This comparison looks only at the peptide category. For a general store, read the broader WooCommerce vs Shopify comparison. Nothing here is legal advice, and platform policies were checked on 9 November 2026.
Is WooCommerce or Shopify better for a peptide store?
WooCommerce is generally the safer choice for a peptide store, because it is self-hosted and no platform provider can remove the store itself. Shopify offers easier operations, but a store depends on a company whose terms it does not control. The trade-off is responsibility: on WooCommerce, the owner takes on hosting, security, updates and backups, and payments remain unsolved on both.
| Factor | WooCommerce | Shopify |
|---|---|---|
| Who can take the store down | Your host, or a legal order | Shopify, under its terms |
| Software cost | Core plugin is free | Monthly subscription |
| First-party payments for peptides | WooPayments lists peptides as prohibited | Depends on underlying processor, confirm in writing |
| Third-party gateway surcharge | None from WooCommerce | 2%, 1%, 0.6% or 0.2% by plan |
| Maintenance | Owner's responsibility | Handled by Shopify |
| Custom COA and catalogue logic | Fully customisable in code | Possible through theme and apps |
| Data portability | Your own database | Export tools |
Does Shopify allow peptide stores?
Shopify's public policies do not give a clear yes. Its acceptable use policy did not name peptides when checked, and its Shop channel separately prohibits drugs and medication. Agency and vendor blogs report peptide stores being shut down, though that could not be confirmed against Shopify's own wording. Treat eligibility as unconfirmed, and ask Shopify directly in writing before you build.
The Shop channel's prohibited products page applies to that sales channel rather than to all of Shopify, but it shows how the company views the wider category. The practical risk is losing the storefront, customer access and sales momentum at the same time.
Does WooCommerce remove the compliance risk?
No. WooCommerce removes dependence on a hosted platform, but regulators, payment providers, banks and hosts still apply their own rules. FDA warning letters assess what a website says and sells, whatever software runs it. A self-hosted store with careless claims carries the same legal exposure, so platform choice should come after legal advice and should not stand in for it.
How do payments differ between the two platforms?
On WooCommerce you can connect any compatible gateway your processor supports, and WooCommerce charges nothing per transaction. On Shopify, a third-party provider attracts an added fee of 0.2% to 2% depending on plan, and the provider must be able to integrate with Shopify. Either way, the deciding factor is which processor accepts the business, which the payment guide covers.
Which platform handles certificates of analysis better?
WooCommerce handles certificates of analysis more flexibly, because a developer can store documents against a product or lot and control exactly how they appear. Shopify can display documents using metafields and theme customisation, which suits simpler needs. For a store with many lots changing frequently, the custom workflow that WooCommerce allows is usually worth having, and Canamino links documents by lot on the product page.
What does each platform cost a peptide store to run?
WooCommerce costs hosting, premium plugins and maintenance time, while its core software is free. Shopify costs a monthly plan, app subscriptions and any third-party gateway surcharge. On either platform, processor fees for a high-risk merchant account are likely to be the largest ongoing cost, so get those quoted before comparing platform costs, since they can outweigh every other line.
When would Shopify be right for a peptide-adjacent business?
Shopify can suit an adjacent business selling general lab supplies or equipment, once Shopify and its processor confirm eligibility in writing. It may also suit a team with no appetite for server maintenance, provided that approval exists. Without written confirmation, the convenience is not worth the risk of losing the store after launch. Akif Wani builds on both platforms and advises on this during scoping.
