When using Trenbolone for a cutting cycle, you should supplement your weightlifting or resistance training with about an hour of cardio or aerobics every other day. This will provide your body with the calorie-burning potential it needs to shed adipose tissue and give you the lean, shredded look you crave. You will also need to consume far fewer calories than on a bulking cycle, and these should be comprised of plenty of protein and complex carbs. These macronutrients will help you maintain your existing muscle tissue and provide you with the energy you need for those intense workouts.
The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . 
Of course some will always want more and while we advise you stick with just testosterone there are additions that can be made safely. One option would be to stack Dianabol with your testosterone the first 4-6 weeks of the testosterone cycle. Another option would be to stack Winstrol the last 6 weeks of the cycle and depending on your goals this will determine which one of these steroids you choose. It is however not recommended that you choose both as both are highly liver toxic and both could bring too much undue stress to the liver. Sample outlines of such beginner steroid cycles might look like this:
