List the "three, four or five different theories about" Clenbutadorgate

[la.margna]

According to JV "there could be three, four or five different theories about it", so could we just summarise these three, four or five theories about what caused the Clenbut reading and why it is so low? Please by excluding the ridicolous meat story, only serious stuff from cyclingnews' science department please! thanks!

Haven't we got enough threads discussion this particular issue?

 

[hrotha]

I thought the RFEC's report covered these four main theories?

 

[la.margna]

I thought just theories, but not the official theories, the real ones. no discussion. but just an idea, so they can be found in a compact thread. but of course, mods feel free to remove the thread if considered to be covered by others already.
