What It Actually Costs to Start a Peptide Business

Every budget you find online for this is either a $2,000 fantasy that ends in a frozen merchant account or a $250,000 number designed to sell you something. Here is the actual line-item cost of standing up a peptide business that survives month three, with the ranges we see across builds.

legal and entity: $3,000 to $9,000

• —Entity formation, registered agent, EIN, state registrations: $500 to $1,500.
• —Healthcare regulatory attorney review of 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 language: usually bundled into the above.
• —Product liability insurance: $1,500 to $6,000 annually, often paid monthly.

This is the line people cut and the one that costs the most to cut. The attorney is not reviewing a template, they are reviewing your live copy, because intended use is judged on your whole presentation. A clinical-lane business with an MSO structure sits at the top of this range or above it, since the entity design work is more involved.

sourcing and inventory: $8,000 to $25,000

Landed cost per vial runs $8 to $22 depending on compound, purity spec, and volume. MOQs typically sit at 500 to 2,000 vials per SKU, and lead times run 3 to 8 weeks. A focused launch of four to six SKUs therefore lands in the $8,000 to $25,000 range for first inventory.

• —Independent third-party lab testing of samples before you commit: $200 to $600 per compound. Non-negotiable.
• —Private label packaging, labels, cartons, and lot coding: $1,500 to $6,000 for a first run.
• —Ongoing per-lot COA testing: budget $150 to $400 per lot as a permanent operating cost.

Do not over-SKU at launch. Six SKUs with deep stock beats fifteen with none, because stockouts kill ad momentum and ad momentum is expensive to rebuild.

payment processing: $2,000 to $8,000 effective

Setup fees for a high-risk merchant account run $300 to $1,500. The bigger number is the rolling reserve: 5 to 10 percent of processed volume held for 180 days. At $100,000 a month in sales with an 8 percent reserve, that is roughly $48,000 of your own cash sitting in escrow at steady state. It comes back, but it is working capital you do not have while you are growing.

• —Gateway and monthly fees: $50 to $200 per month.
• —Discount rate 3.5 to 5.5 percent plus 25 to 35 cents, versus 2.9 percent on a mainstream gateway. On $1M annual revenue that is $15,000 to $25,000 of incremental cost.
• —Chargeback fees: $25 to $50 each. Keep the rate under 0.9 percent or the economics deteriorate fast.
• —Second processor setup: budget it. Redundancy is cheaper than a shutdown.

store build: $3,000 to $15,000

A templated Shopify build with a high-risk gateway integration, COA hosting, subscription app, and proper tracking sits at $3,000 to $6,000. A custom build with a real funnel, quiz or intake, and bespoke design runs $8,000 to $15,000. Ongoing software (subscriptions app, email platform, reviews, analytics) adds $200 to $600 per month.

Where the money should go: COA presentation, bundle logic, and checkout speed. Where it should not go: animations.

creative and content: $2,000 to $8,000

You need volume, not polish. A launch package of 15 to 25 creative assets across static, UGC-style video, and founder or provider-to-camera runs $2,000 to $8,000 depending on whether you shoot in-house. Then budget $1,500 to $5,000 per month ongoing, because creative fatigue is the primary reason a scaling account stalls.

fulfillment: $1,000 to $4,000 to onboard

3PL onboarding, packaging design and first run, and inbound freight typically total $1,000 to $4,000. Per-order costs land at $3 to $6 pick and pack plus postage, so $6 to $11 all-in domestic ground. Cold chain packouts where required add $4 to $9 per order. Build that into your pricing before launch, not after your first month of shipping.

first month of ad spend: $10,000 to $15,000

This is the number most people underestimate. Below roughly $10,000 in a first month you do not generate enough conversion events for Meta to optimize, so you spend the money and learn nothing. Plan $10,000 to $15,000 as a learning budget, expect the first two weeks to be inefficient, and judge the channel on week three and four.

For context on what the channel returns when it works: WayyLess put $4.3M through Meta and produced $19.1M at 4.45 blended ROAS. AC-NEXTGEN top creatives ran 7.5 to 16 ROAS, with one ad returning $53,269 on $6,049. Those results come after the learning budget, not instead of it.

the total, three scenarios

1. 1.Lean RUO launch: $30,000 to $40,000. Four SKUs, templated store, in-house creative, $10,000 ad budget. Viable if you are operationally hands-on.
2. 2.Standard launch: $45,000 to $60,000. Six SKUs, custom store and funnel, professional creative, $15,000 ad budget, proper legal review.
3. 3.Med spa adding an online channel: $20,000 to $35,000. You already own the prescriber, the patient base, and the credibility, so you are buying the ecommerce layer, processing, creative, and acquisition budget only.

the ongoing costs people forget

• —Reserve growth. As volume grows, more cash gets locked up. Model it monthly.
• —Per-lot testing, forever.
• —Creative production, forever. This is not a one-time cost.
• —Support staffing. This category generates more inbound questions per order than almost any other.
• —Legal re-review every time you add a SKU or change your claims.
• —Inventory carrying cost at 6 to 10 weeks of cover, which for a growing brand means constantly reinvesting cash into stock.

the businesses that fail here are rarely undercapitalized on inventory. they are undercapitalized on the three months where reserve, restock, and ad spend all come due at once.

None of this is legal, medical, or financial advice. Costs vary by market, product, and lane. Have an attorney and an accountant look at your specific plan before you commit capital.
