Results from this study5

No result from this study comes from a test of the peptide.

Natural levels measured5

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelRandomized controlled trialOther

    In patients with acute ischemic cerebrovascular disease given electro-acupuncture and routine treatment, CSF VIP increased after the course of treatment.

    In plain wordsIn people with acute ischemic cerebrovascular disease, electro-acupuncture with routine treatment raised the body's own VIP in spinal fluid.
