Idea: Imagine a peptide vial that already contains 2 mL of bacteriostatic water sealed above a lyophilized peptide puck
Understanding the published evidence behind each component helps researchers justify their formulation choice
Tests for IGF-1 Levels IGF-1 status can be checked with a simple blood test, though these are not routinely performed
Intestinal dysbiosis, by increasing inflammation, can alter the tryptophan pathway with increased indoleamine 2,3-dioxygenase (IDO) activity that reduces the tryptophan metabolism to serotonin and increases the kinurenine pathway with overproduction of quinolinic acid (QA), which has inflammatory effects in the brain [105]
Animal studies 61 have shown that central or peripheral administration of GLP-1 receptor agonists, such as Ex-4, increases ACTH and CORT levels in rats, activates the HPA axis, induces anxiety-like behavior, and impairs swallowing function
