Semax and Selank Bundle

Semax and Selank Bundle — Nootropic Research Peptide Pair + Lab Supplies

Semax + Selank Bundle is supplied in Australia by Omega Peptides Australia from domestic stock, with same-day dispatch on orders placed before 12pm. Also searched as Semax Selank kit or nootropic peptide bundle, it provides Semax and Selank together with the consumables needed to run both.

The Semax and Selank Bundle, also called the Limitless Bundle, pairs the two best-known Russian nootropic heptapeptides with the consumables needed to reconstitute and handle them. Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is an analogue of the ACTH(4-10) fragment, and Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is an analogue of the immune peptide tuftsin. Both were developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and share a C-terminal Pro-Gly-Pro tail added to slow enzymatic breakdown. The kit is also searched for as a Semax Selank bundle or semax and selank kit.

Semax is studied for attention, memory and neuroprotection through BDNF, melanocortin and enkephalin pathways, while Selank is studied for anxiety, stress and immune endpoints through GABAergic and enkephalin mechanisms. The two are frequently investigated side by side because their profiles are complementary rather than overlapping.

Omega Peptides Australia supplies both peptides as high-purity (≥99% HPLC) COA-verified lyophilised powders in sealed 10mg vials, dispatched the same day from within Australia on orders placed before 12pm, with the batch Certificate of Analysis for each lot published in our COA library.

What is included

• 1 × Semax 10mg vial, lyophilised powder ($79.99 individually)
• 1 × Selank 10mg vial, lyophilised powder ($79.99 individually)
• 1 × Bacteriostatic Water 10mL ($29.99 individually)
• 10 × insulin syringes for drawing and transferring reconstituted solution
• 4 × alcohol swabs for cleaning vial stoppers before puncture

Key research areas

• Cognition and memory Semax raises BDNF and TrkB expression in the rodent hippocampus and has been examined in passive-avoidance and maze tasks; Selank has been studied for memory consolidation under stress.
• Stress and anxiety Selank produces anxiolytic-like behaviour in rodent elevated plus-maze and open-field paradigms, attributed to changes in GABAergic gene expression. Semax shows anxiolytic-like effects in some stress models by a different route.
• Enkephalin degradation Both peptides inhibit enkephalin-degrading enzymes in human serum in vitro, a shared mechanism traced to their common Pro-Gly-Pro tail.
• Neuroprotection Semax has been investigated in rat models of focal cerebral ischaemia for effects on neuronal survival and gene expression, and in Russia it is registered as a nasal solution used in stroke care.
• Immune and neuroimmune signalling Selank inherits immunomodulatory activity from tuftsin, including effects on interleukin-6 and T helper cytokine balance, linking the pair to research on stress, immunity and cognition.

Why these are supplied together

Semax and Selank are structural cousins with different parents. Semax carries the ACTH(4-7) core and is studied for attention, memory and neuroprotection; Selank carries the tuftsin core and is studied for anxiety, stress and immune regulation. Because they share the Pro-Gly-Pro tail and its enkephalinase-inhibiting property but differ upstream, researchers often run them in parallel to compare a neurotrophic profile against an anxiolytic one under identical conditions.

The consumables are included because both peptides are supplied lyophilised and must be reconstituted before use. Bacteriostatic water, preserved with 0.9% benzyl alcohol, keeps a reconstituted vial usable for up to 28 days, and one 10mL vial is enough for both peptides.

Specifications

Available sizes and pricing

The bundle is supplied in one configuration at $169.99. Bought separately, the Semax vial ($79.99), Selank vial ($79.99) and 10mL bacteriostatic water ($29.99) total $189.97, so the kit saves $19.98 before counting the syringes and swabs. See our kits and bundles collection for other kits.

• Semax and Selank Bundle — $169.99 (20mg of peptide in total, about $8.50 per mg including supplies)

Quality and COA verification

Both peptides in the bundle are tested independently by Janoshik Analytical, with HPLC used to quantify purity and mass spectrometry to confirm that each vial's molecular mass matches its expected sequence. A Certificate of Analysis is issued for every batch of Semax and Selank and published in our COA library, so each vial's lot number can be matched to its own report. The peptides are supplied as lyophilised powders in sealed sterile vials for stability, and the kit is packed with protective cushioning for domestic transit within Australia.

Frequently asked questions

What is in the Semax and Selank Bundle?
The bundle contains one 10mg vial of Semax, one 10mg vial of Selank, one 10mL vial of bacteriostatic water, ten insulin syringes and four alcohol swabs. Both peptides are lyophilised powders in sealed sterile vials, each backed by an independent batch Certificate of Analysis, and everything is supplied for in-vitro laboratory use only.

What are Semax and Selank?
Semax and Selank are synthetic seven-amino-acid peptides developed at the Institute of Molecular Genetics in Moscow. Semax is derived from the ACTH(4-10) fragment and is studied for attention, memory and neuroprotection. Selank is derived from the immune peptide tuftsin and is studied for anxiety, stress and immune regulation. Both share a Pro-Gly-Pro tail that slows enzymatic breakdown.

Do I need bacteriostatic water and syringes?
Yes, because both peptides are supplied as lyophilised powder and must be dissolved before use in any assay. Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, which keeps a reconstituted vial usable for up to 28 days under refrigeration. The syringes transfer diluent and solution accurately, and the swabs clean vial stoppers. All are included.

How much do I save with the bundle?
The Semax vial, Selank vial and 10mL bacteriostatic water cost $189.97 when bought separately, against $169.99 for the bundle, a saving of $19.98. The ten insulin syringes and four alcohol swabs are included on top of that, so the effective saving is larger for anyone who would otherwise buy those consumables separately.

Can I buy the items separately?
Yes. Semax 10mg and Selank 10mg are each sold individually at $79.99, bacteriostatic water is available in 10mL and 3mL vials, and insulin syringes are sold in packs. The bundle exists for convenience and a lower combined price; researchers who need only one peptide can order the components from their own product pages.

Can I buy Semax or Selank at Chemist Warehouse or a pharmacy in Australia?
No. Neither Semax nor Selank is registered on the Australian Register of Therapeutic Goods, so they are not stocked by Chemist Warehouse, Priceline or any other retail pharmacy, and no Australian medicine contains either peptide. The lyophilised compounds in this bundle are research-grade chemicals supplied for laboratory work, a different category of product from a medicine.

Can Australian compounding pharmacies supply Semax or Selank?
Compounding pharmacies in Australia may only prepare a medicine for a named patient against a valid prescription, and the TGA has published guidance warning pharmacists about compounding and supplying unapproved peptide products. Neither peptide is an approved medicine here, so neither is a routine compounding item. Research suppliers such as Omega Peptides Australia provide the lyophilised research compounds for in-vitro work, not for dispensing.

How do you reconstitute Semax and Selank?
Let each vial reach room temperature, swab the stopper, then add bacteriostatic water slowly down the inside wall of the vial rather than onto the powder. Swirl gently until clear and do not shake. Reconstitute each peptide in its own vial rather than combining them. The diluent volume depends on the concentration required; our reconstitution calculator can help. Refrigerate at 2–8°C and use within 28 days.

How should the bundle be stored?
Keep the lyophilised Semax and Selank vials sealed at 2–8°C short term or −20°C long term, protected from light and moisture, and avoid repeated freeze-thaw cycles. Bacteriostatic water is stored at room temperature and used within 28 days of first puncture. Reconstituted peptide solutions are kept refrigerated at 2–8°C and used within 28 days.

Where can I buy the Semax and Selank Bundle in Australia?
The bundle is available directly from Omega Peptides Australia. Stock is held domestically, orders placed before 12pm are dispatched the same day, and both peptides are supported by independent batch Certificates of Analysis you can check before ordering. The individual peptides are listed in our research peptides collection.

What does the Semax and Selank Bundle cost in Australia?
The bundle is $169.99 from Omega Peptides Australia. It contains 20mg of peptide across the two vials, about $8.50 per mg with the bacteriostatic water, syringes and swabs included. The two vials alone would cost $159.98, and adding 10mL bacteriostatic water separately brings that to $189.97. Prices are in Australian dollars with tracked shipping calculated at checkout.

How do I get the Semax and Selank Bundle online in Australia?
Open the bundle product page, add it to your cart and complete checkout. Orders ship with tracked domestic delivery in discreet, unbranded packaging that gives no indication of the contents. Orders placed before 12pm on a business day leave the same day, and later orders are dispatched the next business day. Tracking details are emailed once the parcel is lodged.

Are Semax and Selank legal in Australia?
Omega Peptides Australia supplies Semax and Selank strictly for lawful in-vitro laboratory research. They are not approved by the TGA for human or veterinary use and are not sold as medicines or supplements. Purchasers are responsible for ensuring their intended use complies with all applicable laws. This research-only condition applies to every item in the bundle.

Semax vs Selank: what does each do and why are they studied together?
Semax is an ACTH(4-10) analogue studied for attention, memory and neuroprotection through BDNF, melanocortin receptors and enkephalinase inhibition. Selank is a tuftsin analogue studied for anxiety, stress and immune regulation through GABAergic gene expression, enkephalinase inhibition and interleukin-6. They share a Pro-Gly-Pro tail but differ upstream, so studying them together lets a neurotrophic and an anxiolytic profile be compared under identical conditions.
