A great number of active compounds in the human body are present in peptide form. Peptides take part in hormonal, neural, cell-growth and reproductive processes, helping regulate the physiological functions of diverse systems and cells. They activate associated enzyme systems, support the permeability of intermediate metabolic membranes, influence DNA transcription, and modulate the synthesis of specific proteins, thereby producing defined physiological outcomes. As essential participants in a wide range of cellular activities, peptides are produced by cells themselves and help govern their functional behavior. They also function as signal transmitters conveying neural information, and act as delivery carriers — transporting nutrients, vitamins, biotin, calcium and beneficial trace elements to the body's cells, organs and tissues. As key physiological modulators, peptides broadly regulate bodily functions, boost physiological activity, and exert notable biological effects.

Product Benefits
-
I. Key Functional Properties
-
Calming effect: Selank interacts with the brain's neurotransmitter system through gamma-aminobutyric acid (GABA) receptors. It supports GABA-mediated neurotransmission, moderates overactivity of the nervous system, and helps reduce feelings of anxiety. Research studies indicate that Selank may help alleviate symptoms associated with generalized anxiety disorder. Unlike some conventional calming compounds, it is not reported to induce drowsiness, sedation or dependency, and may contribute to overall well-being.
-
Cognitive support: Selank shows a positive influence on brain regions linked to learning and memory. It upregulates the expression of brain-derived neurotrophic factor (BDNF), supports neuronal growth, survival and differentiation, and promotes synaptic plasticity. These effects may help enhance memory, attention and learning performance, making it of interest to students in academic settings and professionals seeking to support mental productivity.
-
Immune-related activity: As a derivative of tuftsin, Selank plays a role in modulating the body's immune system. It may enhance immune-cell activity — for example, by supporting the phagocytic function of macrophages — and helps regulate the release of inflammatory factors, contributing to improved defense against pathogens and overall immune balance.
In the nervous system, Selank inhibits the activity of enkephalinase in the brain, slowing the breakdown of enkephalin and raising its concentration. It interacts with opioid receptors, contributing to calming and comfort-related effects. At the same time, it helps regulate the release and metabolism of neurotransmitters such as serotonin and dopamine, supporting emotional stability, motivation and cognitive function. In the immune system, Selank modulates immune-cell signaling pathways, helping immune cells recognize and respond to foreign agents and maintaining immune homeostasis.
III. Safety Profile and Usage Notes
Selank exhibits a favorable safety profile. It has not been shown to cause embryotoxicity, teratogenicity, allergenic reactions or irritation, and is not associated with drug dependence. However, due to limited safety data, it is not recommended for use by pregnant women, breastfeeding women, or individuals under 18. People currently taking other compounds — particularly those affecting the central nervous system — should consult a qualified professional before use to avoid potential interactions.
Product Usage
Metabolic Research Applications
Beyond its role in glucose-related metabolic pathways, tirzepatide has drawn broad research attention in areas such as appetite signaling, dietary intake, energy balance, and body-weight dynamics. Its activity across two receptor pathways offers a wider framework for metabolic research.
Tirzepatide is under investigation for its interaction with signaling pathways linked to hunger and fullness. Studies suggest these pathways may play a role in modulating appetite, satiety sensations, and overall food consumption.
By acting on both GIP and GLP-1 receptors at the same time, tirzepatide allows researchers to examine metabolic regulation through two complementary routes rather than relying on a single-receptor mechanism.
Energy and Lipid Metabolism
Tirzepatide is also explored in studies involving adipose tissue, energy expenditure, lipid metabolism, and body composition, adding extra research angles into metabolic balance and fat distribution.
Integrated Metabolic Regulation
The combined influence of the GIP and GLP-1 pathways may support coordinated metabolic responses and overall metabolic homeostasis. Experimental outcomes can differ depending on study design, models, dosage, and other research conditions.

Q&A
Q: How soon can I receive my order?
A: We will arrange shipment as quickly as possible after payment is confirmed. Delivery usually takes approximately 7–15 days, depending on the destination and logistics conditions.
Q: What is the minimum order quantity?
A: The minimum order quantity is 1 box, and each box contains 10 individually packed vials.
Q: Can the price be adjusted?
A: Yes. We always aim to provide customers with competitive pricing. The final price may vary depending on the selected specification, order quantity, and other purchasing requirements. Please contact us for a detailed quotation.
Q: How should peptide products be transported and stored?
A: Peptide products in lyophilized powder form can be transported at room temperature in sealed vacuum packaging. Products in dissolved form should be kept refrigerated at 2°C–8°C.
For long-term storage, it is recommended to keep the lyophilized powder sealed with desiccant at −20°C or −80°C. Proper storage helps maintain product stability and minimize degradation.

ECHEMI Editorial Reference
Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.
