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.
This is a prohormone to trenbolone. Unlike previous "tren" prohormones, this one actually converts in the body to trenbolone. Previous "tren" PHs converted to the structurally similar - but markedly weaker dienolone. Conversion to trenbolone should be high, so effects should be identical to the injectable form - with the exception of the famed "tren cough". Whatever the explanation for "tren cough" (and many have been suggested), since it's a reaction to the sudden parenteral introduction of some compound directly into the body, it's highly unlikely that any orally administered compound will have the same effect.
