Who should build your peptide store? Every real option, priced.

Here is something you should know before you read any "best ecommerce platform for peptides" article, including this one: every single one of them is written by a company that sells one of the options. The platform guides rank the platform first. The agency guides conclude you need an agency. The payment processors publish platform roundups as a wedge into selling you processing.

This one is no different in one respect: I run pep.app, and pep.app appears in the comparison below. It is different in two others. Every price in this guide comes from the provider's own public pages, pulled in August 2026, so you can check my work. And there is a section at the end on when pep.app is the wrong choice, because in a category where sellers get burned by their own infrastructure this often, the fastest way to lose your trust is to pretend we fit everyone.

The four ways this actually gets built

Strip away the branding and there are four paths. Each one is right for somebody.

• DIY WooCommerce. You install WordPress, WooCommerce, and a stack of plugins yourself. Cheapest possible entry, and you own everything. You also own everything: payments, compliance gating, COA display, state blocking, uptime, and every plugin conflict at 11pm before a launch.
• A freelancer. Fiverr lists two dozen peptide-store gigs under $1,000. You get a themed WooCommerce install. What you do not get is high-risk payments, compliance architecture, or anyone who answers in month three.
• A specialist agency. A real studio that has built peptide stores before designs and ships yours, usually on WooCommerce, in 6 to 14 weeks. You own the result, and you also own operating it, which is why most agencies attach a monthly care plan.
• A managed platform. The store runs on the provider's infrastructure for a monthly fee. The build is faster and operations are included; the trade is that you are betting on the platform's competence and its survival.

What everything costs, verified August 2026

Published pricing, from each provider's own site, on the date I checked. Quote-based providers are marked. If you are reading this later, verify before deciding; this market moves.

Two things in that table deserve a closer look. Swell's overage fees are a revenue share with a different name: cross your plan's sales ceiling and the platform takes 0.4 to 2 percent of the excess. And PeptideSetup's entry tier is, to the dollar, the same $699 a month as ours, which means price will not make this decision for you. The next section is what will.

The seven questions that actually sort providers

Feature lists in this category converge. These questions do not.

• Who owns the merchant account? If the answer is "you'll sort out payments separately," the hardest problem in peptide commerce just became your problem. Ask whether the provider gets you underwritten, or just leaves a gateway field empty.
• What happens when a processor drops you? Not if. Ask whether a second processing path exists before you need it, and who does the failover.
• Is COA and lot infrastructure native or a plugin? Per-lot certificates with automatic rotation is table stakes for serious buyers and for underwriters. A PDF upload field is not the same thing.
• Who maintains the state-restriction logic? Restricted-state lists change. Someone has to watch them and ship the update. If that someone is you, price your time in.
• Is there a revenue share hiding anywhere? Overage percentages, payment markups, "success fees." Flat is flat; read the pricing page like an underwriter reads your application.
• What proof exists? Named clients you can visit and verify beat portfolio screenshots, which beat claims with no names attached. Apply that test to everyone, including us.
• What happens after launch? An agency hands you keys. A platform runs the store. Neither is wrong, but one of them assumes you want a second job in ecommerce operations.

The anonymity trap

Some providers in this space sell offshore hosting, hidden WHOIS, and crypto-first checkout as features. I understand the instinct, and if your plan is to operate outside the rules, no website vendor can help you anyway.

But if you are trying to build a durable, bankable business, understand what that pitch costs you. High-risk underwriters review your storefront, your corporate records, and your operational transparency before they approve you. An anonymized domain on offshore infrastructure with monero at checkout reads, to the person deciding your merchant application, exactly like what it is designed to read like: a merchant planning to be hard to find. The infrastructure sold as protection from scrutiny is a liability in front of the only scrutiny that decides whether you can take card payments.

Anonymity and underwriting are opposite strategies. Pick deliberately, because you cannot run both.

What's under the hood matters more than the theme

Almost every specialist agency in the table ships the same architecture: WordPress, WooCommerce, and a stack of third-party plugins for age gates, COA files, and disclaimers, on rented hosting. It works. It is also a machine with a dozen vendors inside it, and you are the integrator of record when two of them disagree after an update.

We made a different bet and built the platform as one system. What that means concretely, since "modern stack" is a claim anyone can type: the storefront and checkout run on a current application framework with custom cart and checkout APIs rather than plugin chains; order, lot, and customer data live in a managed Postgres database; shipping runs through carrier APIs with the cold-chain rules built in; every error in the system is caught by production monitoring (we run Sentry) before a customer emails about it; and every store ships with built-in business analytics, with an AI layer on top of it, so "what actually sold last month and what's my reorder rate" is a dashboard, not a spreadsheet project. None of those line items is exotic in real software companies. In this category, they are rare enough to be a differentiator, which tells you something about the category.

The 24-month math

Launch cost is the wrong number; two years of ownership is the right one. Rounded, using the published prices above:

• Premium agency path: $15,000 build plus a $1,000–2,500/mo care plan and hosting runs roughly $39,000–76,000 over 24 months, and payments are still your project.
• Budget agency path: a $1,900–4,900 build looks cheap until you add maintenance you now have to source, and the same unsolved payments problem.
• Managed platform path: PeptideSetup's entry tier runs about $17,500 over 24 months; pep.app runs about $18,700 with the white-label setup. Within rounding of each other, which is why the seven questions above, not the invoice, are the real comparison.

Where pep.app lands, and when it's the wrong choice

You can guess our conclusion: for a founder who wants to sell research peptides legitimately and does not want to become a systems integrator, we think pep.app is the strongest option on the board, because it is the only one where the storefront, the payments path, the compliance architecture, and the post-launch growth tooling are one accountable system at a flat price. That is also exactly the conclusion you should expect this site to reach, which is why the table above shows real prices and the questions above work against every provider, including us.

And here is the honest inverse. pep.app is the wrong choice if you want full code ownership on day one (hire Beenacle or onPoint and budget accordingly); if your total budget is under $2,000 all-in (start DIY and upgrade when revenue justifies it); if you already employ developers and hold your own merchant account (a headless platform like Swell gives your team more surface); or if what you sell is not research peptides, because everything opinionated about our platform is opinionated for this category.

Competitor pricing and features were taken from each provider's public website in August 2026 and may have changed; verify directly before making decisions. pep.app is not affiliated with any provider named here, all trademarks belong to their owners, and this guide reflects our honest read of public information plus an obvious commercial interest we have tried to keep in plain sight. Not legal, financial, or payments advice.
