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.
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.
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.
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.
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.
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.
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.
Melanotan I (afamelanotide) is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH). It is FDA-approved as Scenesse for erythropoietic protoporphyria (EPP), a rare genetic disorder causing severe sun sensitivity.
Matrixyl (Palmitoyl Pentapeptide-4) is a signal peptide that stimulates collagen and extracellular matrix production. It is one of the most well-studied anti-aging peptides with proven efficacy for wrinkle reduction.
Melanotan II is a synthetic peptide analog of α-MSH with broader receptor activity than Melanotan I. It produces tanning effects and has notable effects on sexual function and appetite suppression.
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.
SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of wrinkles by modulating muscle contraction. It is often called 'topical Botox' though it works through a different mechanism.
Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.
Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide that stimulates collagen production. It's one of two peptides in the Matrixyl 3000 complex, working synergistically with Palmitoyl Tetrapeptide-7.
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.
Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate) is a synthetic tripeptide that mimics the effect of Waglerin-1, a peptide found in Temple Viper venom. It's used in cosmetics for anti-wrinkle effects.
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.
Palmitoyl Tetrapeptide-7 is an anti-inflammatory peptide that reduces IL-6 secretion. Combined with Palmitoyl Tripeptide-1, it forms Matrixyl 3000, addressing both collagen production and inflammation.
AHK-Cu (Copper Tripeptide-3, Alanine-Histidine-Lysine Copper) is a copper peptide similar to GHK-Cu but with different properties. It's used for hair growth and skin rejuvenation applications.
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.
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.
