Primobolan (Metenolone) is an interesting medicine that has many health benefits. However, like you say, it cannot be prescribed in the US.

The reason for this is that the FDA has decided that Metenolone has “no practical medical use”.

Any drug (including steroids) that is not approved by the FDA is considered an “unapproved” drug that exists outside of the scope of standard medical procedures in the US. Unapproved drugs may have health benefits, but it will remain unapproved if it is determined by the FDA that the unapproved drug confers greater health risks than approved drugs where the side effects are better-understood.

Since Primobolan is proven to help with bone density and anemia, it would be potentially be able to be prescribed for these conditions. However, at the time it was being reviewed for FDA approval, there were studies that showed it could cause heart enlargement and another study showed it may cause cancer..

Because there are drugs that treat low bone density and anemia that are considered safer, the FDA would not approve Primobolan.

This is interesting, because the DEA has labeled Primobolan as Schedule III. Drugs that have no currently accepted medical use (as the FDA has defined Primobolan) and have a potential for abuse are supposed to be listed as Schedule I.

So I’m this case, the FDA and the DEA are at odds. And these are only 2 of about 12 regulatory agencies responsible for prescriptions/pharmacies/medical practices. They rarely agree with one another. Welcome to the US.
