Straight Label
No seed oils. No corn- and soy-fed meat. No synthetic fibers or fake fragrance. We read the labels and check the certificates so you don’t have to — and every pick shows its receipts.
A brand is here because its claims on seed oils, organic or soy/corn-free feed, natural fibers or natural ingredients were checked against the brand's own pages, a retailer listing or a certifier's own database — and held up. Full evidence and sources are on every card, behind "Evidence and sources." Nothing here is paid placement: "Shop" links go straight to the brand's own site and earn Straight Label nothing.
"Best fit" ranks brands by points: 3 for Seed-Oil-Free, Soy/Corn-Free Feed or Lab-Tested, 2 for any other badge, 2 for Tier A, minus 1 per flag. A brand that fails a core goal goes to the bottom of every list, marked Below the bar, whatever its score. Today that is Vital Farms (hens fed mainly corn and soy) and Tessemae's (sunflower oil in every dressing).
A flag marks something that conflicts with the goals of this index, such as corn and soy in feed or a mixed line with synthetics. Flagged brands stay listed, so you see the trade-off; use "Hide brands with flags" to filter them out. Unproven allegations (lawsuits, investigations) are flagged as unproven.
Some seals, such as the Seed Oil Free Alliance seal and NSF or Informed Sport certification, are paid for by the brand. We count them because an independent party still does the testing, and we say so on the card.
No paid placement and no affiliate ranking. A brand cannot pay to change a tier or move up in results. "Shop" buttons are plain links to the brand's own site. Check the flags and the specific product before you buy.
Not listed yet. The peptide market is mostly "research use only" vendors, and a brand's own claim of third-party testing is not enough. Nothing is added until it has a per-batch certificate of analysis from an accredited, independent lab, tied to a lot number on the product — and injectable peptides for human use stay out entirely until reviewed by a lawyer or regulator-savvy advisor. This is not medical advice.
