If you sell peptides or research compounds, paid social and search are a narrow road. None of the four big ad platforms name research peptides in their policies, but every one has rules that reach them. Here is what each policy says, read on November 1, 2026.
Meta (Facebook and Instagram)
Meta's Drugs and Pharmaceuticals policy prohibits ads that promote drugs, products or supplements Meta considers unsafe, and Meta decides what counts as unsafe. Its named examples include anabolic steroids and human growth hormone. Prescription drugs are a restricted category: online pharmacies and telehealth providers need LegitScript certification plus Meta's written permission, and can only target adults in the US, Canada and New Zealand. Weight-loss products and supplements are limited to people 18 and over under the Health and Wellness policy.
Google Ads
Google prohibits unapproved substances regardless of any claims that they're legal. That covers supplements with active pharmaceutical ingredients, products that imply they work like prescription drugs, and products marketed as treating disease without government approval. Google's published list of unapproved substances doesn't name research peptides, but those rules are the ones that apply. GLP-1 names like semaglutide and tirzepatide sit on Google's restricted prescription terms list, which needs healthcare certification.
TikTok
TikTok allows US prescription and over-the-counter medicine ads only with proof of FDA approval, shown to adults. Its dangerous products policy doesn't allow prescription drugs promoted for enhancement, performance or weight loss. Research peptides aren't named, and a product without FDA approval has no route through the medicine rules.
X
X doesn't allow health and pharmaceutical ads unless a country's section permits them. In the US that list is accredited pharmacies, pharmaceutical manufacturers, medical devices and licensed telemedicine, with X's authorization first. Supplements aren't on the US list.
Where that leaves a peptide brand
Paid acquisition in this category is narrow. The customers you already have, and the people who signed up to hear from you, are the audience you can reach whenever you want. That's why email and SMS carry so much of the revenue for peptide brands: a welcome series for new signups, cart and checkout reminders, restock and launch campaigns, and post-purchase emails that bring buyers back.
- Collect emails and phone numbers from day one, with a real opt-in.
- Send from your own domain, so reaching your list never depends on someone else's account.
- Keep every email and text in research-use language: no dosing, no health claims.
- Track which emails and texts actually drive orders, so you know what works without ad data.
