High-Risk Credit Card Processing for Peptides and Research Chemicals

Why peptides are flagged as high-risk

Peptides sit in a regulatory gray zone: not FDA-approved for human consumption, sold "for research use only," and increasingly under FDA enforcement focus. Card networks don't have a clean MCC for the category, so files get placed under MCC 5122 (drugs/pharmacy) or 5499 (misc food) with high-risk underwriting. Add a continuity billing model and the dispute exposure compounds.

What FDA and FTC scrutiny means for your processor

Acquirers monitor FDA warning letters and FTC enforcement against supplement and peptide brands. A warning letter in your name will get the MID frozen pending review. The protective structure most established peptide sellers use:

• Clear "for research use only" labeling on every product page
• No human-dosage instructions anywhere on the site
• No therapeutic claims (anti-aging, fat loss, muscle gain) tied to product names
• Age 21+ gating at checkout
• Terms requiring buyer attestation of research use

Underwriting requirements

• Corporate structure (LLC or corp, not sole prop)
• Business bank account at least 90 days old
• 3–6 months of processing history if available
• Website live with full T&Cs, refund policy, contact info, business address
• Product sourcing documentation (COA from supplier)
• Personal guarantee from owner(s) over 25% equity

Pricing and terms

Peptide rates land in 4.95%–7.45% + $0.30. Rolling reserve: 10–15% held 180 days. Setup typically $0–$495. Most acquirers cap individual transactions at $500–$1,500 until processing history is established. Monthly volume caps start at $25K–$50K and step up after 90 days of clean processing.

Chargeback control in peptides

Peptide disputes cluster around: shipping delays, product not received, and "I didn't authorize this charge" on continuity bills. The fixes:

• Tracking number on every order, with proactive shipping notification
• Clear refund policy honored without friction
• Pre-rebill email 3 days before continuity charge
• Verifi RDR + Ethoca alerts
• Descriptor with phone number

Why Stripe and PayPal don't work

Both explicitly prohibit "research chemicals" and unapproved drugs. Stripe will freeze on detection and hold funds 90–180 days. PayPal is the same. Self-aggregator routes (Square, Shopify Payments) are also dead-ends.

Approval path

Pre-qualify with website URL, monthly volume, and processing history. We'll tell you within 24–48 hours whether the file will approve and at what terms. Underwriting itself runs 5–10 business days after a complete submission.
