Peptides — research-use-only formulations, cosmetic peptides, longevity compounds — are a category Shopify Payments often restricts. Storefront works. Checkout does not. Own-domain checkout wires your peptide-friendly MID into Shopify without needing that gateway on Shopify's approved list, and cascades to a backup MID when the primary throttles.
Peptide operators often burn a Shopify Payments account after a review that flags the product mix or the marketing copy. What breaks is the payment method — the Shopify store itself is fine. Product catalog, cart, apps, discount codes, Klaviyo, fulfillment and marketing pixels all continue to work. Move the checkout URL and Shopify continues.

Second peptide-friendly MID as fallback. Cascade rotates on decline, timeout, throttle. Order writes back to Shopify tagged [cascade].
Legal status of peptides varies by specific compound, country, US state, prescription vs research-use classification, dosing and route of sale. Some peptides are prescription-only. Some are RUO. Some are prohibited entirely. You remain responsible for compliance, accurate RUO labeling and MCC disclosure in every jurisdiction you sell to. CascadeCheckout does not modify or hide your product category from your acquirer.
Peptides are a category Shopify Payments often restricts. The Shopify storefront usually works; the payment step is what fails. Own-domain checkout via CascadeCheckout wires a peptide-friendly MID you contracted with directly, without touching Shopify's approved list.
No. We do not underwrite or issue MIDs. You contract with your own peptide-friendly acquirer, offshore bank or high-risk gateway. We are the software layer that wires the MID you bring.

Depends on your underwriting, product mix and jurisdiction. Offshore acquirers, high-risk NMI resellers, custom-HTTP banking rails and specialist providers serve some peptide merchants. Approval is between you and the acquirer.
