In reply to Chris the Tall:
You are right that things need to testable, but there is no need to provide a dosage guidance.
Anyway, from your link:
... There is no extra benefit for anyone who might not be asthmatic. If an asthmatic took a few extra puffs, they might feel some mild stimulation. Like a jolt of caffeine. Beyond that, there are not much additional benefits to performance....
Overall I get the expression that Dr. Bassingdale is referring normal, therapeutic doses, which indeed suffice to relax the airway musculature and not much more (as low absolute amounts will do the job). Interestingly sprays are not the ideal mode of delivery, full nebulizers work much better and you can overdose easily.
I also doubt that Froome used Salbutamol pills or injections on that day, even though it is a possibly way to get the high readings. I do not see the point ther, that would make much more sense in training rather than during the race, where a stimulant effect may be more interesting.
My suspicion that has come from the last days of discussing the topic is that they may have used the Salbutamol as a PED, possibly even staying inside the absolute limits, by not distributing that dose across multiple puffs but by concentrating it in time.
The idea would be to generate a short spike that exerts a stimulant effect, possibly stronger than the few puffs referred to above, and still would allow them to claim that they had stayed within the rules.
The adverse finding could then come from bad timing (e.g., the urine sample being collected a bit earlier than expected, from the first piss after the race rather than after a period of rehydration).
No pity, though, as such a strategy would still amount to subverting the spirit of the regulation, which was be to help people suffering from asthma, not to allow them to exploit the side effects of the drug.
