It’s been common knowledge that any Chinese ED supplement on Amazon that is effective has Viagra in it. This is not a bug but a feature
And who knows what else!!!
I'd never ingest anything that has Chinese provenance. Chinese garlic comes to mind as the latest thing to try to avoid. Not sure if true but it seems to be grown in sewage. I'd rather be safe and avoid that altogether.
If that's your concern, you shouldn't be worried about just China. It's done in America as well.
