Design + development · Research-use-only stores
Built by the team that runs live research-peptide stores every day - not a generalist agency learning the category on your invoice. Compliance enforced in the code. Payments that don't get shut off. A real person watching it every month.
The uncomfortable part first
A peptide store doesn't fail because it looks bad. It fails because three different reviewers read it - the FDA, a payment underwriter, and a platform's content scanner - and a designer who has never faced any of them writes copy that fails all three. The store they hand you works for a month or two. Then it doesn't.
The full pattern, with the 2026 enforcement wave: why peptide companies keep shutting down.
Intended use is inferred from the totality of your site - product copy, FAQ answers, blog posts, even image alt text. A conversion copywriter's "benefits" section is exactly the human-use signal the March 2026 warning-letter sweep punished, and an RUO banner next to it makes things worse, not better.
Stripe, Square, and PayPal all prohibit the category and run continuous content scans of merchant sites. A designer who wires up Stripe Checkout has built you a countdown: termination, then a 90-to-180-day hold on your money. We've written the recovery playbooks - Stripe, Square, PayPal - because operators arrive here after living them.
Build on Shopify or Wix and the platform itself is a second termination risk - a Shopify ban deletes your storefront and your checkout on the same day, and your theme, apps, and URL structure go with it. A designer renting you a platform that prohibits your products isn't selling you a website. They're selling you a liability with a nice theme.
The free 60-second audit reads your live store the way the FDA and a payment underwriter do and grades it A to F. If it's clean, you saved a call. If it isn't, you'll see exactly what's exposed - before a reviewer does.
Free site audit →What a Stonegate build includes
Every store ships on the same engine we run our own live builds on. The guardrails aren't a checklist someone has to remember - they're enforced by the platform on every page, every product, every email.
A do-not-list of prohibited compounds is enforced at product creation - even in your own admin. A flagged compound can't be listed, renamed, or slipped in later.
Human-use, dosing, and claim language is blocked before it can publish - product pages, blog posts, and every marketing email pass through the same check.
Age gate, qualified-researcher gate, and RUO labeling on every page - and every order carries a logged customer consent you can produce on request.
Multi-rail checkout built for processors that knowingly board this category, with backup rails wired in - so one decision can't freeze your revenue.
Orders, inventory, customers, finance, and reporting in one place. Manual orders, volume pricing, discounts, and shipping labels included - no third-party app stack.
Lot-level certificates of analysis attached to every product, managed from the admin - the trust signal serious buyers and underwriters both look for.
Designed around your brand from scratch. No two builds look alike, and none of them look like a recolored template.
Your domain, your database, your customer list - always exportable. No platform sitting between you and your own store, and no ban that can take it away.
How it works
Grade your current site in 60 seconds - or skip straight to the call if you're starting from zero.
30 minutes, free. We scope exactly what you need and you leave with a fixed price and a timeline - no obligation.
You send assets from one short checklist. We design, build, migrate your catalog and COAs, and wire the payment rails.
Live and taking payments. From day one, a real person reviews the store monthly and makes the fixes as the rules move.
Your store is live and taking payments within 14 days of your assets reaching us, or we work free until you are. "Assets in" is a specific checklist we hand you before you pay a cent - no moving goalposts.
Pricing
Custom builds start at $4,900, with your exact price fixed on the build call. Every store runs on a monthly plan from $300/mo - hosting, backups, and a human compliance review every month.
Custom design, full compliance engine, white-glove build.
+ monthly plan from $300/mo
Why own instead of rent? A template platform can price you out, change its rules, or ban the category outright - and every one of those decisions lands on your revenue. When you own the stack, the only party that can turn your store off is you. The math on renting is in our breakdown of peptide website builders.
FAQ
Custom builds start at $4,900. Your exact number depends on scope - product count, migrations, custom features - and you get it on the build call before you commit anything. Every build runs on a monthly plan from $300/mo, which is what keeps a real person on your store as the rules change.
14 days from assets-in, and we put it in writing: live and taking payments within 14 days of your assets reaching us, or we work free until you are. "Assets in" is a specific checklist we hand you up front, so the clock can't move on you.
Sometimes. Start with the free audit - it grades your live site the way the FDA and a payment underwriter read it. If the bones are good, we quote a cleanup. If the site is on a platform that bans the category, a cleanup just delays the same ending, and we'll tell you that straight on the call.
Constantly - it's the most common starting point. We rebuild on infrastructure you own, wire in payment rails built for the category, and fix the copy that got you flagged so the next underwriter reads a different site. What we won't do is help you sneak back onto a platform that terminated you - that's how operators end up on the MATCH list for five years.
Research-use-only compounds are sold lawfully by many businesses, but the line is drawn by how a site presents them - the FDA reads intended use from the totality of your site, not from any one disclaimer. We build stores to stay on the right side of that line and keep them there. We're not a law firm, nothing here is legal advice, and compound-level questions belong with counsel. If you're starting from scratch, read how to start a peptide company first.
All 50. The whole engagement is remote - audit, calls, intake, build, launch, and the monthly monitoring - so it works the same whether you're in Florida or Alaska.
You own your brand, domain, content, customers, and data - always exportable, never locked in. The store software, hosting, and monitoring are a managed service we run so you never have to touch code.
Because both platforms prohibit the category. A designer can make the store beautiful; they can't stop the platform's own content scans from reading it, and when the ban lands you lose the storefront and the payments on the same day. This category needs infrastructure you own and copy that passes a compliance read - not a nicer theme. More in the guides library.
Start with the free 60-second audit, or book a free 30-minute build call and leave with an exact price and timeline. Zero obligation either way.
