Hello, dude! I haven't tried it myself, so I can't share mt personal experience. Clenbuterol is unhealthy for your health. It has unpleasant side effects. One advantage that some individuals want while using stimulants such as Clenbuterol is that it can help suppress your appetite, allowing you to eat less. However, the actual increase in calories burned by utilising it is little, generally about 3% or so. So do your proper research too.
Clenbuterol has been studied for both enhanced muscle mass and reduced body fats. Moreover, it remains in the body with an active effect for about 6 days after consumption.
You can try Anavar, Sustanon or Winstrol for melting stubborn fats. But do your background research for all of these to see which one has the least or no side effects regarding heart problems.
