What the evidence shows

Khavinson bioregulator literature: open and controlled Russian trials on heart muscle-system function with cytomax peptides; cardiac function endpoints.

Tier is our appraisal of the human evidence at the dose we use: Tier 1 = multiple randomized trials; Tier 2 = human trials, fewer or smaller; Tier 3 = mechanistic, traditional or early human data; Tier 4 = emerging. Ingredients below Tier 2 are included only where the safety record is long and the traditional use is specific.
