Prices are each vendor’s listed price before shipping, unless a verified code is marked as included. Some outbound links are affiliate links and PeptideTech keeps a fee from sellers on checkout orders; neither affects grades or scores, or order apart from the labelled featured partner.

- Package. Every row is a single vial (1 vial · 5mg labelled); multi-vial packs, kits and bundles are left off this comparison.
- Price scope. Each vendor’s listed item price in US dollars for the US market, before shipping and sales tax, which its checkout sets. A code is deducted only when its discount was verified in a cart. These are research-use package prices, not clinic, prescription or monthly programme costs.
- Current or historical. A price is current when its source was read in the last seven days; historical rows are older listings, kept with their date and left out of the lowest price and the structured data.
How offers are selected
- Every row is one exact package: 5mg, one form, US market, US-dollar price as the vendor lists it.
- Vials, multi-vial packs, bundles, pens, sprays and blends stay in separate comparisons; kits and subscriptions are left out.
- Offers are ranked by displayed price; a code is included only when its discounted price was verified in a cart. A referral code is not a confirmed discount.
- A price is current when its source was read in the last 7 days; older listings stay visible as historical and are excluded from the lowest price. Read each offer’s source date, stock, currency and market.
- A catalogue name or alias (a vendor code name) is the seller’s claim: check it against the product specification and the lot report.
- Grades come from lab documents, business records and service terms, scored the same way for every vendor; no vendor can pay for a grade or rank.

short answers
Selank questions
How much does Selank cost?
Selank 5mg costs from $30.00 to $33.59 across 2 vendors with current prices. The cheapest in-stock offer is Amino USA at $30.00 ($6.00/mg), observed Nov 8, 2026. Other sizes (10mg) are listed in the price-by-size table. Across every size, current in-stock listings run from $4.00/mg (10mg at LA Peptides) to $6.72/mg (5mg at Cenexa Labs). These are US-dollar item prices for research-use packages, before shipping, sales tax and unverified codes; they are not the monthly cost of a clinic or prescription programme.
Where is the cheapest place to buy Selank?
Amino USA has the cheapest in-stock offer among the 2 vendors with current prices for Selank 5mg, at $30.00, with code TECH10 available through our link but not deducted from the listed price. “Cheapest” uses the displayed price, including a code only when its discounted price is explicitly verified, and excludes shipping.
Is the Selank 5mg price for one vial or several?
One. Every 5mg offer compared here is a single vial labelled 5mg, so its price per mg is the item price divided by 5mg. Multi-vial packs, kits and bundles are left off the comparison, because a pack is a different unit from one vial. Check the selected option on the vendor’s page before ordering. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
How is the Selank 5mg price per mg calculated?
Item price divided by the labelled amount: $30.00 ÷ 5mg = $6.00/mg for the cheapest current offer (Amino USA, observed Nov 8, 2026). The figure uses the label, not a measured assay: a certificate’s purity or net-content result is reported separately and can differ from the label. Shipping, tax and unverified codes are not included.
What sizes of Selank are available?
Selank is sold in 2 sizes: 5mg, 10mg. This page compares the selected package; availability differs by form, size and vendor.
Are the Selank prices and discount codes current?
Each offer shows the date its price was last observed at the vendor (newest for 5mg: Nov 8, 2026); loading the page does not check vendors again. Automated sources run on a schedule and other sources are checked by hand, so dates differ by vendor. A listing not seen for 7 days is marked historical and excluded from current prices. A code is deducted from a price only when its discount was verified in a cart; for 5mg, 2 offers carry a code shown before its discount.
Which Selank coupon codes work?
Code TECH10 was accepted in a recorded cart check. Listed prices remain before this coupon; confirm eligibility for the selected items in your cart. Code PEPTECH was accepted in a recorded cart check. Listed prices remain before this coupon; confirm eligibility for the selected items in your cart.
Is Selank FDA approved?
A product-specific regulatory review has not been completed. This catalogue entry does not establish authorization, lawful sale or import eligibility in any country; check the exact product and destination with the relevant regulator. Every listing on this page is a research-use-only product, whatever the status of any approved medicine with the same active compound.
Has Selank been tested in clinical trials?
No ClinicalTrials.gov registration listing Selank as an intervention was matched (checked October 1, 2026). This is a gap in matched records, not proof that no study exists. PubMed indexes 3 selected human studies in which participants received Selank, most recently “[Optimization of the treatment of anxiety disorders with selank]” (Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova, 2015). The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
Is Selank legal to buy?
A research-labelled listing does not establish legal eligibility in every jurisdiction. Product status, purpose, import rules and destination matter. Review the jurisdiction-specific sources in the reference notes; PeptideTech does not provide a worldwide legality determination.
How expensive is Selank?
Current in-stock Selank listings range from $4.00/mg (10mg at LA Peptides) to $6.72/mg (5mg at Cenexa Labs) across 5 vendors. Package size and vendor change the price per mg, so compare the per-mg column rather than the package total. PeptideTech records each vendor's listed price; it does not set or explain them. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.

Research reference
Selected sources reviewed
Selank is a synthetic seven-amino-acid analogue of tuftsin with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). The selected primary study examines gene expression in rat brain tissue.[1][2]
Identity checks
The Selank compound record (PubChem CID 11765600) specifies the unacetylated peptide. N-acetyl Selank has a separate compound record (CID 133082488); the terminal modification is part of the chemical identity.[1][3]
Selank diacetate has a separate record (CID 155804769), and the reviewed rat experiment used a diacetate salt. An acetate counterion is different from covalent N-acetylation. Confirm the sequence, terminal modifications, salt and formulation before comparing a vial, spray or blend with a study material.[4][3][2]
Identity records and a preclinical gene-expression study
The original experiment used male Wistar rats and measured expression of neurotransmission-related genes in the frontal cortex using real-time PCR. This selected review covers identity and one rat experiment. It does not assess human clinical efficacy or long-term safety, and cannot establish equivalence of a commercial vial, spray or blend to the studied material.[2]
Regulatory context
A product-specific regulatory review has not been completed. This catalogue entry does not establish authorization, lawful sale or import eligibility in any country; check the exact product and destination with the relevant regulator.
