Math: one-time total = sum of one-time lines. First 3 months = one-time total + (monthly total × 3). Payment processing fees are a percentage of sales and aren't included.
Where founders overspend
- Too many products at launch. Every product adds inventory and testing cost. Start with your strongest few.
- Rebuilding the website twice. A cheap template that can't handle COAs, payments or affiliates usually gets rebuilt within months.
- Skipping legal review. It feels like a saving until a processor, ad platform or regulator flags your copy.
Where founders underspend
- Testing. Publishing a COA for every batch builds trust and repeat orders.
- Email and SMS. Repeat customers drive most revenue, and flows keep working after setup.

Frequently asked questions
What is the biggest cost when starting a peptide business?
For most founders it's initial inventory and third-party testing, followed by the website and legal review. The mix depends on your catalog size and how many batches you test.
How much does a peptide website cost?
It depends on the platform, catalog size and features. PepFounders quotes every build on a free call based on the services you need, on WooCommerce or custom Next.js.
Are payment processing fees part of startup costs?
Not usually. Processing fees are a percentage of each sale plus any account fees, so they scale with revenue. Ask each processor for their full fee schedule.
Can I start a peptide business with a small budget?
You can lower costs with a smaller opening catalog, reselling a wholesaler's branded products before switching to white label, and shipping orders yourself instead of using a 3PL.
