A lot of the peptide brands you see running Google Ads right now are cloaking, meaning Google’s reviewers see one page and the visitor sees another. It works until it doesn’t, and when the account gets caught it’s usually gone for good along with the Merchant Center. So copying what they’re doing is a risky way to build a business.
The other thing worth knowing is that most of the money in this niche isn’t actually coming from the ads. From what we’re seeing with the peptide brands we work with, the bulk of revenue comes from organic search and from the back end. Someone searching for a specific peptide is already close to buying, and once you rank for those terms you’re not paying for every click or worrying about an ad review.
So if you have a budget, you’ll likely get a better return putting it into organic search than fighting Google Ads approvals.
If you do still go the ads route, make sure your back end is solid before you spend anything. That means email capture on the site, welcome flows, abandoned cart and browse abandonment emails, and post purchase flows for reorders. Peptide customers tend to buy repeatedly, so the profit is usually in the second and third order, not the first click. Without that in place, paid traffic in this niche rarely pays for itself.
