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.
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.
Body Protection Compound-157 is a synthetic peptide derived from a protein found in human gastric juice. It has shown remarkable healing properties in research studies.
Thymosin Beta-4 (TB-500) is a naturally occurring peptide present in almost all human and animal cells. It plays a crucial role in tissue repair and regeneration.
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement.
Semax is a synthetic peptide derived from ACTH (adrenocorticotropic hormone). Developed in Russia as a nootropic and neuroprotective agent.
Delta Sleep-Inducing Peptide is a neuropeptide that promotes delta wave sleep, the deepest and most restorative phase of the sleep cycle.
PT-141, also known as Bremelanotide, is a synthetic peptide analog of alpha-melanocyte-stimulating hormone. It is the only FDA-approved treatment for hypoactive sexual desire disorder (HSDD) in premenopausal women.
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.
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.
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.
MK-677, also known as Ibutamoren, is an orally active growth hormone secretagogue. Unlike peptides, it can be taken orally and has a long half-life, providing 24-hour GH elevation.
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.
NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.
SS-31, also known as Elamipretide or Bendavia, is a mitochondria-targeted tetrapeptide. It has been studied extensively for mitochondrial diseases, heart failure, and age-related decline in mitochondrial function.
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of IGF-1 with extended half-life and enhanced potency. The modifications prevent binding to IGF binding proteins, increasing bioavailability.
PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.
Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.
VIP is a 28-amino acid neuropeptide with wide-ranging effects throughout the body. It acts as a neurotransmitter, neuromodulator, and immune regulator with particular importance in gut and lung function.
Mod GRF 1-29 (Modified GRF 1-29, also called CJC-1295 without DAC or Tetrasubstituted GRF 1-29) is a modified growth hormone-releasing hormone analog with improved stability over natural GHRH.
Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.
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.
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.
Lactoferricin is an antimicrobial peptide derived from lactoferrin, a protein found in milk and other secretions. It has potent antibacterial, antiviral, and antifungal properties.
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.
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.
Teriparatide (Forteo) is recombinant human parathyroid hormone (1-34), FDA-approved for osteoporosis treatment. It's unique among osteoporosis drugs in that it stimulates new bone formation.
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.
BNP is a cardiac neurohormone released primarily by ventricles in response to volume/pressure overload. It's a major biomarker for heart failure and has therapeutic applications as nesiritide.
