This is not legal advice
What follows is a plain-English overview of the compliance landscape based on publicly available information. It is not legal advice. Brands operating in this category should work with an attorney who specializes in supplements, research chemicals, or telehealth compounds. The cost of legal review ($1K-$5K) is small relative to the cost of getting it wrong.
Layer 1: Federal (FDA + FTC)
FDA jurisdiction
The FDA regulates drugs, dietary supplements, cosmetics, and medical devices. Peptides are classified differently depending on positioning:
- Drugs — peptides intended to diagnose, treat, or cure a condition fall under drug regulation, which requires FDA approval (a years-long process involving clinical trials).
- Dietary supplements — peptides positioned as dietary supplements must comply with the Dietary Supplement Health and Education Act of 1994 (DSHEA), which prohibits disease claims.
- Cosmetics — topical peptides marketed for appearance changes fall under cosmetic regulation, less strict than drugs but still subject to false- claims rules.
- Research chemicals — peptides sold for research use only, with proper labeling and no consumption claims, are typically not regulated by the FDA as drugs or supplements.
The FDA has stepped up warning letters to peptide brands in 2024-2025. Common triggers: drug claims on dietary supplements, sale of compounded GLP-1 outside FDA shortage exemptions, and consumer-facing marketing of research chemicals.
FTC jurisdiction
The Federal Trade Commission regulates advertising and consumer protection across all categories. For peptide brands, the relevant FTC rules:
- No deceptive advertising (claims must be substantiated)
- Disclosure requirements for testimonials (Section 5 of the FTC Act + the Endorsement Guides)
- Required disclosures for influencer / affiliate relationships
- Truth-in-advertising standards for health and wellness claims
FTC enforcement on peptide brands typically focuses on testimonial and endorsement disclosure violations, which are easier to prove than substantive product claims.
Layer 2: State (varies dramatically by state)
State pharmacy boards
Each state has its own pharmacy board that regulates compounding pharmacies and prescription drug distribution within the state. For peptide brands:
- Brands that prescribe peptides through licensed prescribers must comply with each state's telemedicine laws (which vary substantially).
- Brands that ship peptides into a state are subject to that state's pharmacy board rules even if the brand is headquartered elsewhere.
- Several states (California, New York, Florida) have additional restrictions on certain peptide compounds that exceed federal requirements.
State attorneys general
State AGs have broad consumer protection authority and have brought multiple actions against peptide brands in 2024-2025, typically for:
- Deceptive marketing claims
- Sales to minors (when age-gates fail)
- Sales of compounds restricted under state law (even when legal federally)
- Subscription billing without proper disclosure
State AG actions tend to be costlier than federal action because settlements often include consumer restitution requirements in addition to penalties.
State controlled substance schedules
Some peptides are classified as controlled substances in specific states even when not federally controlled. The most common examples: certain growth hormone secretagogues in states with bodybuilding-supplement restrictions, and some research peptides flagged under state drug-precursor laws.
Layer 3: Platform (private rules, no due process)
Mainstream platforms apply private rules that don't have to comply with federal or state due-process standards. They can suspend an account with no notice, no appeal, and no recourse beyond limited internal review.
Meta (Facebook + Instagram + WhatsApp)
Meta's Advertising Standards have detailed restricted- product rules for:
- Unsafe substances + supplements
- Prescription drugs + online pharmacies
- Weight loss products
- Cosmetic medical procedures
- Drugs + drug-related products
Most peptide brands hit at least one of these categories. Enforcement is automated for the most part, but accounts spending $1K+/day cross into manual review territory.
Stripe + payment processors
Stripe's prohibited business list includes “research chemicals” and any merchant selling products with substantial regulatory uncertainty. They reserve the right to suspend any account that doesn't fit their risk tolerance, and they exercise that right regularly with peptide brands.
Shopify + e-commerce platforms
Shopify's Acceptable Use Policy prohibits research chemicals explicitly. Their automated systems catch new stores within days. WooCommerce.com hosting has similar rules. Self-hosted WooCommerce (running on your own VPS) isn't subject to these platform rules.
Email + SMS providers
Klaviyo, Mailchimp, ActiveCampaign, and most major ESPs prohibit restricted-product categories including peptides. SMS providers (Twilio, others) have more permissive rules but still flag certain compounds.
How brands navigate all three layers
Federal compliance
Position correctly (research vs supplement vs drug vs cosmetic — pick one explicitly), disclose properly, and don't make claims you can't substantiate. Work with a regulatory attorney for any product positioning that's close to the line.
State compliance
Geofence shipping to states where your product positioning holds up. Most brands ship US-wide and accept the jurisdictional risk; some brands explicitly exclude California, New York, or other strict-enforcement states.
Platform compliance
Operate within platform rules rigorously, build backup infrastructure for when accounts get suspended anyway, and don't depend on any single platform for survival. The platforms have no obligation to keep you on their services, so plan for losing each of them periodically.
What changes most often
All three layers shift, but at different paces:
- Federal: slow — FDA and FTC rules update over months/years, not weeks.
- State: moderate — individual states pass new laws each legislative session that can affect the category.
- Platform: fast — Meta, Stripe, Shopify can update their internal policies overnight without public notice. Most operational headaches come from this layer.
Operating in the peptide category in 2026 means continuously tracking all three layers. Brands that treat compliance as a one-time setup get caught by the second or third platform change. Brands that treat it as ongoing operational hygiene survive long-term.
