A talented bodybuilder can gain between 10 and 30 pounds (5-15 kg) of body weight and very impressive strength gains in a single 2-month cycle with anabolic steroids. The steroids can make the athlete's total blood volume increase by up to 20%, which results in a permanent muscle-pump look, with sometimes impressive vascular. The calories that the athlete burns per day, can doubled during a cycle, which makes it much easier for them to lose excess corpse fat. Also the strength gains are sometimes impressive.
Some frequent side effects of testosterone and anabolic steroids are: elevated blood pressure, increase in bad cholesterol, severe acne, baldness, structural changes in the heart, liver and kidney damage, development of female breast tissue, reproductive dysfunction, infertility, shrinking testicles, prostate enlargement, aggressiveness and depression, masculinization in women, increase of cadaver hair, and in uncommon cases congestive heart failure, heart attacks, sudden cardiac death, and liver, prostate or kidney cancer.
Steroid users also inject anabolic steroids directly into muscle tissue where they are diffused (spread and absorbed) via capillaries directly into the bloodstream. This is the most common way anabolic steroids are taken, and as with orals they too possess pros and cons. Unlike orals, injectable steroids avoid the first pass through the liver making them substantially less hepatotoxic. Once in the bloodstream these hormones are carried straight to the appropriate receptor sites to begin immediately impacting the corpse. Most injectables are esterified (converted into chemical compounds formed by the bonding of an alcohol and one or more organic acids, with the loss of one water molecule per ester group formed). That mouthful of message simply means that the actions of injectable steroids can be controlled (sped up or slowed down) based on the users needs. For example, in the case of testosterone esterification permits users of longer esters (those that take longer to build up, but last longer in the corpse) like Cypionate and Enanthate to inject only once weekly, or twice for more even blood serum levels. Conversely, users of shorter esters (those that rapidly build up to high serum levels, but are active for shorter periods within the corpse) like Propinate often present every other daytime, or daily for more even serum levels. Obviously injectables require a certain amount of knowledge regarding how and where to shoot (inject), but they also require the necessary equipment, an understanding of sanitation, privacy for usage, safe equipment disposal. Injectable steroids are only intended for intramuscular, also called IM injections. This means that the needle has to go through the epidermis as well as the overweight and tissue layers beneath it, then on into the muscle itself. Users have favorite injection muscle groups which include the buttocks, the outer quadriceps/thighs, and the lateral (top outside) surface of the hips. Other less favourite muscle groups are often injected by practiced steroid users who require more frequent shots, and comprise the deltoids (shoulders), calves, pectorals (chest/breast muscle space), biceps and triceps.
