Payment processing for peptide stores moves money from a customer's card or bank account to your business account through 5 parties: the customer, your checkout, a payment gateway, an acquiring bank, and the customer's issuing bank. Authorization completes in under 2 seconds; settled funds reach your bank in 2 to 3 business days for cards and 1 to 3 days for ACH.
What are the 5 parties in a peptide payment transaction?
Every peptide card transaction passes through 5 specific parties in a fixed sequence. The customer enters card data into your checkout, the gateway tokenizes and forwards the transaction, the acquiring bank routes it through Visa or Mastercard, the issuing bank approves or declines, and the network returns the answer to your gateway. Misconfiguration at any single step is the most common reason peptide merchants see elevated decline rates.
How long does authorization take?
Authorization completes in 1.2 to 2 seconds on a healthy peptide checkout. Anything over 4 seconds signals a misconfigured 3D Secure step, an underprovisioned gateway, or a fraud screening rule that is doing a synchronous lookup it should be doing asynchronously. Run a synthetic checkout test weekly to catch latency regression before it costs you conversion.
How long does settlement take for peptide merchants?
| Payment method | Auth speed | Settlement to bank |
|---|---|---|
| Credit and debit cards | Under 2 sec | 2 to 3 business days |
| ACH bank transfer | 5 to 30 sec | 1 to 3 business days |
| Cryptocurrency (USDC) | 15 to 60 sec | Same day |
| BNPL | 3 to 8 sec | 1 to 2 business days |
High-risk peptide accounts often carry a rolling reserve hold of 5% to 10% on top of normal settlement timing.
Where do peptide merchants get bottlenecked?
Three bottlenecks account for most settled-funds delays. First, batch close: many peptide merchants forget to set a daily auto-close, which delays settlement by a full day. Second, mismatched descriptor: when the billing descriptor does not match your DBA, the issuer holds funds for fraud review. Third, reserve mechanics: new MIDs see 9% to 12% of every batch routed to reserve before the rest settles.
How does the issuing bank decide to approve or decline?
The issuing bank runs the transaction against the cardholder's available credit, the merchant's MCC, the cardholder's recent transaction pattern, and a 3D Secure liability check if enabled. Peptide MCC 5912 sees higher decline rates than mainstream MCCs because some issuers apply a velocity filter on first-time peptide purchases. Enable 3D Secure 2.0 to shift liability and unlock lower card-not-present interchange rates.
Frequently asked questions
Why does my settlement vary day to day?
Settlement varies with batch close time, payment method mix, and weekend cutoffs. Cards batched after 3pm ET on Friday settle the following Tuesday.
Can I speed up settlement on a peptide account?
Same-day funding is available on some peptide MIDs for a 0.5% per-transaction fee. The economics work above $250,000 monthly volume.
What is the most common cause of failed authorization?
AVS mismatch on the billing zip code, followed by CVV mismatch. Both are misconfigurations in the checkout form, not network issues.
