You add a lot of assumptions to what I'd printed.So USAC had no budget or doctors, yet the cyclists were all (or a lot of them) doping? Did the cyclists just go and buy the drugs themselves? Did the coaches? If there was doping (and their likely was) on that team, then who provided the material? Who paid for it? I have a hard time believing that everyone was poor and didn't have the resources.
Generally the cyclists were given the general information and the opinion from coaching staff that their competition in Europe, Central/South America all used some form of recovery "aids". Any specific recommendations were given one on one to sourcing. It would rely on the rider to fund their activity. It involved a small percentage of team members as our riders would confirm.
Separately; there is the Greg Strock/Erik Kaiter case where they were actually given steriods, etc. without their knowledge while at 1990 Worlds by the staff. It is dry reading but the case files are pretty direct and demonstrates that USAC would go to those lengths if need be. This is also several years after Thom Weisel/Montgomery Securities started his cycling team and was closely tied to USAC. He recruited from the USAC pool for most of his early riders and continued with his funding into the 2000s for development programs. His firm also helped underwrite the IPO of a struggling biotech firm....Amgen.
