I have been involved in one way or another in the cycling industry since the 1980's and have met many who worked with GL, rode with GL, sponsored GL and were either friends or business associates, and I still have never heard a single whisper or rumor about him ever doping.
One could argue that he might have been doped without his knowledge, but there isn't anything I have ever seen, or anyone I have ever heard from, to support that claim with any facts.
I remember during the 1986 tour I heard he was even doing additional urine samples and photographing his urine samples to make sure they weren't tampered with since someone warned him he might be sabotaged. He was also the first I remember to really try to get the tour organizers to test more riders, more, randoms, and every starter before the race like they do now...
In my opinion he was clean. I am not so sure of any the other tour winners since.
