How to start a research peptide company: the complete checklist

Launching a research-peptide business is less about the products and more about the infrastructure around them — the entity, the bank account, the payment processing, and the compliance posture. Get those right and you're a real, durable business. Get them wrong and you'll get frozen by a processor or shut down by a platform within weeks.

This is the order of operations we'd follow today. Each step links to a deeper guide.

1. Validate the plan & pick your lane

Decide what you'll sell and to whom, and commit to a research-use-only (RUO) positioning from day one — products sold for laboratory and research purposes, not for human or animal consumption. This single decision shapes your labeling, marketing, legal pages, and payment-processor eligibility. Know your competitors, your margins, and your target customer (independent researchers, labs, resellers).

2. Form the business entity & get an EIN

Before you open a bank account or apply for payment processing, you need a legal entity (usually an LLC) and a federal EIN. Processors and banks underwrite a business, not a person. This is the foundation everything else sits on.

3. Open business banking

Open a dedicated business bank account so your business and personal finances never mix. Clean separation is essential for bookkeeping, taxes, and — critically — for passing payment-processor underwriting later.

4. Sort out payments early — it's the long pole

This is the step most founders underestimate. Mainstream processors (Stripe, PayPal, Shopify Payments) generally prohibit this category, so you'll need a high-risk merchant account, which takes underwriting and time. Start the application process in parallel with the rest of your setup, and plan backup manual rails (ACH, wire, etc.) so you're never stuck unable to take payment.

5. Build your compliance foundation

Compliance isn't a final step — it's a prerequisite that underwriters and platforms check before they'll work with you. At minimum you need: RUO labeling and "not for human consumption" disclaimers, a restricted-states policy, age verification, clear terms / privacy / refund policies, and a research-use acknowledgment at checkout.

6. Source product & get Certificates of Analysis

Work with reputable suppliers and obtain third-party Certificates of Analysis (COAs) — HPLC purity and mass-spec identity — for every batch. COAs are both a quality control and the single biggest trust signal you can show a customer. Track batches so each order can be tied to its COA.

7. Set up operations

Decide how you'll handle inventory, packaging, shipping (carriers, discreet packaging, restricted-state blocking), and returns. Even at small scale, a clear fulfillment process prevents the errors that generate chargebacks and complaints.

8. Build the storefront & go live

Your website needs to do more than look good: it must display COAs, gate the catalog behind a research-use acknowledgment, verify age, block restricted states, calculate tax, and hand payment to your own processor. This is exactly where most generic store builders fall short for this category — and where PEP Websites comes in.

9. Market & grow — compliantly

Drive traffic with SEO and content, build an email list, and consider an affiliate program. Keep all marketing claims compliant — no medical, therapeutic, or human-use claims. The fastest way to lose your processor is deceptive or non-compliant advertising.
