Rather than stimulating your body, niacin is able to unlock the energy that is available within the calories you consume. This means your body is able to achieve sustainable energy without any crash. While taking niacin pre workout supplements, niacin may also lead to flushing sensation which causes the skin tingle. When you realize this, known that this is normal and the effects will disappear after a few minutes. Just don’t worry if your pre-workout supplementation contains too much niacin. In fact, the more niacin, the better the results.
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.
