Swiss Olympic announced on Thursday that it instituted the bans against Roger Nachbur, a 30-year-old road cyclist, and Reto Eigenmann, 41, a speed skier.
The sanctions marked the first time the committee has implemented anti-doping rules in cases of banned drugs bought through the internet.
Nachbur was found in possession of clenbuterol, a performance-enhancing drug, and EPO, banned substances which he ordered on the internet.
Spanish cyclist Alberto Contador was banned from professional cycling for two years after he tested positive for clenbuterol at the 2010 Tour de France.
He was stripped of his Tour de France title, although it was discovered that Contador took the drug indirectly through a contaminated food supplement.
The Swiss committee’s disciplinary body banned Nachbur from competing until August 23rd 2014.
He was also fined 500 francs and assessed 1,700 francs in costs, including expenses incurred by Antidoping Suisse.
Eigenmann was found guilty of ordering online testoviron and trenbolone acetate, both steroids, and clomifene, an anabolic agent.
He is also banned from competing until August 23rd 2014.
In addition, Eigenmann was ordered to pay 1,700 francs in costs.
Swiss Olympic’s charter of ethics calls on athletes to say “no to doping” and the use of “health altering” substances.
