Since the sale, purchase, possession, use and transport of steroids is illegal and a felony in the USA and many other countries, the businesses that do it have to make sure payments are not trackable. Otherwise, governments will seize the bank accounts of businesses doing such and quite possibly the accounts of individuals purchasing said products just as they would with anyone dealing in any other illegal drug. The only exception is if you have a doctors prescription and deal with a legal pharmacy, but then you are not going to get enough to get the results you are looking for. So as long as you are buying Oxandrolone without a script you are on the naughty list of law enforcement if caught.
As for cardarine it is illegal to be sold for the purpose of human consumption. It is an experimental drug not approved for use in humans as the initial tests sent to the FDA included some side effects not considered acceptable by the FDA. You are only allowed to purchase it for use in experiments and it is only to be sold for use in experiments with animals. So again you are in the black market if you are buying said product for personal use.
