Im not sure what you mean by evidence and sourcing different breeders. If you repharase im happy to address that.Your argument is that the 3 clinical trials, whose durations were in terms of weeks, that did not measure any parameter of carcinogenicity as an outcome, are not only good evidence that cardarine is not carcinogenic in humans, but better than the standard that is actually used to determine that outcome?
Do you have evidence that the 2-year rodent carcinogenicity bioassays were susceptible to this theoretical genetic drift problem by actually sourcing from different breeders or colonies?
Have you considered the fact that if there was consensus that the carcinogenicity standard was not a good one; it wouldn't be used as a standard?
With regards to considering the standard, i was suggesting it could be reconsidered and evaluated by the scientific community. I dont have that answer, nor do I know how they could even approach looking at new candidates to use as subjects. I just think its worth exploring. Maybe even AI takes over at some point and we dont need the rodent subjects.
I did see someone else said that cardarine is "highly carcinogenic" . I wasnt aware of a table or scale which labels the level of carcinogenicity. I'm also looking at a bottle of protein powder as i type this reply and there is a prop warning from California stating the product is carcinogenic. Would consuming just one shake 3x per week lead to cancer? What about 3 scoops twice per day, or any other combination? Or is it just take it once and your looking at a probable cancer diagnosis later in life that can only be traced back to this protein. Nothing else contributed. Much like the smoking is carcinogenic argument, i do believe that other factors contribute to a drug going from carcinogenic to developing into cancer such as certain predispositions, genetic mutations, multiple factors, drugs, environmental exposures coinciding simultaneously with the use of the studied drug, administration, etc. It is impossible to evaluate all of these factors together at the same time therefore i dont see any possible way to say one way or another if a drug that has carcinogenic properties will lead to someone developing cancer because a rodent taking nothing but the said drug developed cancer. Its far too complicated for my mind to unpack.
