Anavar is no longer manufactured by legitimate pharmacies, so no matter what anyone tells you about this or that brand being “pharm grade”, all anavar is being manufactured by underground labs and the typical dosage is 10 mgs a pill – far greater than the original intended dosing. Then again, how can you ever be sure what the exact dosage is? Different underground labs may use their own title for the drug, but most simply call it, not by its chemical name “Oxandrolone”, but by the original brand name of “Anavar.”
Anticoagulants: Patients on anticoagulants such as warfarin should be carefully monitored during anabolic steroid therapy as anabolic steroids may increase sensitivity to oral anticoagulants which may require a concomitant reduction in anticoagulant dosage to achieve a desirable prothrombin time (PT). Anticoagulant patients should be monitored regularly during anabolic steroid therapy, particularly during initiation and termination of therapy. Warfarin patients should have INR and PT monitored throughout androgen therapy and warfarin dosages titrated to achieve the desired INR and PT. Such patients should be monitored for occult bleeding.
