What is — Selank
Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro), developed as a stabilized analog of the endogenous immunomodulatory peptide tuftsin. Peptworks supplies it as a lyophilized powder, 10 mg per vial, strictly as a laboratory research reagent (Research Use Only). It is not a medicine, supplement, cosmetic or medical device, and is not for human or animal consumption. Buyers can order unbranded bulk vials or white-label them under their own brand, from stock already held inside the EU.
In preclinical and in-vitro research models, Selank has been investigated as a tool compound for modulation of GABAergic and serotonergic signaling, for its influence on the expression of neurotrophic factors such as brain-derived neurotrophic factor (BDNF), and for effects on the enzymatic stability of endogenous enkephalins. As a tuftsin analog, it is also used in immunomodulation assays. All mechanisms described here refer to laboratory research contexts only and are not claims about effects in humans.
Research
- Anxiolytic-like behavior in rodent behavioral models
- GABAergic and serotonergic neurotransmission studies
- Neurotrophic factor (BDNF) expression assays
- Enkephalin degradation and peptidase-activity research
- Immunomodulation studies as a tuftsin analog
- Learning and memory tasks in animal cognition models

Advantages
- Investigated for anxiolytic-like effects in rodent behavioral models
- Used as a reference tool compound in neuropeptide and BDNF-expression studies
- Studied for modulation of GABA and serotonin metabolism in preclinical assays
- Applied in immunomodulation research owing to its tuftsin-analog structure
- High-purity (≥98% HPLC) lyophilized format supports reproducible in-vitro work
Safety
- Animal studies generally report low acute toxicity for the compound
- No standardized human safety profile has been established; data are limited to research models
- Effects and tolerability outside controlled preclinical settings are not characterized
- As a research reagent, handle with standard laboratory PPE and follow institutional safety protocols
Ideal for
- Neuroscience and behavioral-pharmacology research laboratories
- Academic and institutional groups studying neuropeptides and cognition models

Frequently asked questions
Where can I buy Selank in bulk in the EU?
Peptworks supplies Selank (10 mg lyophilized vials) in bulk from stock already held inside the EU, so orders ship intra-community in 3-5 business days with no customs. You can order unbranded bulk vials or white-label them under your own brand. This is a B2B research-reagent supply channel (Research Use Only); Peptworks does not sell to end consumers.
What is the wholesale price of Selank per vial?
Selank pricing is public and per-vial, with combined-volume discounts applied to your whole order: EUR 15.00/vial at 100 units, EUR 12.30 at 300 units (-18%), EUR 11.25 at 500 units (-25%) and EUR 10.20 at 1000 units (-32%). The discount is a single tier based on your combined total units, not stacked.
Can I get white-label Selank with my own brand?
Yes. Peptworks offers two formats: unbranded bulk vials, or white-label where vials are labelled with your own brand and boxed. There is a one-time label setup fee of EUR 180 for orders under 100 units; it is free from 100 units. Each box carries the Peptworks label plus a unique QR that links to the batch Certificate of Analysis.
What is the minimum order for Selank?
The minimum order is 10 units (1 box) per reference. Vials always ship in boxes of 10. You can combine references across your order, and the combined total units determine which volume discount tier applies.
How is the Selank Certificate of Analysis verified?
Every batch has an independent Certificate of Analysis covering HPLC purity (≥98%) and heavy metals. The box carries a unique QR code that links to that specific batch's CoA, which you can authenticate through Peptworks. This gives your own downstream customers a traceable, per-batch quality record.
How do I pay and how fast does Selank ship?
Payment is by USDC bank transfer / invoice; there is no card checkout on site. Because stock is held inside the EU, orders ship intra-community in 3-5 business days with no customs clearance. The full ordering site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL).
