Storage & reconstitution

Before opening

Lyophilised powder is stable at ambient temperature in transit. On arrival, store sealed vials in a cool, dry, dark place. For storage beyond three months, keep at −20 °C.

Reconstitution

Add bacteriostatic water slowly down the inner vial wall. Do not shake — swirl gently until fully dissolved.

After reconstitution

Refrigerate at 2–8 °C and protect from light. Use within 30 days. Discard if the solution becomes cloudy or discoloured.

For laboratory research use only. Not for human or veterinary consumption. Not a drug or dietary supplement.

Research record · preclinical

Three characterised lines of work

Selank is a synthetic heptapeptide analogue of the endogenous immunopeptide tuftsin, studied in research involving neuropeptide signaling, regulatory peptide biology, and neuroendocrine communication pathways. Unlike receptor-selective agonists, Selank is investigated for its broader signaling profile and potential interactions with multiple regulatory networks, including pathways associated with GABAergic and monoaminergic signaling. Pure Forge Labs supplies high-purity Selank, tested and verified by accredited labs for consistent batch quality. Sold for research use only.

01

Tuftsin analogue

The peptide is an analogue of tuftsin, a tetrapeptide reviewed extensively for immunomodulatory activity. Reviews of tuftsin and its derivatives set out the structural family the compound belongs to and the range of activities attributed to its analogues.

02

GABAergic gene expression

In rat frontal cortex, expression of 84 genes involved in neurotransmission was measured one and three hours after administration of the peptide or GABA. Significant changes were found in 45 genes at one hour and 22 at three hours, with correlation between the two treatments. A parallel study in IMR-32 neuroblastoma culture compared the peptide with GABA and olanzapine on the same gene panel.

03

Inflammation-related transcripts

A separate study followed the temporal dynamics of inflammation-related gene expression under the peptide, and behavioural work in rats reported attenuation of aversive signs in a naloxone-precipitated morphine withdrawal model, with the peptide compared against diazepam.

In vitro applications

Research area Assay
Neurotransmission genes qPCR panel of 84 GABAergic and monoamine transcripts in rat cortex
Cell-culture comparison Gene expression in IMR-32 neuroblastoma against GABA and olanzapine
Inflammatory transcripts Temporal dynamics of inflammation-related gene expression
Behavioural models Naloxone-precipitated morphine withdrawal in rats
Tissue morphology Hepatocyte morphometry under chronic foot-shock stress

As with Semax, this body of work comes largely from a small number of Russian groups, and the readouts are transcriptional and behavioural in animals rather than clinical endpoints. The compound holds no FDA approval.

Common questions

Ordering, handling and compliance. Anything not covered here, write to support@pureforgelabs.com.

What does research use only actually mean?

Every compound we sell is supplied for laboratory research and development only. It is not a drug, not a supplement, and not intended to diagnose, treat, cure or prevent any condition in humans or animals. Buying from this site means you are acquiring it for in vitro or other controlled research work.

Who is allowed to order?

Purchasers must be 21 or older and are responsible for compliance with the law where they take delivery. We ship to research institutions, laboratories and qualified individual researchers. We do not ship to jurisdictions where these compounds are restricted.

How do I read the certificate of analysis?

Check three things in order. First, the lot code on the certificate matches the code printed on your vial. Second, the HPLC chromatogram shows a single dominant peak with the stated purity figure. Third, the LC-MS mass matches the expected molecular weight, here 1419.56 g/mol. Anything that does not line up, send us the lot code.

How do I reconstitute and store it?

Add bacteriostatic water slowly down the inner wall of the vial and swirl — never shake. Once in solution, refrigerate at 2–8 °C, protect from light and use within 30 days. Unopened vials keep at ambient temperature short term, or at −20 °C beyond three months.

When does it ship and how?

Orders placed before 2 PM Pacific dispatch the same working day. Domestic delivery is two days, with tracking sent on dispatch. Shipping is free on orders over $200. International orders go out with a commercial invoice; transit is typically five to nine days.

What payment methods do you take?

Institutional purchase orders and bank transfer are available on wholesale accounts — apply through the wholesale programme and we will set up terms.

What if a vial arrives damaged?

Photograph the vial and outer packaging and email us within 48 hours of delivery. We replace damaged or compromised vials at our cost. Unopened vials can be returned within 30 days; opened vials cannot be resold and are not returnable.

Do you handle bulk and wholesale orders?

Yes. Volume pricing on this page runs to five vials; beyond that, a wholesale account gives tiered pricing, reserved lots and consolidated shipping. Reserved lots matter for multi-month studies where you need the same batch throughout.
