Google Ads
ℹ️ Note: this seller also runs Google ads for research peptides, a category Google's own policies prohibit, visible in Google's Ads Transparency Centre (UK). Worth knowing, but it doesn't bear on the question that puts it on the independently-tested list: its certificates are its own and genuine.
