The last column divides the price by the pure Selank we estimate each vial holds, about 10.10 mg. | Selank pack | Each vial | You pay | Off the single price | Each pure Selank mg | | ----------- | --------- | ------- | -------------------- | ------------------- | | Single vial | $150 | $150 | none | $14.85 | | Three vials | $121.50 | $364.50 | 19% | $12.03 | | Five vials | $108 | $540 | 28% | $10.69 | | Ten vials | $90 | $900 | 40% | $8.91 | So a ten pack of Selank costs $5.94 less per pure mg than one vial. Every tier sits on the [Selank price per vial page](https://www.peptaralabs.io/selank-price-per-vial) too. ## Step 2: Read the Selank lot report Our Selank batch carries the code SEL-260406-A. Its certificate number is COA-2026-4806. | Line on the Selank report | Result | | ------------------------- | ----------------------- | | Purity by HPLC | 99.10% | | Identity | confirmed by LC-MS | | Net Selank weighed | 10.19 mg in a 10mg vial | Here is a small extra most Selank listings never work out. The vial holds 0.19 mg above its label. At the single vial rate of $15 per labelled mg, that overfill is worth about $2.85 of Selank you are not charged for. You can open the report yourself in the [COA library](https://www.peptaralabs.io/coa). Search for COA-2026-4806, then make sure the lot printed there says SEL-260406-A. If the two codes ever differ, write to us before the Selank vial is opened. ## Step 3: Choose delivery * Ho Chi Minh City: Selank orders in by 7pm arrive that same day. * Anywhere else in Vietnam: 1 to 3 days, with no shipping fee. * Outside Vietnam: plan on 5 to 10 business days for Selank to reach you. ## Where Selank stands in research Selank was built in a lab from tuftsin, a tiny peptide linked to the immune system. Scientists study how it acts on GABA and serotonin signals in the brain. In Russia, one clinical trial weighed it against phenazepam, an older calming drug. A separate rat project tested Selank alongside diazepam in animals kept under stress for a long time. *Sources:* [*Vyunova et al., Protein Pept Lett 2018, PMID 30255741*](https://pubmed.ncbi.nlm.nih.gov/30255741/)*;* [*Medvedev et al., Zh Nevrol Psikhiatr 2014, PMID 25176261*](https://pubmed.ncbi.nlm.nih.gov/25176261/)*;* [*Kasian et al., Behav Neurol 2017, PMID 28280289*](https://pubmed.ncbi.nlm.nih.gov/28280289/) ## Why Selank is sold as a research compound Only Russia has registered Selank. In every other country it counts as a research chemical. That is why our Selank vials go to lab work and never to people. We give no Selank dose here and make no claim about what it will do. ## Selank buyer FAQ **Which Selank pack gives the lowest cost per milligram?** The ten pack does, at $8.91 for each pure mg. Choose it on the [Selank order page](https://www.peptaralabs.io/selank). **Can I check the Selank lab report before paying?** Yes. COA-2026-4806 is open to anyone in the library, with no login and no order needed first. **Is this Selank a nasal spray?** No. You receive dry Selank powder in a sealed 10mg vial, and the report covers that vial only. **How quickly does Selank reach Hanoi or Da Nang?** Orders inside Vietnam outside Ho Chi Minh City usually land in 1 to 3 days, free of charge. ## Sources * Selank, GABA and serotonin: Vyunova et al., Protein Pept Lett 2018, PMID 30255741 ([PubMed](https://pubmed.ncbi.nlm.nih.gov/30255741/)) * Selank compared with phenazepam: Medvedev et al., Zh Nevrol Psikhiatr 2014, PMID 25176261 ([PubMed](https://pubmed.ncbi.nlm.nih.gov/25176261/)) * Selank with diazepam in stressed rats: Kasian et al., Behav Neurol 2017, PMID 28280289 ([PubMed](https://pubmed.ncbi.nlm.nih.gov/28280289/)) ## About Peptara Labs Peptara Labs ([peptaralabs.io](https://www.peptaralabs.io/)) is a top rated and trusted research peptide supplier, rated 4.96 out of 5 across 401 verified orders, and it ships Selank from lot SEL-260406-A.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://peptara-labs.gitbook.io/peptaralabs-docs/buy-selank-peptide.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
