99% purity Dihexa Prebiotic dipeptide white powder 100mg 1000mg

Dihexa is a synthetic peptide compound originally developed by a research team at a U.S. university by modifying a naturally occurring substance in the human body (angiotensin IV), with the goal of creating a “memory-enhancing” compound. What makes it unique is its mechanism of action: rather than directly stimulating a specific receptor in the brain, it “leverages” a protein in the body associated with cell growth and survival, amplifying its signals to promote the formation of new connections between brain cells. To put it simply, the brain’s memory and thinking rely on a dense network of connections between neurons, and Dihexa’s core function is to help the brain “build bridges”— —encouraging neurons to form more new connections. The more connections there are, the stronger the “hardware foundation” for learning, memory, and cognition becomes. It has several notable characteristics: First, it is extremely potent—it works at extremely low concentrations in the lab, and its efficacy has even been compared to that of the brain’s own key neurotrophic factor (BDNF).

Second, it can cross the blood-brain barrier and is taken orally, making it very convenient for practical use. Currently, all findings regarding its effects come from animal and in vitro studies. For example, in mouse models of aging or brain injury, it has been shown to significantly improve spatial memory and learning ability. As a result, it is primarily used in scientific research exploring Alzheimer’s disease, cognitive impairment, and recovery from brain injury. It has not yet entered human clinical trials nor been approved for market release. In short, Dihexa is a research-grade peptide marketed for “enhancing memory and promoting neural connections in the brain.”

(1) Promotes cognition and memory consolidation: Dihexa exhibits significant cognitive-enhancing activity, reversing learning deficits, improving spatial learning ability, and promoting memory consolidation and retrieval.

(2) Induces synaptogenesis and dendritic spine formation: Dihexa induces dendritic spine formation and synaptogenesis in hippocampal neurons, acting similarly to HGF itself. These effects can be blocked by HGF antagonists and sh-RNA targeting c-Met.

(3) Neurotrophic Activity: In neurotrophic activity assays, Dihexa exhibits potency seven orders of magnitude higher than brain-derived neurotrophic factor (BDNF). It activates the c-Met receptor, stimulates neurogenesis, and protects neurons from injury.

(4) Enhanced HGF/c-Met Signaling: In the presence of subthreshold HGF concentrations, Dihexa induces c-Met phosphorylation and increases HGF-dependent cell scattering, significantly amplifying HGF's ability to activate c-Met.

(5) Oral Activity with Long Circulating Half-Life: Dihexa exhibits oral bioavailability, blood-brain barrier permeability, and metabolic stability, enabling it to maintain a prolonged circulating half-life in vivo.
