^^Yes, I believe he meant orally. Injecting such a compound is not needed.
I can offer that these are NOT U.S. pharmaceutical.
Thyrolar (Liotrix) is the only t3/t4 combination I am aware of, and it looks entirely different. It also does not appear to be Armour, Cytomel, Thyroxine, or similar products made in the U.S.
That being said, it could be an over-seas brand, but likely not Europe, Canada, the UK, Australia, or any developed nation with tight drug controls, as there are no imprints on the pills indicating the drug contained.
I cannot offer what are in these pills, but can only urge using caution if taking them.
