as far as i am aware the possession of steroids for personal in the uk is legal, so i cant see how they can take a small quantity when leaving.
http://www.steroids-uk.com/steroidlawuk.html also i got the letter below for a site quite some time ago its a reply to some one asking about the importation of steroids
"Dear Enquirer,
Thank you for your recent enquiry to the MHRA.
We can confirm that there is no requirement for a member of the public to notify the MHRA of the importation of medicines for personal use and the legislation does not restrict such importation. The MHRA therefore has no objections, provided that the imported medicinal products is used only for your own personal use and that you do not sell or supply imported medicines to anybody else (including family members).
You should be aware that up to a 3 month supply of a medicine is considered to be an acceptable quantity for personal use, HM Revenue and Customs can prevent importation if large quantities are being imported and/or they have suspicions that the product is not being imported for personal use. You can read more about HM Revenue and Customs from their website at the link below:
http://www.hmrc.gov.uk/ We also advise you to investigate whether the product(s) you wish to import are categorised as controlled substances in the UK - Controlled drugs are regulated by the Home Office under the Misuse of Drugs Act, and can require a licence to allow their entry into the UK**. The Home Office have published a list (although not exhaustive) of controlled substances on their website and you will need to contact them directly for clarification on whether a Home Office licence is required for importation into the UK:
http://www.homeoffice.gov.uk/drugs/ We advise that any posted packages containing medicines should contain a copy of the prescription and/or a letter from the patient's doctor explaining why the product(s) are required, we suggest that the package is clearly labeled on the outside stating the contents of the package and that the products are for personal use. We also strongly advise that the medicines are kept in their original packaging and that they are transported in accordance with storage conditions specified by the Manufacturer (this not only helps identify the medicines, but also helps ensure the product's stability).
Please don't hesitate to contact us again if you need further assistance with this, or any other queries.
Kind Regards,
