or, more likely, let me guess- you read some goofyass steroid profile about T3 that was published God knows how many years ago (I read that profile about 3-4 years ago) that said using thyroid hormones will fuck you up for life.
Heres a hot tip you guys who don't know- NOONE FUCKIN KNOWS!!! Anyone who has done any research or knows someone who has done research into the use of T3 or T4 in HEALTHY individuals please let me know, I might be out of the loop with this shit. May it shut down your T3 conversion? Yes, possibly. Of course this is different for everyone. I've run 2 extremely different T3 cycles and haven't had a problem with TSH levels so far. Does that mean it's safe for everyone- NO.
Yes Skinny, Synthroid is T4. T4 is converted to T3 in the liver. It is not nearly as "potent" as T3. T3 is the more active of the 2.
Did you fuck up your thyroid? I have know idea. My suggestion to you would be to go to a doc, get your thyroid levels checked after 2-3 weeks off cycle. Keep this in mind. You were using T4, which is different from T3. I wouldn't worry too much about it. Just eat like a horse and cardio like a bitch for a good 4-6 weeks- it might bring your levels back up.
I'm by no means a doctor (maybe someday) but I can't see your thyroid not coming back from depression.
