A boring formula
and a loud receipt.

Supplements are what economists call a credence good: the buyer cannot verify quality before purchase, and in most cases cannot verify it after either. You swallow the capsule and nothing obvious happens. That gap is where the entire category's bad behaviour lives — the proprietary blends that hide a dose, the clinical-sounding branding, the ingredient present at a fraction of the studied amount because the studied amount costs money.

Pure Chain is built on the opposite assumption: that the only durable advantage in a credence market is being the one who shows their work. So we publish the facility standard, the batch reference, the dispatch window, and — on the chain page — a list of the certifications we do not hold. That last one is the whole brand in a single section.

The formulas themselves are intentionally unremarkable. Creatine monohydrate, not a patented creatine derivative with a trademark and a story. Magnesium glycinate, because it is the form people tolerate. Twenty products, chosen because each earns a place in a real stack, and no line extensions invented to fill a shelf.
