Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.
Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.
ANP is a cardiac hormone released by atrial myocytes in response to stretch. It promotes natriuresis, diuresis, and vasodilation, playing key roles in blood pressure and fluid regulation.
Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.
GHK-Cu is a naturally occurring copper peptide found in human plasma, saliva, and urine. It plays important roles in wound healing, tissue repair, and has shown anti-aging properties in research.
Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.
Sermorelin is a synthetic analog of GHRH consisting of the first 29 amino acids of the natural hormone. It was previously FDA-approved for GH deficiency diagnosis and treatment in children.
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.
Cortexin is a polypeptide complex derived from pig brain cortex, used clinically in Russia and Eastern Europe for neurological conditions including stroke recovery, traumatic brain injury, and cognitive decline.
MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.
Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia.
LL-37 is the only human cathelicidin antimicrobial peptide. It plays crucial roles in innate immunity and has shown diverse biological activities including antimicrobial, immunomodulatory, and wound healing properties.
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
