Executive Summary

British Peptide Labs, a UK-based research peptide supplier, had no Meta Ads presence. Facing strict UK advertising regulations and Meta’s aggressive policy enforcement, they were hesitant to invest in paid media. Our agency built their complete Meta Ads infrastructure — implementing advanced tracking, developing a “British Research Excellence” creative framework, and executing a conversion-only campaign strategy optimizing directly for purchases. No awareness campaigns. Every pound spent drove toward revenue. Within 90 days, British Peptide Labs scaled from £0 to over £130,000/month in revenue, achieving a 3.7× ROAS and a £30.50 CPA.
