Normal TSH, low FT4/FT3

[MyRevolution]

I'm on HRT 200mg/week.

I'm dieting and did a short 2 week cycle of Clen 100mcg/day, a T4/T3 combo of 50mcg/12.5mcg + T3 25mcg/day. Came off it and had blood drawn 6 days later.

My results (european units and ref ranges):

TSH 1.4 (0.2-4.0)
FT3 2.3 (2.5-5.7 low)
FT4 7.6 (9.0-22.0 low)

About 6 months ago, my FT3 was also in the low range, but my FT4 was middle of the normal range and TSH about 2 - I was doing a ketogenic diet back then...

Am I still rebounding from the 2 weeks of T4/T3 use, or is there reason for concern (secondary hypopituitarism)?

IIRC, thyroid meds can stay in your system 2+ weeks, so at 6 days you could easily be "under the influence". I'd talk to doc about retest later on.
