The Challenge
PepCore Labs supplies research peptides to laboratories and independent researchers across the UK, and it is a category where trust does most of the selling. Buyers look at purity documentation long before they look at price, and most of the competition ships from overseas with slow delivery, thin product information and crypto only payments. The brand had proper HPLC tested stock and a UK dispatch operation behind it, but nothing online that made any of that obvious.
The commercial side was just as demanding. The catalogue needed filtering by category, price and rating without reloading the page. Product pages had to carry vial sizes, batch references and handling notes while still reading cleanly on a phone. The client also wanted subscriptions, coupons and an affiliate programme running through one checkout, alongside age and research use verification and a UK GDPR consent notice. A stock multipurpose theme was never going to hold all of that together and stay fast.
