The Importance of Peptides:
      Many active substances in the human body exist in the form of peptides. Peptides are involved in a wide range of physiological processes, including hormonal regulation, neural signaling, and cell growth and reproduction. Their significance lies in their ability to regulate the physiological functions of various bodily systems and cells, activate specific enzyme systems, modulate the permeability of metabolic membranes, control DNA transcription, or influence the synthesis of specific proteins—all of which ultimately yield distinct physiological effects. Peptides are essential substances that participate in diverse cellular functions; they can be synthesized within cells to regulate their functional activities. Within the body, peptides also serve as neurotransmitters, facilitating the transmission of information. Furthermore, they act as transport vehicles, delivering vital nutrients—such as vitamins, biotin, calcium, and various trace elements—to cells, organs, and tissues throughout the body. As crucial physiological regulators, peptides are capable of comprehensively modulating human physiological functions, enhancing and supporting physiological activities, and fulfilling significant biological roles.

Semax is a synthetic neuroprotective heptapeptide developed by a Russian molecular biology research institution, derived from a fragment of the endogenous neuropeptide ACTH. This high-purity, laboratory-grade material is suitable for applications such as primary neuronal cultures, cerebrovascular endothelial cell assays, cellular models of neural injury, and the investigation of signaling pathways related to cognitive function. It is widely used in laboratory research within the fields of neurobiology, cerebrovascular cell biology, and the pathology of neurodegenerative diseases.

Functions of Selank:

   Semax can penetrate the blood-brain barrier, acting upon various signaling pathways within neurons and cerebral microvascular endothelial cells; in *in vitro* culture systems, it activates multidimensional networks for neural repair and the regulation of cerebral circulation.

It promotes the expression and secretion of various neurotrophic factors within precursor neurons in the hippocampus and cerebral cortex, accelerates the growth of synapses, and stabilizes the structural foundation for signal transmission between neuronal populations.

It optimizes the physiological state of cerebral microvascular endothelial cells in co-culture models of brain tissue, stimulates the formation of microvascular tubular networks, and enhances the efficiency of nutrient and oxygen transport.

It inhibits the excessive release of excitatory neurotransmitters under stress, mitigates damage to neuronal membranes caused by excitotoxicity, and reduces the incidence of programmed neuronal cell death (apoptosis).

It regulates the balance of inflammatory mediator secretion in mixed neuron-microglia culture systems, alleviates low-grade chronic neuroinflammation, and reduces the progressive erosion of neural tissue structures.

It increases the levels of intracellular antioxidant proteins, clears accumulated oxidative metabolites, and slows the aging and functional decline of neurons under long-term, suboptimal culture conditions.

It modulates the metabolic activity of glial support cells, establishes a stable nutritional microenvironment for neurons, and sustains the long-term viability of primary neural cells throughout extended culture periods.

Frequently Asked Questions:

1. How do I place an order?
Please send me a message specifying the types and quantities of the products you need, and I will calculate the total cost for you.

2. What are the delivery times and shipping methods?
Once your payment is received, we will ship your order via carriers such as FedEx, DHL, UPS, or Australia Post. Delivery typically takes 5–15 days.

3. How should I store the peptides after receiving them?
Peptides in lyophilized (freeze-dried) powder form can be shipped at room temperature via vacuum packaging, while peptides in solution must be refrigerated at 2°C–8°C. For long-term storage, lyophilized powders should be kept in a sealed container with a desiccant at -20°C or -80°C to minimize degradation.

4. What payment methods are accepted?
We accept:
•⁠ ⁠Credit Card (Visa / MasterCard / Amex)
•⁠ ⁠Apple Pay
•⁠ ⁠Google Pay
•⁠ ⁠PayPal
•⁠ ⁠Bank Transfer (SWIFT)
•⁠ ⁠ USDT / Bitcoin
•⁠ ⁠Wise
