Tamoxifen GEL form

Hi, is it true that Tamoxifen is only available in gel form in Australia and America? The reason I ask is. I saw an article in a UK newspaper from a few years ago online mentioning that Tamoxifen in gel works effectively and is useful for people with liver issues like myself my liver ALT has raised and I would prefer to be on the gel. How can I make this possible, please?

Also Is it possible to get drug absorption tests for tamoxifen privately anywhere ? Nhs don't do them ...

With liver alt raised it's hard to know what I'm absorbing or not to decide to continue or not. Thanks
