ALL AAS, make your body retain nitrogen (the "N' in NH3 that makes an amino acid), so when dieting your body normally tears down muscle, as its metabolically expensive to keep, and uses the amino acids reclaimed as either fuel (via gluconeogenesis) by converting the amino acids to glucose, OR excreting them in the urine. AAS retain the amino acids, so more are available to re-build muscle, so when dieting, more fat than muscle is lost, especially by doing cardio (burn fats) and weight training (requiring the muscle to be maintained/re-built).
In order to achieve the fat burning benefits of Clenbuterol, you still have to watch your diet. Many people want to just take a pill and have the weight just fall off by itself. This just isn’t the case. Clen is pretty powerful stuff, but you have to make a little effort yourself to have it work right. There is no magic pill that will help you lose weight and gain muscle. Clenbuterol can work great for you if you include a healthy and sensible diet with exercise. You will truly notice all the results you have been hearing about if you follow a program with it.
You need to stack test with that anavar bro. Even though it is a mild steroid compared to other compounds, it is still going to shut down your natty test and your going to feel like shit soon, not be able to use your dick, and wont make the gains your hoping for. Stop taking the var by itself for now, its only been 3 days so that wont hurt you to stop now, Go buy 2 bottles of test e or cyp and run that at 500mg a week for 10-12 weeks. You also need PCT shit. HCG novla and clomid. Add the var for the last 6-8 weeks of tyhe cycle. Id wait bro, do your research, get all the gerar you need before you use it including PCT. If theres one thing people hate here on eroids its oral only cycles so I dont know how much help your going to get, but that is the best advice I can offer.
