Anabolic steroids can be taken along levetiracetam. But why do you want to take anabolic steroid for body building?? There are natural ways available for body building. On long term use of anabolic steroids can cause fluid retention, high blood pressure, cardiomyopathy, sexual dysfunction, breast enlargement, liver failure, aggressive behavior, loss of hair, insomnia and prostate enlargement. Anabolic steroids can be used but only for medical reasons and under proper medical supervision. High protein content products for muscle building purpose are available such as ON’s serious mass gainer/whey protein and Muscle tech’s whey protein. But taking high protein may cause damage to basement membrane kidney causing loss of body protein (proteinuria). I suggest you to depend upon natural high protein content material such as pulses, meat, soybean, eggs, and fruits. Avoid anabolic steroids. If you still want to use it then use under medical supervision. There will not be any significant drug interaction between anabolic steroid and levetiracetam. Thanks
