Checking on whether or not a supplement is FDA approved is extremely simple. All you have to do is use this Drugs @ FDA catalogue to be able to see which drugs are FDA approved or not. Your supplements should be in there too, if they’re approved. If your drug or supplement is not FDA approved, this could be for a few different reasons: from the idea that the approval hasn’t been completed yet, to the process was never started: or, worse, the product failed inspection.
Make sure you look into your supplement under whatever rules or specifications you’ll have to follow to get it: you don’t necessarily even want a supplement that’s difficult for you to access, because it’s illegal — because there’s been cases of poisonings because of it. That’s why it’s always best to buy from a certified seller like UK SARMs.
