Steroids, whether injected or taken orally, travel through the bloodstream & bind to receptor sites in the body. They obviously increase the bodies anabolic(muscle building) capabilities, but they increase the bodies ability to synthesize protein better as well. This allows your muscles to recover/repair quicker from workouts.Anabolic steriods also increase the blood volume in your body & muscles----leading to better endurance and better vascularity. Gear lowers cortisol levels---cortisol is catabolic (it is a hormone that is muscle burning--it is released when the body is under stress & needs energy-uses muscle for that energy)....A.S. also increases the amount of water retention in the muscle cells---(hence the concept similar to the that of creatine---properly hydrated muscles are more anabolic then under-hydrated muscles.) Gear increases the bodys ability to produce creatine phosphate, which allow the body to use enzymes that increase energy levels while training.
