Bro you are in the UK and we enjoy reasonable AAS laws. ANY source that even thinks about offering a service should be able to provide all ancilleries as well as a decent range. Your source sounds crap.
For your info clomid, Nolva, Arimidex, Proviron etc etc etc are all readily available in UK as they are in other countries. It is not your loacation but your shit source that is at fault
be careful as i am sure you will get loads of solicating e-mails offering you services now so be warned.
Wrongun!
