Can Botox Injected on Thighs To Reduce Muscle Mass?

Congratulations on your weight loss, dietary change and exercise.

Unfortunately it's not feasible to use botulinum toxin in the way you have asked about. It would require large amounts of botulinum toxin (which would be incredibly expensive) and would make your thighs weak.

If you take a look at the legs of models and actresses on the red carpet you'll notice that their shapely legs are due to a combination of being slim and having good muscle tone. So in fact muscle is actually very valuable when it comes to looking good! The other great thing about muscle is that it has a high metabolic rate - so when your muscles grow you burn more calories and lose more weight (unless you eat more food).

Try not to worry about what the scales say when you weigh yourself, focus more on whether your clothes are feeling looser. If you concentrate on cardio work rather than lifting heavy weights with low repetitions that will help to minimise the amount of muscle you gain with your training. But most importantly, remember that muscle is your friend when it comes to losing fat and getting in shape!

Why would you want to lose muscle mass?  That is the last thing in your body you would want to reduce.  Muscle mass keeps your metabolism elevated and helps you burn fat at rest.  Reducing muscle mass will drop your metabolism and make it more difficult to lose fat.  NEVER lose muscle mass!  It's the most valuable asset you have.  When weight training, use higher reps if you don't want to build more muscle.  To answer your question directly, Botox is not indicated to reduce muscle mass.
