JYM Supplement Science has a structurally sound product page — pricing, variants, Subscribe & Save, and bundle upsell are all present and functional — but the page is critically undermined by a 29/100 PSI mobile score that makes it nearly unusable for cold mobile traffic. The brand's strongest dimension is purchase friction mechanics (subscription toggle, bundle, free shipping bar), but the single most critical gap is mobile performance: a 15-second LCP means most paid and organic mobile visitors never see the page they're being sent to.
PSI mobile score is 29/100 with LCP of 15.1s, FCP of 5.3s, and TBT of 1,670ms. A 15-second largest contentful paint means the majority of cold mobile visitors will bounce before the page is usable. This is a critical revenue leak.
