Because steroids are lipophilic, they diffuse easily through the cell membranes, and therefore have a very large distribution volume. In their target tissues, steroids are concentrated by an uptake mechanism which relies on their binding to intracellular proteins (or " receptors ", see below). High concentration of steroids are also found in adipose tissue, although this is not a target for hormone action. In the human male, adipose tissue contains aromatase activity, and seems to be the main source of androgen-derived estrogens found in the circulation. But most of the peripheral metabolism occurs in the liver and to some extent in the kidneys, which are the major sites of hormone inactivation and elimination, or catabolism (see below).
If you want to know how to inject steroids , the first thing you need to know is how to prepare for the injection. You know you need to stick it into the muscle tissue, and we’ll go into the specifics of that later on, but there’s more to it than that. There are eight specific steps you need to follow when injecting anabolic steroids, and while that may sound like a lot the whole process shouldn’t take but a minute. Failure to follow these eight remarkably simple steps can result in complications such as infections or simply very uncomfortable injections, and an unnecessarily sore injected area.
