How to Start a Peptide Business From Scratch

A peptide business is buildable in two weeks if you sequence it right and takes four months if you do not. The difference is almost entirely about starting the slow items first. Here is the build, in order, with what each piece actually costs.

step 1: pick your lane before anything else

Research-use-only or clinical. RUO means you sell laboratory reagents to research buyers with no human-use claims, no dosing content, and no therapeutic marketing anywhere in your funnel. Clinical means a licensed prescriber evaluates patients and a 503A compounding pharmacy fills patient-specific prescriptions. The lane determines your entity structure, your processor application, your creative, your labeling, and your fulfillment. There is no version of this where you decide later.

If you already run a med spa, the clinical lane is usually the obvious choice, because you already own the expensive part: a licensed prescriber and an existing patient base. If you do not, RUO is the lower-barrier entry, with the tradeoff that your marketing is far more constrained and your compliance discipline has to be perfect.

step 2: entity and legal

For RUO, a standard LLC works. For clinical, most states impose corporate practice of medicine restrictions, meaning the clinical entity must be owned by licensed providers, with a separate management services organization handling marketing, technology, and administration under a management services agreement. Get this structure right at the start; unwinding it later is expensive.

• —LLC or PC formation and registered agent: $500 to $1,500.
• —Healthcare regulatory attorney review of your business model, labeling, and live site copy: $2,500 to $7,500 for an initial engagement.
• —Terms of sale, privacy policy, refund policy, buyer attestation or patient consent: usually included in the above.
• —Product liability insurance: $1,500 to $6,000 per year depending on volume and product mix.

The attorney line item is the one people cut. It is the wrong one to cut. A single letter from a state board or a federal agency costs more than a decade of legal review.

step 3: apply for payment processing immediately

This has the longest lead time, typically 5 to 15 business days, and it is a hard gate. Mainstream processors prohibit the category, so you need a high-risk merchant account. Underwriters want a live site with policies, clear refunds, real contact information, and published COAs before they approve. Build enough of the site to submit a credible application in week one, even if the store is not fully merchandised.

Budget 3.5 to 5.5 percent plus 25 to 35 cents per transaction, a 5 to 10 percent rolling reserve held 180 days, and $300 to $1,500 in setup fees depending on the acquirer. Get a second processor approved in parallel.

step 4: sourcing and private label

Your manufacturer decision determines your margin, your quality story, and your ability to scale. What to demand before you place a purchase order:

1. 1.Lot-specific COAs with HPLC purity and mass spectrometry identity. Purity above 98 percent as the floor.
2. 2.Independent verification: send your own samples to a third-party lab. Do not accept manufacturer results alone.
3. 3.Documented facility standards, sterile fill practices, and endotoxin testing where applicable.
4. 4.Lead time and MOQ in writing. Typical lead times run 3 to 8 weeks; typical MOQs run 500 to 2,000 vials per SKU.
5. 5.Private label capability: your labeling, your cartons, your lot coding, so the brand is yours and not a dropship storefront.
6. 6.A second qualified supplier before you need one. Supply interruptions in this category are common.

Expect landed cost of $8 to $22 per vial depending on compound and volume. Initial inventory for a focused 4 to 6 SKU launch typically runs $8,000 to $25,000.

step 5: build the store and the trust layer

The store is the cheapest part of this build and the one people over-invest in visually and under-invest in structurally. What matters: price per milligram visible, purity stated, lot COA linked from the product page, bundles that lift AOV above your CAC, a subscription option, and checkout that does not surprise anyone with shipping cost. Budget $3,000 to $15,000 depending on whether you are templating or building custom.

step 6: fulfillment

Pick a 3PL that already handles regulated or temperature-sensitive goods. Requirements: lot-level tracking, validated cold chain packouts if any of your SKUs need them, same-day or next-day cutoff, and packaging that survives transit without vial breakage. Expect $3 to $6 pick and pack plus postage, landing you at $6 to $11 per order all-in for domestic ground.

step 7: turn on traffic

Meta first. Google restricts most of this category and TikTok is stricter. Structure a simple account: one broad prospecting campaign with consolidated budget, one retargeting campaign, and a steady creative pipeline. The single biggest predictor of success is how many new creative concepts you can put into the market each week. Our accounts routinely have hundreds of live ads during scale phases, because the search for a winner is a volume problem.

On compliance: no personal attributes language, no implied diagnosis, no before-and-after imagery, no specific outcome promises. Educational, credibility-led, and process-led creative works and stays inside policy. AC-NEXTGEN top creatives run 7.5 to 16 ROAS inside those constraints.

what the whole thing costs to stand up

• —Legal and entity: $3,000 to $9,000
• —Store build: $3,000 to $15,000
• —Initial inventory: $8,000 to $25,000
• —Processor setup and reserve exposure: $2,000 to $8,000 effective
• —Creative production: $2,000 to $8,000
• —First month of ad spend: $10,000 to $15,000
• —Insurance, 3PL onboarding, software: $2,000 to $5,000

Realistic all-in range: $30,000 to $75,000 to launch properly. Med spas already holding a prescriber, patient base, and physical location can start meaningfully lighter because the clinical infrastructure is already sunk cost.

the first 90 days

1. 1.Days 1 to 14: build and launch. Processor submitted day one, attorney engaged day one, everything else in parallel.
2. 2.Days 15 to 30: validate unit economics on a controlled budget. Watch contribution margin, not just ROAS. Confirm delivery times and chargeback rate.
3. 3.Days 31 to 60: scale what works, add creative volume, get the email flows converting, launch the subscription offer.
4. 4.Days 61 to 90: add SKUs based on reorder data, open a second processor, build the retention program, and start organic content that will matter in month six.

nobody fails at this because their branding was wrong. they fail because processing froze, supply slipped, or the claims on their site did not match the lane they said they were in.

None of this is legal or medical advice. Peptide regulation is active and specific compounds move in and out of scrutiny. Engage a healthcare regulatory attorney before you sell, and re-review whenever you add a SKU.
