The #1 payment processing partner for high-volume RUO peptide brands.
Peptide operators told us the same thing all year: stability matters more than the lowest rate. So we build processing that stays on. Two or more fully underwritten accounts across separate acquirers, backup rails, and every term in writing before you sign.
We mark up your site the way an underwriter will and send it back within 1 business day. No card numbers. No obligation. Frozen right now? Call +1 (310) 293-2000.
All accounts are subject to underwriting by the processor and its sponsor bank. Approval is not guaranteed.
We read a year of peptide merchant posts. This is what goes wrong.
Thirteen peptide, CBD and supplement merchants posting publicly between October 2025 and October 2026. Their words, not ours, and none of them are our clients.

What would one shutdown cost you?
Simple arithmetic on your own numbers.
Simple math on your inputs: sales divided by 30.4 days, times days offline. Reserve figure assumes your percent held across a 6-month rolling window. Your real terms depend on your processor.

The Viking Redundancy Build
When one account gets reviewed, frozen or closed, your sales keep running on the next one, and you already know your terms because you have them in writing.
- 3.1
Underwriter Red-Pen Review
Before anything is submitted, we mark up your site the way a peptide underwriter will: dosing language, calculators, bundles, benefit claims, labeling. You get a fix list.
- 3.2
One file, the right doors
Your file is packaged once and submitted only to processors that knowingly board research peptides. No ten applications. No cold declines.
- 3.3
Primary and backup accounts
Two or more fully underwritten merchant accounts across more than one acquirer, each disclosed and sized to your real volume.
- 3.4
Volume allocation plan
Sales split across approved accounts by each account’s cap and approval rate, so no single account carries a spike. Never used to hide disputes.
- 3.5
Every term in writing
Reserves, caps, fees, settlement and termination terms side by side before you sign, with the clauses that hurt marked in plain English.
- 3.6
Chargeback control
Dispute alerts, 3DS, a descriptor your buyers recognize, and a monthly check against card network dispute thresholds.
- 3.7
Backup rails
ACH and eCheck where the bank accepts your category, set up in advance as a fallback, not a scramble.
- 3.8
Reserve reviews at day 90 and 180
On a calendar, we ask your processor to lower or shorten your reserve as clean history builds. Asked for, not promised.
- 3.9
A named specialist
One person with a direct line who knows your account and picks up on the bad day.
An approval is worth nothing if your customers' cards still decline.
One peptide merchant told a forum most of their card payments were failing even with a processor in place. Before you send traffic, we check that customers can actually pay.
| Descriptor | Matches your store name, with a support phone, so buyers recognize the charge. |
| Test transactions | Run on every card brand before you send traffic. |
| Decline review | If approvals dip, we pull the decline codes with you, not a ticket queue. |
| First settlement | We confirm the first deposit lands where and when the contract says. |
We cannot promise what a bank decides. We can promise what we do.
- 5.1
A straight answer in 1 business day
Your Red-Pen Review and an honest read on fit, within 1 business day of a complete form.
- 5.2
Every term in writing first
You see every reserve, cap, term and fee in writing before you sign. If we ever put something in front of you that we did not show you first, walk away.
- 5.3
The frozen-day callback
If an account we placed is frozen or under review, your specialist picks up or calls back within 2 business hours.
- 5.4
No lock-in
No contract with Viking. No exclusivity.
These commitments cover Viking's own service. Approval, pricing and reserves are decided by the processor and its sponsor bank and are not guaranteed.
One person owns your file from the first call.
| Day 0 | Tell us where you are. Two minutes: volume, processor, chargebacks, your site. Shut down today? You go to the front of the line. |
| Day 1 | Your written plan. Red-Pen Review, which processors fit, what they will ask for, what to fix first. |
| Then | Documents once. We package your file for each processor that fits and send a status update every week until you have answers. |
| Live | Live and covered. Accounts on, volume plan set, alerts on. Then a ratio report every month and a review every quarter. |
Who we work with, and who we turn away.
| We work with | We turn away |

| RUO peptide and research compound brands doing $250K+ a month, or growing fast toward it | Anyone marketing RUO products for human use, with dosing guidance or health claims |

| Founders who want a backup in place before they need it | Anyone trying to reopen under a new name after a termination |

Can you guarantee approval?
No one honest can. Approval is decided by the processor and its sponsor bank. What we commit to is our own conduct: a straight answer in 1 business day, every term in writing before you sign, and a fast callback when something goes wrong.
Why not just go with the lowest rate?
Because the rate is not what costs peptide brands money. A shutdown, a frozen balance or a reserve you did not understand costs far more. We still negotiate cost, but stability comes first, and so does knowing your terms.
Will I need a reserve?
Most peptide approvals carry one. You will see the percent, the cap and the window in writing before you sign, and we ask for reductions at day 90 and day 180 as your history builds.
I am processing fine today. Why talk to you?
Because a backup is built before you need it. Most brands add Viking as the second account first, so a shutdown on the main account costs hours, not months.
I was just shut down, or my funds are frozen.
Call the direct line. We can usually start a new application while you work on the hold. We never help anyone hide a past termination: that is how accounts close again, for good.
Who do you turn away?
Anyone marketing RUO products for human use, with dosing guidance or health claims, and anyone who wants a bank kept in the dark about what they sell. We get you approved by presenting your business honestly, because that is the approval that lasts.
