IGF-lr3 effecting TSH(thyroid stimulating hormone)

[Jookington]

I just had blood work done (attached below)and saw that my TSH came back under the not so good category according to the lab perimeters. I just started igf-lr3 the day before so was wondering if this is normal after injecting 20mcg bi laterally and or is this something to be concerned about. I also have been using t3 and clen two weeks before and might be the culprit. Since have discontinued t3 and clen.

Your TSH is low due to the t3 you were taking causing a negative feedback ie your body didn't need to make its own thyroid hormone because you were taking it exogenously.

Like Sgt said its from your t3 use bro....it will bounce back.

I was on T4 (converts to T3) for two years 100mcg/ed. When I get off, my natural TSH level was back within 4 weeks. You'll be back to normal in no time.

Was that for fat loss? The T4 im talking about.

Scotch I'd bet it was back in a matter of hours. Guessing you didn't test for 4 weeks? Yes, no?

Id agree. Given it was with t4.
