Travel by Bag or Post?

Could someone possibly please clear this up for me…
I want to bring a single cycle worth of Test E and dianabol into the UK from Thailand. Do I post it or can I bring it in my luggage?
I have read that it is legal for personal use but I would like to confirm this with someone experienced…thats why I have come to the T brothers…Thnkx

Thanx BBB, thats just the kind of logic I needed to hear…u da man!
