How to Accept Payments for Peptides on WooCommerce (Legally, in 2026)
Peptides are one of the top three blocked verticals on Stripe. Here's a compliant path to taking cards on a peptide store — with Woopay routing through PayPal REST.
Why every mainstream gateway declines you
Stripe, Braintree, Adyen and Square all classify peptides as research chemicals and blanket-ban them. Traditional high-risk providers will onboard you, but at 4-6% + $0.30 per transaction with a 10% rolling reserve for 180 days.
Woopay is a middle path: PayPal's Advanced Card Processing REST API has separate underwriting and, for genuinely compliant peptide sellers labelling products as "for research use only," approvals are common.
The compliance checklist
Before you install Woopay, get your store legally clean:
- Every product page must display "For research use only. Not for human consumption." above the fold.
- No dosage instructions, no "how to inject" content, no bodybuilding claims.
- Ship only to jurisdictions where the specific peptide is legal to sell (US, most of the EU, UK — check each SKU).
- Age-gate the whole store to 21+.
- Publish a returns policy, a shipping policy, and a physical business address.
Installing Woopay
Once your store is compliant, install the plugin, paste your licence key, connect PayPal REST and enable Live mode. Run one sandbox transaction end to end.
What to expect long term
A well-run peptide store on Woopay averages 0.4% chargeback ratio — below PayPal's 0.9% threshold. Stay under that number and your account is stable indefinitely.
