once the suplemments arrive into Qatar they will go to Customs and also to the Health authorities to give the clearance, then you will receive your stuff.

If health authorities do not issue the clearance your stuff is simply seized and you might probably end up loosing your money.

Aramex provides the facility to shop in the US & UK and bring it into Qatar however and once again upon arrival the merchandise will need the approval and clearance of the Health Authorities so you can receive it in your hands.

Better call them to check if they can help you on this
