Travelling abroad with peps/hgh without a prescription?

I am from England and planning to go to Italy soon to visit family. I was wondering if anyone knows or has had experience with travelling abroad with peptides/hgh without a prescription? I have read online that it is illegal however, majority who have travelled abroad without a prescription have said that it is fine and they don’t really care. Majority of these people fly from the US so it may be different over there.
