PepLab: A research-use-only reagent storefront with an age gate, multi-market logic and an external checkout hand-off.

The challenge

PepLab sells research-use-only reagents, so the site had to enforce a strict age gate and 'not for human or veterinary use' framing throughout while still feeling like a premium store.

It also needed to serve several markets with different availability, and build purchase trust without a heavy backend.

What we built

Compliance and age verification are mandatory. We added a prominent 21-plus age gate on entry and research-use-only disclaimers across headers, footers and product copy.

Checkout without a full backend. We routed each product to an external store checkout, with a WhatsApp order message kept as an alternate path.

Availability differs by market. We built country and market logic so each region sees the correct in-stock, pre-order or coming-soon state and pricing.

Buyers need proof of quality. We built a certificate-of-analysis gallery with real batch numbers per product where held.

Features we added

• 21-plus age-verification gate
• Product catalogue rendered from a single data source
• Certificate-of-analysis proof gallery
• Multi-market availability and pricing logic
• External checkout deep-links
• WhatsApp order fallback
• Research-use-only compliance framing throughout

Pages and content structure

How the website works

A visitor passes the age gate, browses the catalogue, opens a product page with its certificate-of-analysis and pricing, then checks out via the external store link or a WhatsApp order message. Availability adapts by market. Checkout is a hand-off to the external store, so the site records an order request rather than taking an integrated payment.

Responsive development

The storefront is responsive, with mobile checkout and WhatsApp controls. A headless-browser QA harness renders the store past the age gate with no console errors. Device-level testing was not repeated in research.

SEO and performance foundations

The build adds a robots file and XML sitemap and uses canonical URLs to the production domain. This is crawlability and structure work, not a ranking claim.
