This is a great question that, unfortunately, cannot be answered in just a couple hundred words. There are important issues that focus on educating one's self prior to embarking on such a course of action, particularly the downsides of using steroids – the side effects, the proliferation of fake gear, getting off of them, getting blood work done, etc. And, the fact that buying, selling and transporting them is (in America) still a felony, not to mention banned by all sports federations. All very important salient issues that require a lot of space to do justice.
Equipoise has one of the longest detection times of any anabolic steroid; if you are a tested athlete you are urged to forgo its use. Equipoise can be detected in the urine for months even after use has been discontinued; some studies have claimed they can trace the drug back to as far as one year from the end of use. In most countries Equipoise is not legally obtainable; in most cases only through purchase from an underground lab can this drug be obtained. For that reason it is very important you understand the laws in the country you live.
