Bodybuilders and other users routinely take dosages that are hundreds of times higher than the medically recommended dosages. Users often combine multiple anabolic steroids into stacks, and alternate such usage with periods of abstinence called cycling. A typical stack will last 6 to 12 weeks and be followed by 2 to 4 weeks of non-usage. Despite the lack of medical evidence to “prove” the point, it’s safe to say that steroids do promote tremendous gains in muscle strength and size. The anti-steroid advocates who say otherwise obviously don’t spend much time hanging out in gyms. It’s one thing to work with rats in a lab, but another thing entirely to use human subjects.
