A product in a supplement's own table shows its price per dose there; a combination, never ranked against single ingredients, shows the price of one serving. Amounts are per serving as each label states them, and the amounts to pick from are filters, not advice on how much to take. “Against typical” compares the active ingredient each product provides with the middle price per dose of every product of the same form in stock. The line shows each pack price since it was first checked (the record starts on 17 September 2026); every day's changes are in the price refresh log.
