thyroid, T3

[skinnyfat]

If one does a cycle of T3, does their thyroid deregulate? I was wondering about people's personal experiences. Does it go back to normal, and how long does it take?

I did a 35 day pyramid peaking at 100mcg day and I did not notice any downregulation at all.

I am sure downregulation occured while on, but due to external intake it was not an issue. Upon discontinuance of T3 I was not lethargic or gain any weight so I would say I bounded back rather quick.

Yes, your natural thyroid production will decrease through negative feedback when you tack exogenous thyroid meds including T3. Whether your thyroid will come back to normal will depend on your particular situation- genetics etc. Most people will probably bounce back just fine. In terms of how long it will take to get back to normal, I'm not sure on this one. I would assume 8 weeks would be long enough to be sure your levels were coming back to normal but I think this will vary quite alot just like it does for testosterone levels in different people.

Hey, Zyglamail, how did the 35 day cycle of T3 work out for you? Any muscle loss?

Thanks.

 

[Zyglamail]

I would only use T3 on cycle and I was on cycle so no muscle loss. I added 14lbs in 4 weeks to my starting bodyweight and lost 3%BF at the same time.

i am with Zyglamail on this. I did a similar pyramid (max 100mcg) while on a cycle and lost 2% BF. Did not gain any afterwards so would say that all was ok.
I think it does depend on your own genetics but have not seen a medical study on it but sure one exists.

Good Luck

it is not the smartest thing to take thyroid meds that you don't need
