What is inside

  • What amino spiking is, and why it is legal. Cheap free-form aminos are nitrogen. Standard protein testing measures nitrogen. That is the entire loophole.
  • The glycine line. One number on the amino panel that separates real complete whey from a padded one. Check it on any tub you already own.
  • How to read an 18-amino panel in under a minute — what to look at, in what order, and what to ignore.
  • Isolate, concentrate and blend compared on price per gram of protein rather than price per tub, which is the comparison that actually decides value.
  • Why a brand that hides its amino profile has made a choice, and what that choice usually is.
Who it is forAnyone paying premium prices for protein who has never checked whether the number on the front survives contact with the panel on the back.
