Thanks for the reply.
I take the Utrogest. oil (excipient) information from a Google search: Pharmaceutical Journal and Medicines Online - seems it changed around March/April 2015. BUT please check. I phoned Besins (the manufacturer) and they couldn't tell me!!

I would most definitely insist that the GP/pharmacy/dispensary double-checked the packs obtained as I suspect that there's still some older stock out there.
I'm not sure whether I want to use cyclical or continuous HRT at the moment, nor which is safest and best and most suitable for me (and my GP certainly doesn't know). I came off the pill nearly 2 years ago, just pre 50, and don't therefore know where I am or what's happening, cycle wise.
I had some spotting, discharge or mild bleeding last year (i.e. first year off pill and on HRT) , but that was a response to the progesterone only pill and since stopping that there's not really been a withdrawal bleed after taking 14 days of MPA each month (which there's meant to be) nor after a few months of not taking either that or the Oestrogel. I understand that a small % of women do react like this, and perhaps as I was on a fairly low Oestrogel dose it wasn't utterly unexpected.
I did go through the scan and internal investigations route last year because of the not-utterly-predictable-cycle issue (what a joyous experience

) and all was OK bar a small polyp and fibroid, duly removed. No mention's ever been made of ongoing scans unless there is a 'suspicious' bleed situation again.
I think I've decided that I want to go back onto HRT after a test break without it, and I want to stay on the transdermal oestrogen (Oestrogel) as it seems to suit me and is 'safest' on many counts. I'm happy to stay on the MPA, either cyclical or continual, as it seems to suit me well enough: but I just wonder if the Utrogest. would be worth the trial/swap on 'safety' grounds given the bio-identical issue. It would be the oral route for me.
Not even sure if it's worth swapping, but I think that I'd be happiest knowing that I'd done what I can (on current thinking) to minimise HRT risks - I'm just interested, if available, in some feedback on whether others would stick with the known devil or take the chance with someting which might or might not cause several months of 'hassles'. Had a year of them already, between the hysteroscopy/polypectomy, Mirena coil and other new, ongoing, persistent health downers which might or might not be menopause related.
Cheers.
