In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track.  In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." 
If you planning to buy anabolic steroids online , you must understand about the chemical structure and formula behind the manufacture of steroids to avoid side effects, that's why you should do a post cycle therapy after your steroids cycle . The steroids are synthetic hormones which can enhance the potential of body to stop muscle breakdown and prevent faster growth of muscles. Athletes usually take steroids to improve aggression, speed, stamina and strength. Athletes use steroids to lift heavier weights, run faster, jump higher and improve their power while performing in competitions.
Tbol is 17-alpha-alkylated (17aa) to survive the first pass through the liver. You need to be very careful when stacking it with other oral steroids at moderate to high dosages due to potential kidney, liver issues. This means you must use a liver/kidney support supplement with it, such as N2Guard . I suggest sticking to a maximum two (2) orals per 6 weeks regiment and never stacking more than two (2) oral-steroids at a time. Although tbol generally has less side effects than other AAS, it should still be respected, as it is a powerful hormone.
