Product Description
Melatonin peptide is an indolamine small‑molecule hormone (not an amino‑acid‑based peptide, commonly listed among research peptide raw materials). Secreted by the pineal gland, it mainly activates MT1 and MT2 receptors to regulate circadian rhythm, and also exhibits antioxidant, anti‑inflammatory and anti‑apoptotic bioactivities.
Supplied as lyophilized powder in vials, it is widely used in pre‑clinical research covering circadian rhythm, sleep mechanism, oxidative stress, neuroprotection and reproductive endocrinology.

Product Applications
1. Circadian rhythm-related research: used in animal models to explore the regulatory mechanisms of biological clocks and sleep-wake cycles, and to conduct research on related topics such as rhythm disorders and jet lag.
2. Oxidative stress and damage protection research: Melatonin peptide is used to study the free radical scavenging effect, analyze the antioxidant, anti‑inflammatory and anti‑apoptotic effects, and apply it in various tissue oxidative damage models to evaluate tissue protection effects.
3. Neuroprotective research: applied to animal models of brain injury and neurodegeneration to examine the protective effect on neurons and explore the regulatory mechanisms of brain inflammation and neuronal apoptosis.
4. Reproductive endocrinology research: Conduct animal experiments to study the effects of melatonin on hormone secretion and gonadal function, for preliminary research related to reproductive rhythm and endocrine imbalance.





Product Packaging
Our peptide lyophilized powder is packaged in clear glass vials and sealed with crimp-on aluminum-plastic caps, which effectively preserves the activity of the lyophilized powder. For bulk shipments, the vials are neatly stored in transparent plastic trays. The trays isolate and secure each vial to prevent breakage caused by collision between glass bottles, ensuring product safety during storage and international logistics.
