Tirzepatide 30mg

Grade:Reagent Grade
Poisonous:NO
Product Type:Peptide Preparations
Properties:Tirzepatide is a weekly preparation, usually injected once a week, for the treatment of type 2 diabetes and weight loss. Its dual mechanism makes it an ideal choice for patients with high requirements for blood sugar and weight control.
Shape:Irregular
Storage:Freezer
Usage:1) Blood sugar control in type 2 diabetes: Tirzepatide significantly lowers blood sugar levels by activating GLP-1 and GIP receptors. It can stimulate insulin secretion, inhibit glucagon release, and delay gastric emptying, thereby effectively improving blood sugar control in patients with type 2 diabetes. It is suitable for patients who still cannot achieve ideal blood sugar control through diet, exercise and oral hypoglycemic drugs (such as metformin or sulfonylureas). 2) Weight management: Tirzepatide performs well in weight management, especially for obese or overweight patients with weight-related comorbidities (such as hypertension, dyslipidemia, hyperglycemia, etc.). It helps patients lose weight by increasing satiety, reducing appetite and delaying gastric emptying. Clinical studies have shown that Tirzepatide can significantly reduce body mass index (BMI) and improve metabolic status. 3) Improvement of cardiovascular health: Tirzepatide also has a positive effect on the cardiovascular system. It can reduce the risk of cardiovascular disease and improve blood pressure and blood lipid levels, thereby providing additional health benefits for diabetic patients. 4) Other potential applications: Although the main indications of Tirzepatide are type 2 diabetes and weight management, it also shows certain potential in the fields of neurological diseases (such as Alzheimer's disease, Parkinson's disease), skin repair, tumor treatment, etc. However, these applications still need further research and clinical trial verification.

Tesamorelin 2mg 5mg 10mg 20mg

Molecular Formula:C221H366N72O67S
Molecular Weight:5135.86 Milligram (mg)
Physical Form:Powder
Properties:Tesamorelin is a synthetic growth hormone-releasing hormone analogue primarily used to reduce visceral fat accumulation (lipodystrophy) in HIV-infected individuals. Its core characteristics can be summarized as follows: 1) Pharmacological Properties: Mechanism of Action: It is a growth hormone-releasing factor (GRF) analogue that binds to and activates GRF receptors in the pituitary gland, stimulating the pituitary to secrete endogenous growth hormone (GH) in a pulsatile manner. Subsequently, growth hormone stimulates the liver to produce insulin-like growth factor 1 (IGF-1), which mediates most of the biological effects, including reducing visceral fat and regulating metabolism. Hepatic Effects: In clinical trials, tesamorelin did not cause elevated serum transaminases or significant liver damage; on the contrary, it was even associated with lowering existing ALT levels, potentially improving non-alcoholic fatty liver disease. 2) Pharmacokinetic Properties: Absorption and Bioavailability: Administered subcutaneously, the amount absorbed into systemic circulation is very limited, with an absolute bioavailability of less than 4%. Its pharmacokinetic characteristics are similar in HIV-infected individuals and healthy subjects, and are not significantly affected by factors such as age, body size, or race. Distribution and elimination: It has a large volume of distribution, averaging 200 liters; the elimination half-life is very short, approximately 8-26 minutes in healthy subjects and approximately 38 minutes in HIV-infected individuals. Metabolism and excretion: There are currently no formal human metabolic studies. 3) Clinical Characteristics: Primary indication: For reducing excess abdominal fat in patients with HIV-related lipodystrophy. It is important to emphasize that this is not a general medication for weight loss. Efficacy: Clinical studies have shown that daily subcutaneous injection of 2 mg for 26 weeks significantly reduces visceral adipose tissue (VAT) (average reduction of approximately 14-18%), with no adverse effects on subcutaneous fat in the extremities. It also lowers triglyceride levels. Administration: Once daily, subcutaneous injection. Dosage varies depending on the drug strength. For example, the recommended dose for the 1 mg/vial strength is 2 mg daily; the recommended dose for the 2 mg/vial strength (Egrifta SV) is 1.4 mg daily. 4) Safety Characteristics: Common Side Effects: Primarily include injection site reactions (such as redness, swelling, pain, and itching), arthralgia, muscle pain, and limb pain. Side Effects to Watch Out For: May cause elevated blood sugar (increased risk of glucose intolerance or type 2 diabetes), therefore, caution should be exercised in diabetic patients. In addition, fluid retention (manifested as arthralgia, carpal tunnel syndrome), allergic reactions (such as rash, shortness of breath), and antibody production may occur (occurring in approximately 50% of patients, but usually does not affect efficacy). Contraindications: Contraindicated in patients with hypersensitivity to any of the drug components, those with an active or previous history of malignancy, and patients with pituitary-related diseases (such as pituitary tumors). Contraindicated in pregnant women as it may harm the fetus. Drug Interactions: Concomitant use with corticosteroids (such as prednisone) may reduce the efficacy of the latter. No clinically significant interactions were observed when used in combination with simvastatin or ritonavir. It has minimal effect on the hepatic CYP3A enzyme system. 5) Chemical Properties: Chemical Nature: It is a polypeptide composed of 44 amino acids and is a synthetic analog of human natural growth hormone-releasing hormone (GHRH). Its chemical structure is C221-H366-N72-O67-S. Structural Modification: The N-terminus of its molecule has been modified (by adding a trans-3-hexenoyl group) to increase its stability and prolong its duration of action. Appearance: Usually a sterile, preservative-free lyophilized powder, which must be dissolved in the matching diluent before use.

Semax 5mg 10mg 30mg

Density:1.391 0.06 Gram per cubic centimeter(g/cm3)
Grade:Research Grade
Poisonous:NO
Product Type:Peptides
Properties:Semax is a synthetic neuroprotective peptide primarily used in stroke research and central nervous system function regulation. As an analog of the adrenocorticotropic hormone (ACTH) fragment, it crosses the blood-brain barrier through a unique mechanism, promoting nerve regeneration and repair. In experimental models, it has shown potential to improve cerebral blood flow and regulate neurotransmitter activity; however, its clinical application requires further validation. I. Structure and Bioactivity: Semax is a synthetic analog of the ACTH (4-10) fragment. Its chemical structure removes the hormonal activity while retaining its neuroregulatory function. Its derivative, Semax acetate (CAS 2828433-33-4), has become the primary form in research due to its enhanced stability and improved bioavailability. This modification allows it to rapidly cross the blood-brain barrier after intranasal administration, with a single dose lasting up to 24 hours, making it suitable for acute neurological injury scenarios. II. Mechanism of Action and Neuroprotective Effects: Semax exerts its effects through a dual pathway: Promoting the expression of neurotrophic factors: Upregulating the levels of BDNF and its receptor TrkB in the hippocampus, directly supporting neuronal survival and synaptic plasticity, and accelerating neural circuit reconstruction after injury; Regulating the neurotransmitter system: Activating the serotonin and dopamine pathways, improving mood and cognitive function. Experiments show that it can counteract cognitive impairment caused by chronic stress, while enhancing D-phenylpropanol-induced motor activity, suggesting that it has a bidirectional regulatory capacity on neural excitability.
Storage:Freezer
Usage:Semax possesses immunomodulatory, nootropic, and neuroprotective activities. Semax can be used in research on central nervous system diseases such as Alzheimer's disease and cerebral ischemia.

LL-37 Chemical

Molecular Formula:C205H340N60O53
Physical Form:Powder
Properties:1. Physical Properties Appearance: The pure product is usually a white or off-white lyophilized solid powder. Net Charge: Under normal bodily conditions (pH 7.4), it carries a strong positive charge of +6. This makes it highly attractive to negatively charged bacterial surfaces. Isoelectric Point (pI): Approximately 10.61. It is a strongly basic polypeptide. 2. Spatial Structure Characteristics Chameleon-like Structure (Structural Plasticity): In pure water: It has no fixed shape and a loose structure, mainly in a random coil state. In the presence of salt or in contact with cell membranes: It rapidly twists into a very stable -helix structure. Perfect "Dual Nature" (Amphiphilicity): When it becomes an -helix, it exhibits dual affinity: The hydrophilic side: One side is lined with positively charged amino acids (lysine, arginine), which readily bind to water and bacterial surfaces. Hydrophobic surface: The other side is lined with water-averse amino acids (leucine, phenylalanine), which prefer to penetrate the lipid layer of bacterial cell membranes. 3. Environmental and Chemical Behavior Characteristics Concentration-dependent "aggregation" (oligomerization): At low concentrations (below 10 M), it prefers to work alone in solution (monomer form). At high concentrations or in saline environments, it aggregates in groups (forming dimers or tetramers). This aggregation behavior protects it from easy degradation by enzymes in the body. Salt sensitivity: The salt ion composition in solution alters its spatial shape. High concentrations of salt act as a shield, blocking its positive charge, thus slightly reducing its direct bactericidal rate, but not affecting its ability to call on immune cells. Protein resistance: Compared to other common peptides, LL-37 exhibits strong resistance to degradation by human proteases when bound to cell membranes, allowing it to survive longer in inflamed wounds.
Shape:other
Smell:Other
Storage:Freezer
Usage:1. Research on Superbugs and Drug-Resistant Bacteria (New Antibiotic Development) With the increasing severity of antibiotic resistance (AMR) problems, LL-37 has become an ideal template for researching new antibacterial drugs. Disrupting Resistant Biofilms: It not only directly kills free bacteria but also disrupts the "bacterial biofilm" formed by Staphylococcus aureus or Pseudomonas aeruginosa. This is an area where many traditional antibiotics are ineffective. Enhancing Drug Efficacy through Combination Therapy: In scientific experiments, researchers often combine low doses of LL-37 with traditional antibiotics, which can significantly improve the antibiotic's effectiveness against superbugs. 2. Chronic Wound Healing and Skin Repair (Clinical Drug Development) LL-37 has shown significant effects in promoting tissue regeneration and has made rapid progress in clinical translation. Treatment of Lower Extremity Venous Ulcers: LL-37-related drugs, supported by institutions such as the Karolinska Institute in Sweden, have entered Phase II clinical trials internationally for the treatment of chronic ulcers caused by varicose veins. Promoting Angiogenesis and Epithelial Growth: It stimulates the growth of vascular endothelial cells, attracts immune cells to wounds, and enables chronic wounds lacking this component (such as diabetic foot) to resume granulation and healing. 3. Gastrointestinal Tract and Mucosal Immune Barrier Research LL-37 is widely present in the human gastrointestinal mucosa. Scientists are using it to study the pathological mechanisms and treatment strategies of inflammatory bowel disease (IBD), gut microbiota dysbiosis, and gastric ulcers. Eye and Respiratory Protection:** Research focuses on how it protects the cornea from infection and its protective role in acute lung injury or respiratory infections. 4. Disease Diagnostic Markers and Targeted Therapy (Psoriasis, etc.) Because the amount of LL-37 is directly related to the level of inflammation in the body, it is also used as a target for medical diagnostics and targeted research. Autoimmune Disease Target: In the skin lesions of patients with psoriasis and rosacea, the expression level of LL-37 is often abnormally elevated and exacerbates inflammation. Therefore, developing drugs that "inhibit or antagonize LL-37" has become a new approach to treating these skin diseases.

In the presence of salt or in contact with cell membranes: It rapidly twists into a very stable -helix structure. Perfect "Dual Nature" (Amphiphilicity): When it becomes an -helix, it exhibits dual affinity: The hydrophilic side: One side is lined with positively charged amino acids (lysine, arginine), which readily bind to water and bacterial surfaces. Hydrophobic surface: The other side is lined with water-averse amino acids (leucine, phenylalanine), which prefer to penetrate the lipid layer of bacterial cell membranes. 3. Environmental and Chemical Behavior Characteristics Concentration-dependent "aggregation" (oligomerization): At low concentrations (below 10 M), it prefers to work alone in solution (monomer form). At high concentrations or in saline environments, it aggregates in groups (forming dimers or tetramers). This aggregation behavior protects it from easy degradation by enzymes in the body. Salt sensitivity: The salt ion composition in solution alters its spatial shape. High concentrations of salt act as a shield, blocking its positive charge, thus slightly reducing its direct bactericidal rate, but not affecting its ability to call on immune cells. Protein resistance: Compared to other common peptides, LL-37 exhibits strong resistance to degradation by human proteases when bound to cell membranes, allowing it to survive longer in inflamed wounds.

Usage:1. Broad-Spectrum Antimicrobial (Natural Antibiotic) LL-37 possesses a very strong direct bactericidal ability and is unlikely to induce bacterial resistance. Eliminating Bacteria: It has a strong killing effect on common bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Antiviral: It can destroy enveloped viruses (such as influenza virus and respiratory syncytial virus), preventing them from penetrating human cells. Inhibiting Fungi: It also has a significant inhibitory effect on fungi such as Candida albicans, which cause skin and mucous membrane infections. Disrupting Bacterial Biofilms: It can break down the "protective shell" (biofilm) formed by bacteria clump together, exposing and eliminating hidden bacteria. 2. Powerful Immunomodulatory Effects LL-37 is not just a "killer," but also a balancer of the immune system. Recruiting Immune Cells (Sentinel Function): When an infection occurs in the body, LL-37 releases signals to attract an "immune army" of neutrophils, macrophages, and other cells to the scene. Neutralizing Endotoxins: When bacteria die, they release toxic lipopolysaccharides (LPS/endotoxins), triggering severe systemic inflammatory responses (sepsis). LL-37 can directly bind to and neutralize these toxins, preventing uncontrolled inflammation. 3. Promotes Wound Healing and Tissue Regeneration LL-37 acts as an accelerator for wound repair when skin and mucous membranes are damaged. Promotes Skin Growth: It stimulates the division and migration of keratinocytes and epithelial cells, promoting rapid wound closure. Promotes Angiogenesis: It induces endothelial cells to form new microvessels, delivering oxygen and nutrients to damaged tissues, which is crucial for the healing of chronic ulcers such as diabetic foot. 4. Potential Anti-tumor and Metabolic Regulation Effects Bidirectional Tumor Regulation: In scientific research, LL-37 has exhibited complex regulatory effects on various cancers. It can inhibit the growth of certain tumors (such as colon cancer) by inducing apoptosis, making it a current research hotspot in cancer immunotherapy.

Product Type:Peptides
Properties:1. Structural and Evolutionary Characteristics: Belongs to the VIP/Glucagon Family High Conservation: VIP peptides are highly conserved throughout evolution. From fish to humans, its amino acid sequence is almost identical (the VIP sequence in humans and rats is 100% identical). This indicates that it plays an extremely fundamental and indispensable role in living organisms. Family Lineage: It belongs to the same family as glucagon and secretin, sharing similar structures but with different functional focuses. 2. Dual Identity: Both a "Hormone" and a "Neurotransmitter" Neurotransmitter/Neuromodulator: It is abundant in the central and peripheral nervous systems. Nerve endings release it to rapidly transmit "relaxation" signals between cells. Gastrointestinal Hormone: It is also released by endocrine cells in the intestines, regulating the secretion of digestive juices and muscle movement through blood circulation. This dual identity allows it to perfectly coordinate the nervous and digestive systems. 3. Biological Activity Characteristics: "Comprehensive Relaxation" and "Potential Anti-inflammatory Effects" These are the core clinical and experimental characteristics of VIP peptides: Potential Relaxant: It is one of the most potent smooth muscle relaxants in the body. It can relax blood vessels, trachea, and gastrointestinal muscles. Immune Brake (Anti-inflammatory): It is known as an "endogenous anti-inflammatory peptide." When the body's immune system is overactivated (such as during a cytokine storm), VIP peptides can inhibit the release of harmful substances (pro-inflammatory factors) from macrophages and T cells, while promoting the secretion of protective substances (anti-inflammatory factors). Neuroprotection: It can protect neurons in the brain from damage caused by toxins and inflammation.

Usage:1. Powerful Anti-inflammatory and Immune-Regulating Effects (Core Functions) In scientific research, VIP peptides are known as the body's "endogenous anti-inflammatory brake." Inhibiting Cytokine Storms: It can prevent immune cells such as macrophages from releasing harmful substances (such as pro-inflammatory factors like TNF- and IL-6), thus cooling down acute or chronic inflammation in the body. Alleviating Autoimmune Problems: It can regulate the balance of T cells, preventing the immune system from mistakenly attacking itself, and has a positive effect on alleviating arthritis and enteritis. 2. Improving Chronic Toxin Damage (A Hot Topic in Functional Medicine) In modern functional medicine, VIP peptides are often used in nasal spray form as a key substance in the later stages of treatment for mycotoxin poisoning and chronic inflammatory response syndrome (CIRS). Repairing the Brain Barrier: It can reduce chronic brain inflammation caused by toxin exposure and help restore the damaged nervous system. Reshaping Hormonal Balance: It can help restore key hormones such as melanocyte-stimulating hormone (MSH), which have decreased due to toxin invasion, to normal levels. 3. Relaxes the Trachea and Supports the Respiratory System VIP peptides are powerful smooth muscle relaxants in the human body. Airway Relaxation: It completely relaxes the smooth muscles of the trachea, which are in a state of spasm and tension, increasing lung ventilation. Pulmonary Circulation: By dilating pulmonary blood vessels, it helps reduce pulmonary artery pressure, alleviating the burden on the heart caused by hypoxia and high blood pressure. 4. Vasodilation and Improved Circulation Lowering Blood Pressure: It directly sends a "dilation" signal to blood vessels, making blood flow smoother and thus helping to lower arterial blood pressure. Supporting Male and Female Health: Due to its powerful local vasodilatory effect, it is clinically used to improve erectile dysfunction (ED) caused by nerve or vascular damage. 5. Protects the intestinal mucosa and regulates digestion Repairs leaky gut: It regulates the tight junctions of intestinal epithelial cells, enhances the barrier function of the intestinal wall, and has a good protective effect against leaky gut syndrome and irritable bowel syndrome (IBS). Stabilizes intestinal motility: It can reduce excessive spasms of the gastrointestinal muscles, promote the secretion of digestive juices, and allow food to move more smoothly through the intestines. 6. Regulating the biological clock and improving sleep Synchronizing circadian rhythms: VIP peptides are secreted more during the day, directly participating in the control of our brain's biological clock and helping to regulate the normal pattern of "being awake during the day and secreting melatonin for sleep at night.
