I think asking personal opinion of what worked better doesn't really produce
usefull information since we can't discuss dosages, administration mode,
person's weight, nutrition, etc. We've also don't have access to the patient's medical records
and don't have access to labs to sample various blood components at various times, or someone measuring in a systematic ways results. Not to mention the notion of proper sampling is such a diverse community.
There's a reason why medication studies take up to 10 years
and hundreds of million, and we are talking about one med administered in one mode,
under very controlled circumstances.
Another thing, "results" depends on so many factors that I'm not even sure its possible
to create a study that produces meaningful results.
Anyway, the chance there will be a conclusive study on our medications is because its simple, there is not enough cash in it.
