Groups on the internet, such as the SS forums, have probably left untold amounts of guys disappointed with how they've looked after 3-12 months. Meanwhile, the "bro" who goes to the gym and does curls, bench, shoulders and a few chin-ups and leg presses totally blows the SS "student" out of the water, getting bigger arms, shoulders, pecs and upper back without that much weight gain. Thus trashing the SS mantra of people being unable to induce significant localised hypertrophy, which skinny fat guys benefit from aesthetically.

In the UK, anabolic steroids are classified as Class C substances. Their possession can lead to a 2 year jail term, while their production and supply can lead to a 14 year jail term. But many countries do not have strict laws. In some places, you can even buy it over the counter.
