Anabolic processes tend toward "building up" organs and tissues . These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules . Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids , which stimulate protein synthesis, muscle growth, and insulin .  The balance between anabolism and catabolism is also regulated by circadian rhythms , with processes such as glucose metabolism fluctuating to match an animal's normal periods of activity throughout the day. 
Whether you want a Testosterone Cycle, Cutting, Bulking up or a Weight Loss Cycle , you should make the right choice before you start. Make sure that you decide if you want to cut, lose weight, or gain muscle. Maybe even lose weight and gain muscle all at the same time.
A healthy diet along with a good protein supplement will greatly improve performance in any good Cycle. Remember that by losing fat around the body you will increase your strength to mass ratio and improve lean muscle tissue, giving you that lean physique appearance.
Bulking and Cutting Cycles - Those individuals who already have a lean physique wont achieve fat loss gains as quickly as those with more weight and therefore would more than likely opt to go for a combined all in one Bulking and Cutting Cycle to start with.
