For the average May well, or Jane, anabolic steroids, or anabolic-androgen steroids are colloquially referred to as steroids; they are a synthetic derivative of an naturally occurring hormone. Without a doubt steroids are manufactured; to obtain them from natural sources would be prohibitively expensive. In particular anabolic steroids are generally chemical derivatives which mimic the effects of testosterone. Testosterone is actually the hormone of the androgen variant obtained in mammals, birds, reptiles, and other vertebrates. Testosterone is the primary male hormone in this human, and other vertebrate species. I agree that these are generally a lot of big scientific terms, please allow me to spell this out to you in a small amount clearer fashion. More info just vesit in the site
