When looking for an online pharmacy to purchase Adderall from, be sure to do your research to make sure that the site is legitimate. There are many scams out there that will try to sell you fake or counterfeit drugs, so it is important to be aware of these before making a purchase. A good way to tell if an online pharmacy is legitimate is to check if they require a valid prescription from a licensed healthcare provider. If they do not, then it is likely that they are not a legitimate source for Adderall.
