On the idea that doping makes permanent changes. With respect to steroids and muscles, maybe, but very dubious for changing blood parameters, which of course is the major goal of doping in cycling. If you stop taking EPO or blood transfusions, your HT will fall to its former levels, that is very well established. There is no permanent physical change there that I'm aware of.
As for a rider being psychologically changed, because he's had experience going beyond his former limits, seems to me that could work either way. He could also be somewhat devastated at not being able to perform at the level he could while doping. I believe several riders who came back after doping mentioned that, and it surely is a major reason why they return to dope.
Think of the early 90s, when riders who were not on EPO suddenly found themselves dropped by guys they had easily stayed with if not beaten before. A former doper must feel a lot like that when he returns to the peloton clean. It's very much an addiction.
How much research have you done?
On such popular drugs as:
- Testosterone & other AAS
- IGF-1
- HGH
Could any of these impact capillary density, for example? Will that simply disappear?
Your blood supply may replenish itself after 120 days, but will your muscles, bones and organs all disappear? Please bear in mind that there is little doping, these days, during the competition. Thus, gains other than blood supply and composition, are of a more permanent nature.
(anything like increased heart size... changed body composition... ?)

Enlargement of
o Hands and feet
o Nose, chin, tongue and ears (remember Pantani?)
o Organs: heart, liver, bowel
What about Gene doping?
(Research on this post yielded an interesting study linking AAS' to testicular cancer:
http://www.ncbi.nlm.nih.gov/pubmed/10526287
"high dose doping with androgenic anabolic steroids could have played a cocarcinogenic role in the development of the tumor in this case")
- Know any athlete to have had testicular cancer?
- Alternately, know any prematurely bald cyclists?
- Know any female cyclists with excessive hair growth or reduced breast size?
- Anyone with Necrosis ("rotting") of Femoral head (hip joint)?
Sure, these last points are non-beneficial, but they are definitely long-term.
Are there no possibilities of long-term beneficial impacts of doping?
