Placebo t3

[Mousemole]

I wonder if anyone can help. My first packet of T3 was via a contact in the uk. I felt great supplementing my t4 with 25mcg of t3 morning and night. It was made by unipharma.

It was very expensive so i sourced some from Greece - also made by unipharma.

I am worried that the Greek ones are placebos as I just don't feel the benefits that I did before. They are also unipharma and look the same as the first pack I had from the U.K. but I just don't feel the same. Any thoughts ? Thank you.
