Question

What were all the cyclist using that was banned?

Answer 1

steroids man. they are illegal in pro sports competition especially injectable types.

Answer 2

check out EPO dude, steroids designed for endurance i believe

Answer 3

as mentioned,Erythropoietin (EPO) is the drug. When used as a performance enhancing agent it is called Erythropoiesis Stimulating Agent (ESA).  

Answer 4

Historically, many different drugs have been used in attempts to enhance sporting performance. Strychnine, cocaine, heroin and ethyl alcohol were in common use at the turn of the century, but they were later supplanted by amphetamines, pseudoephedrines and anabolic steroids. Caffeine has remained popular for over a hundred years and anabolic steroids have been in steady use since the early 1960s.

Some of the newer drugs are the testosterone precursors, dihydrotestosterone, clenbuterol, growth hormone, insulin-like growth factor, insulin, erythropoietin and beta-hydroxy-methylbutyrate.

Insulin is allowed for diabetic athletes only. As far as I know,  beta-hydroxy-methylbutyrate is allowed, the rest are banned.

Answer 5

Two of the riders in the Tour de France were caught using a new form of EPO called CERA (Continuous Erythropoiesis Receptor Activator).
