The peptide problem, precisely
Peptides aren't categorically banned: semaglutide and tirzepatide are peptides, and dozens of FDA-approved drugs are peptide-based. The problem is the specific set of experimental peptides sold online for human use without any approved-drug pathway. LegitScript's own guidance names the usual suspects: Melanotan 2 (tanning), ipamorelin (muscle growth and recovery), tesamorelin (weight loss), CJC-1295 (performance), BPC-157 (injury recovery and anti-aging), thymosin beta-4 / TB-500 (muscle and injury recovery), and the GHRP family.
It gets sharper: the FDA has declared several of these (BPC-157, CJC-1295, and Melanotan II among them) impermissible for compounding due to safety concerns. That means even a licensed compounding pharmacy with a physician's order isn't a lawful path for them. A telehealth menu offering 'BPC-157 recovery protocols' isn't a disclosure problem; it's a catalog problem.
And the reach extends past your own site: LegitScript's application checklists list affiliations with sellers of unapproved drugs (impermissible peptides and bulk substances specifically) as a common certification barrier. If your platform, your pharmacy partner, or a co-owned brand sells them, your application inherits the problem.
Rule of thumb from the primary sources: if a peptide has no FDA-approved drug pathway and shows up in bodybuilding, tanning, or 'recovery stack' marketing, assume it's a certification barrier, on your site or your affiliates'.
“Research use only” makes you look worse
The most counterintuitive finding in LegitScript's peptide guidance: merchants who prominently label products 'not for human consumption' or 'for research use only' are more likely, in LegitScript's experience, to be engaged in unapproved peptide sales. The disclaimer reads as an attempted legal shield, not a safeguard.
What actually distinguishes a legitimate research-chemical supplier: real safeguards against personal-use sales: verifying buyers are professional researchers, quote-based ordering instead of an open cart, institutional billing. A storefront with a Buy Now button, consumer pricing, and an RUO disclaimer is the exact profile the payments industry is trained to flag.
For telehealth operators the lesson is simpler: never let RUO-labeled products share a brand, a domain, or a corporate family with your prescription business. The association costs more than the SKUs earn.
The gray zone: compounded GLP-1s and 'in-demand' peptides
LegitScript's guidance singles out semaglutide and tirzepatide for special scrutiny: legitimate approved products exist, popular demand is enormous, and illegal sellers cluster around both facts. Post-shortage, compounded versions need a documented patient-specific clinical rationale (we cover that fully in the compounded-GLP-1 guide), and any site offering them should expect its sourcing, prescribing model, and claims to be read closely.
The practical sort: approved-pathway products prescribed through a real clinical model are certifiable; experimental peptides marketed for human use are not; and compounded versions of approved drugs live in between, certifiable exactly to the extent the clinical-need documentation is real.
How to audit your own catalog
Walk your Rx menu, your wellness menu, and your affiliates' menus, and sort every item into three buckets: approved pathway (an FDA-approved product or a defensible compounded formulation with documented clinical need), scrutiny tier (NAD+, HBOT, HRT; keep the claims modest), and barrier tier (the named peptides, hCG-for-weight-loss, stem cell/exosome, ozone, anything RUO-labeled). The barrier tier doesn't get better copy; it gets removed, or it blocks the application.
Our free Preflight scanner runs the product-lexicon pass automatically: it flags the named peptides, the barrier-tier offerings, and RUO language on any page it can crawl, alongside the claims and disclosure checks. It won't judge your clinical documentation (nothing automated honestly can), but it will tell you in a minute whether your public catalog has a barrier-tier problem.
Certification reviews are catalog-first: reviewers can waive a copy problem during review, but they can't waive what you sell. Sort the menu before you spend the $975.
Frequently asked
- Are all peptides a problem for LegitScript certification?
- No. FDA-approved peptide drugs (including GLP-1s) prescribed through a genuine clinical model are certifiable. The barrier is experimental peptides with no approved human-drug pathway sold for human use: BPC-157, TB-500, CJC-1295, Melanotan 2, ipamorelin, tesamorelin, and the GHRP family are the ones LegitScript names.
- We label those products 'research use only.' Doesn't that cover us?
- The opposite: LegitScript's guidance says RUO labeling on consumer-facing storefronts is a red flag that makes unapproved-sale activity more likely, not less. Legitimate research suppliers verify buyers and quote orders; a Buy Now button with an RUO disclaimer is the flagged profile.
- What if only our pharmacy partner or sister brand sells the problem products?
- The affiliates standard reaches them: LegitScript checklists list affiliations with impermissible-peptide or unapproved-drug sellers as a certification barrier, and a partner's compliance review can affect your certification.
- Is hCG really blocked for weight loss?
- hCG for weight loss appears on LegitScript's med-spa checklist as a common certification barrier (the FDA has long said hCG isn't approved for weight loss and required warning labels on the point). hCG has legitimate approved uses; weight loss isn't one of them.
