B2B Peptide Brand Merchant Account Approval: What Unison Reviews
Quick answer: Unison Payment Solutions is a payment processor — we do not sell peptides. We now underwrite qualified B2B peptide and RUO wholesale brands that need dedicated high-risk merchant accounts. Approval depends on research-use-only website positioning, published policies, chargeback history, fulfillment documentation, and acquirer fit — not a generic Stripe signup. Prepared B2B files typically move through underwriting in 3–7 business days; merchant account approval rates for complete applications exceed 80% in our peptide pipeline (separate from gateway authorization rates).
If you operate a wholesale research-supply brand, you already know payment processing is harder than fulfillment. Mainstream processors auto-decline “peptide” keywords. Aggregators approve you briefly, then freeze funds when chargebacks spike or compliance scans flag product copy. B2B adds another layer: larger tickets, repeat buyers, mixed card and ACH volume, and underwriters who do not distinguish legitimate research supply from consumer wellness marketing.
This guide explains what Unison reviews for B2B peptide merchant account approval, how it differs from DTC RUO stores, and where to start if you were shut down by Stripe, Square, PayPal, or Shopify Payments.
Unison Is Your Processor — Not Your Supplier
Before anything else: Unison Payment Solutions provides merchant accounts, gateways, and processing support. We do not manufacture, warehouse, or sell research compounds. Products sold by our merchants must be positioned by those merchants for research use only — not for human or veterinary consumption and not for diagnostic or therapeutic use.
That boundary matters for underwriting. Banks evaluate your website, policies, descriptors, and chargeback behavior — not product efficacy claims. We do not provide dosing, medical, or personal-use guidance.
Who the B2B Program Fits
Strong fits:
- Wholesale RUO peptide suppliers with clear research-use disclaimers on product and checkout pages
- B2B distributors serving qualified organizations with documented fulfillment (inventory, 3PL, shipping SLAs)
- Established brands with processing history and chargeback ratios under acquirer thresholds
- Operators integrating WooCommerce, Shopify (third-party gateway), or custom carts with high-risk gateways
Poor fits:
- Sites with human-consumption, wellness, anti-aging, or disease-treatment language
- Businesses without refund, shipping, terms, and privacy policies
- Operators expecting guaranteed approval regardless of compliance gaps
- Catalogs that imply injectable personal use or medical outcomes

How B2B Underwriting Differs From DTC Peptide Stores
DTC RUO ecommerce and B2B wholesale share the same high-risk category, but underwriters weigh different signals:
| Factor | DTC RUO store | B2B wholesale |
|---|---|---|
| Average ticket | Often lower, higher velocity | Larger tickets, repeat buyers |
| Payment mix | Mostly card | Card + [ACH/eCheck](/blog/peptide-ach-echeck-setup) for standing orders |
| Chargeback type | Shipping delays, buyer remorse | Invoice disputes, delivery timing on bulk orders |
| Compliance focus | Product page claims, checkout disclaimers | Same — plus wholesale terms and buyer communication |
Both models require research-use positioning. B2B is not a loophole for human-use marketing. If your site reads like a supplement brand, expect declines regardless of buyer type.
The Underwriting Checklist We Use
When you request a B2B processing review, we audit payment-related compliance before bank submission:
1. Research-use disclaimers on product pages, cart, and checkout 2. Policies published: terms, privacy, refund, shipping, contact 3. Billing descriptor alignment with your brand (reduces “did not recognize” disputes) 4. Business documentation: formation, EIN, owner ID, voided check 5. Processing history: prior statements, chargeback ratios, shutdown letters if recovering 6. Fulfillment proof: inventory, supplier agreements, 3PL contracts, realistic shipping SLAs 7. Documentation practices: where your catalog references COAs or batch records, underwriters may review how you present documentation — we do not validate product purity claims
> Prepared applications with complete files exceed 80% merchant account approval in our peptide pipeline. Gateway authorization rates are a separate metric and often reach 96%+ when descriptors, AVS/CVV rules, and issuer patterns are configured correctly.
Card Processing vs. ACH for B2B Peptide Brands
Many wholesale brands push repeat domestic buyers to ACH for lower fees and fewer chargeback exposures, while keeping card checkout for first orders or international buyers where approved.
Unison helps structure both rails where underwriting allows. ACH does not eliminate compliance requirements — your site positioning must still be research-use-only — but it can stabilize account health when chargeback risk is concentrated on card volume.
Rates, Reserves, and What We Will Not Quote Blindly
B2B high-risk processing uses interchange-plus pricing: wholesale interchange and assessments plus a disclosed markup. Exact rates depend on volume, ticket size, chargeback history, and acquirer appetite.
Rolling reserves (often 5–10% held 90–180 days) are common for newer high-risk accounts. We disclose reserve terms before boarding — unusually high demands without explanation are a red flag we walk you through.
We do not publish guaranteed rates or guaranteed approval online. If a processor promises both without reviewing your file, treat that as a sales tactic, not underwriting.
Recovery After a Processor Shutdown
If Stripe, Square, PayPal, or Shopify Payments terminated your B2B peptide account:
1. Stop processing on backup aggregators that prohibit your category — that extends MATCH exposure 2. Fix compliance copy before reapplying anywhere (remove human-use implications) 3. Gather shutdown letters and processing statements for the next underwriting file 4. Request a pre-submission review — our peptide processing apply flow and RUO LP start here
