Thankyou ladies, so it would seem that the Evorel 25 is the lowest one gets, delivering 25mcg every 24 hours, which appears to be a lot lower than what I am currently using which is 1 pump, which delivers 750mcg. I guess I could try half a pump, just very difficult to get the dosage correct with the pump action.
Trying to find the lowest dosage that is safe for long term use as I do not intend to throw away my HRT when I turn 60
