Has anyone gone on a flight to Turkey, bought a backpack full of Avodart (say 12 months supply) and come back without Airport Security being a pain in the ass?

I live in the UK and I am thinking of going to Turkey heading straight to a pharmacy buying like 360 Avodart capsules (its like £4 a box in Turkey compared to £25 here). And come back on a same day return flight

I know the pharmacies dont care and will sell it without prescription but will airport security be ok with it? I know you're only meant to have up to 3 months supply but its not exactly cocaine is it?

Has anyone done this?
