Can I have Botox to reduce masseter muscles whilst on anabolic steroids (anavar)?

Thank you for your question. Botox in the masseter region usually takes longer than in the standard areas to take effect. I tend to use anywhere from 15 units (conservative treatment) to 50 units (for someone with really strong masseters) on each side to get the desired result. It may start within the first week but I tell my patients to wait three weeks before doing a more thorough evaluation. The treatment typically lasts longer than the forehead/crows feet/frown regions. It is also a gradual onset of the return of masseter function. I have tried the masseter injections myself and space the treatments around 4 months apart, but use smaller doses to maintain the effect. I normally know the effects are wearing down when I start to clench my teeth more heavily at night when asleep. Once you stop using Botox, the masseter muscles will return to their original baseline when the effects of Botox wears off completely.Being on steroids should not influence your results.

this is something I perform daily and many of my patients are on AS for bodybuilding and other purposes.  the steroids do not effect the botox.  however, depending on how large your muscles are and how strong they are, you may need higher doses of botox to get the "contouring" results.  I suggest going to an expert injector for this.  Best, Dr. Emer.

Yes. This should be fine. Botox interrupts the connection between the nerve ending and muscle, itself, so anabolic steroids shouldn't interfere with the effect. To be safe, also mention this to your physician injector to ensure that they agree that this is a wise thing to do. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon
