Summary
Transparent Labs runs a well-structured product page with strong clarity, a compelling subscription offer, and exceptional social proof volume (6,729 reviews with star rating above the fold). The brand's strongest dimension is clarity — the value proposition, ingredient callouts, and pricing are all immediately readable. The single most critical gap is mobile page speed: a 23.5-second LCP will cause the majority of cold mobile visitors to bounce before the page loads, undermining every other conversion element on the page.

Top Fixes
- 1
Fix mobile page speed — LCP of 23.5s is conversion-killing. Compress and lazy-load images, serve next-gen formats (WebP/AVIF) for the hero product shot, and audit third-party scripts. Getting LCP under 4s should be the single highest priority on this page.
- 2
Add a sticky 'Add To Cart' bar on mobile scroll — the CTA is buried below multiple selectors and has no persistent presence as users scroll. A bottom-anchored sticky button with price and flavor shown would reduce drop-off at the decision point.
- 3
Add a short product video (15–30s autoplay loop showing mixability, scoop size, or a real customer using it) — no video exists on the page and this is the highest-impact visual merchandising gap in the supplement category. Also surface the Informed Choice/Informed Protein badges and a return/money-back guarantee snippet directly adjacent to the Add To Cart button on mobile.
Findings
PSI mobile score of 52/100 with LCP of 23.5 seconds and FCP of 7.0 seconds. These are critically slow load times — a 23.5s LCP means the hero product image takes over 23 seconds to fully render on a cold mobile load, which will cause significant bounce before the page is even usable. TBT of 220ms is acceptable but the FCP/LCP figures are the dominant problem.
mobile performance · critical
The 'Add To Cart' button on mobile appears below the frequency/subscription selector and is not visibly sticky on scroll in the screenshot. A cold visitor must scroll past the image carousel, product description, ingredient callouts, size picker, flavor picker, and subscription toggle before reaching the CTA — no persistent sticky bar is evident.
purchase friction · high
Desktop thumbnail strip shows 4 visible images (product shot, supplement facts panel, how-to-use graphic, lifestyle/in-use shot) with a carousel arrow suggesting more. On mobile the hero image is a product-only white-background shot; lifestyle imagery exists but is below the fold in thumbnails. No video content is visible anywhere on the page — a significant missed opportunity in a category where mixability and texture demos drive conversion.
visual merch · high
Subscribe & Save toggle is prominently featured with a clear $6.00 savings callout ($59.99 → $53.99), free shipping benefit listed, and a 'Free Starter Kit Unlocked' incentive — this is a well-executed subscription upsell. A 'Whey Protein + Free Starter Kit' bundle is also visible below the CTA. Variant selection (2LB/4LB size, 21 flavors via dropdown) is clearly laid out. Free USA Shipping Over $99 is shown in the top banner. Return/guarantee policy is collapsed under 'Shipping & Returns' accordion and not surfaced near the CTA — a missed trust signal at the moment of decision.
purchase friction · medium
Mobile hero image is cropped/not full-width — the right side of the product tub is clipped and a 'Setting for Tra...' text panel is partially visible, creating a cluttered above-the-fold experience rather than a clean hero moment.
visual merch · medium
Star rating (4 stars) and review count (6,729 Reviews) are displayed directly below the product title on both mobile and desktop — excellent placement near the fold. Review volume of 6,729 earns maximum points. However, no customer photo reviews or UGC are visible in the screenshots; only text-based social proof is present above the fold.
social proof · medium
Desktop screenshot shows 'Informed Choice' and 'Informed Protein' certification badges in the Third-Party Testing section, and the page links to 'View Third-Party Testing' — strong trust signals. However, these certifications are below the fold and not surfaced near the CTA on mobile. No press/media 'As Seen In' bar is visible.
social proof · medium
Product name 'Grass-Fed Whey Protein Isolate' is visible above the fold on mobile, price ($59.99 / $53.99 subscribe) is clearly shown, and the hero description 'This is as clean as whey protein gets, sourced exclusively from grass-fed cattle with absolutely no artificial sweeteners, food dyes, or fillers' functions as a strong value proposition. Target customer (health-conscious, clean-label buyer) is clearly implied. CTA reads 'Add To Cart' — functional but generic; no differentiated copy like 'Get My Protein' or 'Start Building'.
