iirc lance used Test, Cortisone, EPO, Blood doping with his own saved blood, GH, diuretics probably more stuff, designer stuff was surging around that time too. Used all that for the same reasons any athlete would, most of them are fairly obvious. The cortisone was for weight loss (probably injuries too) but I've never been able to nail down how they used it for that purpose exactly, seems to be a deep secret or at least no one will tell me lol.
I bet he used a bunch of other stuff but the things I listed are what he was caught for or admitted to. I fucking hate that guy btw, I'll be grumpy about even hearing his name till my head hits the pillow tonight. Not the drug use itself but the way he abused a fucking ton of innocent people surrounding it, pretty much ruined some lives, careers and financial situations. I dream about meeting him when I'm with one of the boys "Holy shit you are Lance Armstrong aren't you? Hang on I want you to meet my son!" "Son it's your lucky day, this is Lance Armstrong! He is probably the biggest fucking scumbag loser assholes you will ever lay eyes on in you life! Now get the fuck outta here lance before you get hurt"
