I wasn't sure what you meant - thanks for clarifying. On the "mixed drug cocktails," are you referring to the "Duchess Cocktail" that was used extensively at Sochi?
This is the ambiguity in simply saying drugs "work".
When I speak of steroids, testosterone, etc., "working" I was thinking of strength events, and not endurance events, particularly women's performances from the '80s, as well as recent Russian success favoring the women taking mixed drug cocktails.
I don't "believe" steroids work for distance events, although I remain open to the possibility still for the women, that the increased muscle strength may be a factor.
Sorry for the ambiguity.
And increase muscle strength may be factor for some women in the mid-d events, but for others it doesn't seem to be. Just look at the Russian trio in the 800 final at London; Savinova, Poistagova & Arzhakova. All three are thin, slender, petite without any muscularity. Poistagova could compete for "Miss Russia" & Arzhakova looks like a HS girl. Lol. According to McLaren, Savinova said she was using oxandrolone & EPO, Poistagova said she was using EPO & took "ten oxandrolone pills" during the summer period of 2012.
With Arzhakova there's no evidence of androgen use but she was later DQ & sanctioned for hematological anomalies.
So, Savinova destroys the tank, Poistagova finishes 3rd & runs her PB (1:57.53) & Arzhakova finishes last but runs one of her faster times. I'm not seeing where any lack of muscularity was a limiting factor for either Savinova & Poistagova. These two were the thinness in the field and near skin & bones type builds. So, whatever roids they were taking didn't seem to build any muscle mass. Looks like more of a benefit from O2-vector doping put these two in the hunt for medals, IMO.
And that brings up my point of contention that the 800m is an endurance event with a major aerobic component that would benefit from O2-vector doping.
