1. Set up the business
Form an entity, get an EIN and open a business bank account in the entity's name. Payment processors and suppliers check that your legal name, bank account and website all match, so set these up before you apply for anything.
2. Get legal advice on your products
This is the step founders skip and regret. How your products are classified affects what you can say, how you label them, where you can ship and which processors will work with you. A licensed attorney can review your catalog, labels and site copy. A research-use disclaimer on its own doesn't make a product or a sales model lawful.
3. Choose suppliers and arrange testing
Shortlist wholesalers, verify who they are and how they document quality, and order samples before committing to inventory. Arrange third-party testing so every batch has a certificate of analysis you can publish. Our supplier due-diligence scorecard walks through what to check.
4. Build the brand
A clear name, a consistent label system and a store that looks like a real company all affect conversion and processor reviews. Labels should accurately reflect contents, batch and intended use, as reviewed by your attorney.
5. Build the website
You need fast product pages, a COA library searchable by lot number, real shipping, refund, privacy and terms pages, and visible contact details. You can build on WooCommerce or custom. See how we build peptide websites.
6. Get payment processing
Apply with processors that underwrite stores in your category, and describe your products and business accurately. Test a real charge and refund before launch, set up chargeback alerts, and line up a backup. More in peptide payment processing.
7. Set up fulfillment
Shipping yourself keeps costs low early on. A 3PL frees up your time as volume grows. Either way, make sure tracking numbers sync back to your store and go out to customers automatically.
8. Install tracking
Set up analytics and confirm purchases are recorded. Add your site to Google Search Console and Bing Webmaster Tools and submit your sitemap so you can be found in search and AI answers.
9. Set up email and SMS
Repeat customers are where most stores make their money. Set up a welcome series, abandoned cart, post-purchase and win-back flows, and register your SMS number before texting. See email and SMS for peptide brands.
10. Launch and watch closely
Place full test orders on desktop and phone, check every form and email, then watch payments, orders and support messages closely for the first week. The full list is in our launch checklist.
Frequently asked questions
How long does it take to start a peptide business?
With suppliers chosen and a done-for-you team, the website and marketing setup can be live in about 2 weeks. Business formation, legal review and payment processor approval can add time, and processor timelines vary.
Do I need a lawyer to start a peptide business?
You should talk to a licensed attorney about how your specific products are classified, how they can be labeled and marketed, and where you can ship. A website disclaimer alone doesn't make a product or sales model lawful.
Can a peptide store accept credit cards?
Some processors underwrite stores in this category, and many mainstream platforms don't. Approval depends on your products, business and application. Apply accurately, and have a backup option.
Should I use white label peptides?
White label lets products ship under your brand. Some founders start by reselling a wholesaler's branded products and move to their own label once sales are steady.
What is a COA and why does it matter?
A certificate of analysis is a lab report showing what a batch tested as. Publishing a COA for every batch, ideally searchable by lot number, is one of the strongest trust signals a store can have.
