Hyaluronic acid

Basic Info. Hyaluronic acid is a naturally occurring substance in your body known for its ability to retain moisture. Found in connective tissues, this powerful compound acts like a sponge, drawing in and holding onto water. It’s recognized for its ability to hold up to 1,000 times its weight in water, making it a key player in maintaining skin's hydration and elasticity. As we age, our body’s natural production of hyaluronic acid decreases, which can contribute to dryness and the formation of fine lines. That’s where topical comes in hyaluronic acid by applying it through serums or moisturizers, you can boost your skin’s hydration levels and restore a youthful, dewy glow. ...

FG Loop(FGL)

Basic Info. FG loop peptide (FGL) is derived from the neural cell adhesion molecule (NCAM). NCAM is a glycoprotein (a protein that has sugar attached to it) and is found on the surface of nerve cells (neurons) and glial cells (protect neurons). Research shows that NCAM activates FGL which in turn stimulates the production of new projections of developing neurons. FGL also plays an integral role in the formation of synapses between neurons and the proliferation of stem cells – both of these important mechanisms enhance cognitive capacities and protect against stroke and other chronic, debilitating brain diseases. ...

Lemon Bottle

Basic Info. Lemon Bottle is a non-surgical cosmetic procedure that involves injecting a solution into targeted fat areas to break down fat cells. It is marketed as a quick and relatively painless way to reduce localized fat deposits. However, there are concerns about its safety and effectiveness,as the exact composition of the solution and the long-team effects are not fully understand. ...

HMG

Basic Info. HMG is used in the treatment of general infertility in patients with amenorrhea and low gonadotropin secretion caused by functional or organic disorders of the diencephalon or anterior pituitary. ...

snap-8

Basic Info. SNAP-8 is an octapeptide widely used in skin care products. It can effectively reduce facial wrinkles, especially on the forehead and around the eyes. It is considered a natural alternative to Botox, which reduces wrinkles by reducing the contraction of facial muscles. It can also bind to neurotransmitter receptors on nerve cells, blocking the transmission of nerve signals, thereby reducing muscle contraction and wrinkle formation. It can also help improve the skin's barrier function, enhance the skin's resistance, prevent skin moisture loss, and maintain skin elasticity. ...

Survodutide

Basic Info. Survodutide (also known as BI 456906) is a glucagon receptor/glucagon-like peptide-1 receptor (GCGR/GLP-1R) dual agonist, jointly developed by Boehringer Ingelheim and Zealand Pharma, and is intended to treat metabolic diseases such as obesity and non-alcoholic steatohepatitis. Survodutide is a drug with an innovative mechanism of action and is expected to become a potential option for the treatment of obesity and metabolic-related diseases. Multiple clinical studies are underway to evaluate its safety and efficacy. ...

cagrilintide 5mg+Semaglutide 5mg

Basic Info. Composition: It is a fixed-dose combination of the long-acting amylin analog Cagrilintide and the glucagon-like peptide-1 receptor agonist Semaglutide. Mechanism of action: Cagrilintide, as an amylin receptor agonist, can significantly suppress appetite and effectively delay gastric emptying; Semaglutide, as a GLP-1 receptor agonist, can significantly enhance insulin secretion and strongly inhibit the release of glucagon. At the same time, it further slows gastric emptying. The combination of the two is excellent in blood sugar control and weight management. ...

Semax

Basic Info. Semax acetate is a BBB-penetrable adrenocorticotropic hormone-like peptide and can form stable complexes with Cu 2+ . Semax acetate is a synthetic peptide analog of Adrenocorticotropic hormone (ACTH) (4-10). Semax acetate has immunomodulatory, nootropic and neuroprotective activities. Semax acetate can be used in the research of central nervous system diseases such as Alzheimer's disease and cerebral ischemia. ...

SS-31

Basic Info. SS-31, also known as Elamipretide, is a mitochondria-targeted tetrapeptide that improves mitochondrial function and is currently undergoing clinical trials for various diseases, including heart failure and mitochondrial myopathy. It interacts with cardiolipin, a phospholipid abundant in the inner mitochondrial membrane, and enhances electron transfer, ATP synthesis, and reduces reactive oxygen species (ROS) production. ...

GHRP-2 Acetate

B asic Info. GHRP-2 acetate is a synthetic hexapeptide that stimulates the release of growth hormone (GH) by acting on the hypothalamus and pituitary gland. GHRP-2 enhances the natural growth hormone releasing signal, leading to increased GH secretion. It suppresses the activity of somatostatin, a hormone that inhibits GH production. It activates ghrelin, a peptide hormone that influences GH production and appetite. ...

GHRP-6 Acetate

Basic Info. GHRP-6 acetate is a synthetic peptide that acts as a growth hormone (GH) secretagogue, stimulating the release of GH in the body. It is an agonist of the growth hormone secretagogue receptor (GHSR), also known as the ghrelin receptor, and it inhibits the binding of other GHS-R agonists like MK-0677 (Ibutamoren). It stimulating GH release witjout affecting the release of thyroid-stimulating hormone (TSH),luteining hormone (LH),or follicle-stimulating hormone. ...

CJC-1295 Whitout DAC

Basic Info. CJC-1295 without DAC works by mimicking the action of GHRH. When administered, it binds to GHRH receptors in the pituitary gland, which leads to an increase in the secretion of growth hormone. ...

CJC-1295 without DAC 5mg + IPA 5mg

Basic Info. CJC-1295 (no DAC): Mimics natural growth hormone-releasing hormone (GHRH), transiently stimulating the pituitary gland to release GH (short half-life, requiring multiple daily injections). Ipamorelin (IPA): Stimulates GH secretion via the ghrelin receptor pathway, without significantly affecting cortisol or prolactin levels, offering a higher safety profile Elevated GH and IGF-1 levels enhance amino acid uptake in muscle cells, reducing catabolism (muscle breakdown). It also promotes cartilage repair and increases bone mineral density (particularly beneficial for middle-aged/older adults or sports injury recovery). ...

CJC-1295 With DAC

Basic Info. CJC-1295 With DAC (Drug Affinity Complex) is a long-acting growth hormone-releasing hormone (GHRH) analog. By binding to the DAC (sustained-release carrier), it significantly extends its half-life (approximately 7-10 days), enabling sustained and stable pulsatile GH release, thereby elevating IGF-1 levels. Accelerates Injury Recovery: Shows potential benefits for tendon, ligament, and cartilage repair (ideal for post-surgical or sports injury rehabilitation). Targets Stubborn Fat Breakdown: Particularly effective against abdominal and visceral fat (offers more gradual but sustained effects compared to short-acting peptides). ...

TB500(Thymosin B4 Acetate）

Basic Info. Thymosin Beta-4 (Tβ4), also called TB-500 is a synthetic version of natural peptide consisting of 43 amino acids. This naturally occurring peptide plays a vital role in repairing and regeneration of injured cells and tissues by reducing apoptosis, inflammation, and microbial growth after injury. It is released by various cell types, including platelets and macrophages, and binds to actin, promoting cell migration and differentiation of stem/progenitor cells to form new blood vessels and regenerate tissue. It was studied also for wound healin. ...

P21 (P021)

Basic Info. P21 (P021) is a peptide that is commonly used to increase levels of brain-derived neurotrophic factor (BDNF), thereby promoting neuronal growth and neuroprotection, especially in brain regions associated with Alzheimer's disease. In animal models, P21 has been shown to enhance cognitive function and inhibit the formation of amyloid plaques and Tau proteins, which are the main features of Alzheimer's disease. ...
