we already know the answer to this, it is because they aren't gonna approve something for PED purposes and that is what sarms has been shown to be good for. there are sarms that have been abandoned, and some that are still in the process of being approved. to be approved you have to show it has health benefits long term. even so it means nothing because in fitness we take the PED and jack up the dose regardless just as mobster said earlier in the thread. example nobody uses 100mgs of test and 1iu a day of hgh to compete in a show, not even a normal joe who is a weekend warrior uses those types of dosages. we like to JACK UP the dosages. 200mgs of test? not enough. 300? 500? okay now you are talking but then we gotta add in another injectable and an oral too. that is how we stack steroids. for sarms, it would be the equivalent of running 2mgs of RAD with 2.5mgs of GW for a cycle. literally makes no sense. so approval or not it won't make a lick of difference how we use them, if they got approved tomorrow nobody is going in to see their anti aging doctor and request to fork over $$$ to run therapeutic dosages when we go can online and buy them from umbrella for cheaper and run dosages that actually boost athletic performance.
Again, I don’t know why they didn’t continue, but Cardarine isn’t a SARM, which may be a technicality here, but in drug development it isn’t. It’s a PPAR agonist, which I am sure you know, and that is a category of drugs that companies have been trying to develop forever, because of their beneficial uses outside of sport. For example, Telmisartan is the only other PPAR-D agonist known, and it is a bit of a wonder drug because it does what PPAR agonists do. To wit, it lowers blood pressure, improves lipids, improves glucose management, improves metabolic outcomes and improves cardiovascular performance. Unfortunately, it doesn’t do any of these things as well as Cardarine does.
All of that was basically my point. Cardarine is exactly the kind of drug that people have been trying to develop for its cardio/lipid enhancing profile, which, as far as I can tell, is exactly why people here take it on cycle, as 10% performance enhancer, 90% health prophylactic. If you asked a drug company if they would like to be the ones to develop an alternative to Micardis/Telmisartan that works 3-4x as well for improving health markers, any one would jump at the chance, which is why I am personally skeptical of the safety profile of a drug that was dropped when its benefits were so high.
As I’ve said, I think it’s probably safe, just outside my risk matrix. But I don’t think it was discontinued because it was a SARM, it isn’t, or because it improves athletic performance. There are tons of approved drugs that increase athletic performance as an ancillary benefit to their other features. People have been searching for a better PPAR D agonist for a long time, and often they find cancer issues. They will keep looking, it just isn’t going to be Cardarine, and none of us really knows why at this point.
TL;DR version: In a country that is filthy with metabolic syndrome issues, every drug company and the FDA are dying to push through the ultimate lipid/BP/glucose management drug, it’s probably not a conspiracy against steroid users that this drug didn’t make it.
