Generic Tirosint - Levothyroxine Sodium capsules USP made by Lannett - has anyone in the UK managed to obtain this medicine?

[origami]

I would like to try Tirosint - to combine it with a trial of Liothyronine - I believe Tirosint is available from Roseway Labs on private prescription. But it's very expensive. I had heard that there was a generic version made in the US by Lannett Company Inc.

Does anyone have any information about this product? I would like to know if it has the same formula as Tirosint - with the same inactive ingredients and if it is cheaper than Tirosint and if it's available on prescription in the UK?
