Selank 10mg ships as a 10mg vial of lyophilized powder, held in stock in the United States and priced at $48 per vial. Purity is 98% or higher. Bundle pricing lowers the per-vial price automatically in the cart: $45 per vial at two units, $43 at three, and $40 at five. Orders placed before 4PM ET leave the same day, seven days a week.
What researchers look for in a Selank supplier
Selank is not hard to find. Finding it at a published price, in stock, from a supplier that ships the day you order is the harder problem. Most of the friction in this market is quote-only pricing, preorder listings, and parcels that sit for a week before tracking appears.
Published pricing, no quote request. Selank 10mg is $48 a vial on the page. The bundle tiers are published too: $45 per vial at two, $43 at three, $40 at five. You can budget a project before contacting anyone, and the cart matches the page.
Stock physically held in the United States. Vials ship from US inventory, not through a drop-ship arrangement routed via a third country. That is what makes a same-day cutoff possible. A domestic order stays a domestic parcel, with domestic transit times and no customs step.
A consistent purity standard across the catalog. Selank is held to 98% purity or higher, the standard applied to every compound we list. Material below it does not go on the site. Consistency matters more than one good figure, because a program repeating an assay needs the same input every time.
A person answers within one business day. Questions about the 10mg vial, the purity standard or how the lyophilized cake is packed for transit get a direct answer from someone who has the specification in front of them. If a vial arrives damaged or the order is wrong, one email starts a replacement. No ticket queue and no phone tree.

What Selank is, in research terms
Selank is a synthetic heptapeptide, sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, abbreviated TKPRPGP. Molecular formula C33H57N11O9, molecular weight 751.87 Da, CAS number 129954-34-3. Structurally it is tuftsin, the endogenous tetrapeptide Thr-Lys-Pro-Arg, carrying a Pro-Gly-Pro extension on the carboxyl terminus. That tail is not decorative. It resists the peptidases that clear tuftsin within minutes, which is why the analog stays measurable long enough to study. We supply it as a lyophilized powder in a 10mg vial, SKU CRP-SEL-10.
Selank keeps appearing in preclinical designs because it decouples two things a classical GABA-A ligand keeps welded together. It is not a benzodiazepine and does not occupy the benzodiazepine site, yet rodent behavioral assays report overlapping readouts. A three-arm design running Selank, a benzodiazepine reference and vehicle through one protocol lets an investigator ask which downstream markers track behavior and which track receptor occupancy. That is why Selank recurs in rodent screening designs as the non-benzodiazepine arm that still moves the same behavioral endpoints.
The published work is mostly rodent. Rat and mouse studies pair standard behavioral paradigms with molecular readouts from dissected hippocampus, amygdala and cortex, profiling GABA-A receptor subunit transcription by quantitative PCR and microarray. Separate ex vivo work incubates the peptide with blood plasma and follows enkephalin degradation by HPLC. Neurochemical arms quantify serotonin, dopamine and their metabolites, and immune arms profile interleukin expression in blood cells. Our overview, Selank: GABAergic Modulation and Enkephalinase Inhibition, works through both threads.

Bundle pricing, printed on the page
| Quantity | Per vial | Order total | Savings |
|---|---|---|---|
| 1 vial | $48 | $48 | – |

| 5 vials | $40 | $200 | $40 |
A rodent design with a benzodiazepine reference arm and a vehicle arm runs Selank across weeks, not an afternoon, and each cohort dissected for hippocampus, amygdala and cortex consumes its own material. Reordering halfway introduces a variable nobody chose. Bundle pricing is 5% off at two vials, 10% at three and 15% at five, floored to whole dollars, with no code anywhere in the flow. A five vial order sits above $150, so domestic shipping comes off the total.
US stock, international shipping and same-day dispatch
Orders placed before 4PM ET are dispatched the same day, seven days a week. Not the next business day, not after a processing window. Tracking is emailed the same day the parcel leaves. Weekend orders go out on the weekend. That cutoff works only because stock sits in a US warehouse instead of being ordered in after you pay.
Domestic Standard Shipping is $12, arrives in 2 to 5 business days and is free over $150. Expedited 2-3 Day is $39. Overnight is $95. Standard International is $40 flat, 10 to 20 business days, free at $500 and above. Express International is $100 flat, 5 to 10 business days. Every rate is flat and shown before you pay.
Storage and handling
Store the sealed lyophilized vial at minus 20C for long-term holding, or at 2 to 8C if it will be used within a few weeks. Let a cold vial warm to room temperature before opening so moisture does not condense onto the cake. Once reconstituted, keep the solution at 2 to 8C and handle it as a short-lived working stock. Our storage and handling page sets out the full windows, and the reconstitution calculator converts a diluent volume into the resulting concentration in one step.
Checkout, payment and support
Checkout takes Visa and Mastercard directly on the site and finishes in one pass. No crypto wallet, no bank transfer instructions, no invoice emailed back an hour later, no second site to log into. You enter the card, the order confirms, and the dispatch clock starts.
Support replies within one business day. If a vial arrives damaged, or the wrong item is in the box, email us with the order number and a photograph and we send a replacement. We do not run a returns gauntlet on a $48 vial.

Frequently asked questions
What is Selank?
Selank is a synthetic heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, abbreviated TKPRPGP. It is an analog of the endogenous tetrapeptide tuftsin, extended at the carboxyl terminus with a Pro-Gly-Pro tail that slows enzymatic breakdown. Its molecular formula is C33H57N11O9, its molecular weight is 751.87 Da and its CAS number is 129954-34-3. Published preclinical work examines it in rodent models and ex vivo plasma assays.
Why buy Selank from Core Research Peptides?
Price is published, stock is real and dispatch is same day. A 10mg vial is $48, with bundle pricing at $45, $43 and $40 per vial for two, three and five units. Inventory is held in the United States, so an order placed before 4PM ET leaves the same day, seven days a week. Card checkout finishes in one pass, and support replies within one business day.
What purity is your Selank?
Selank is held to a purity standard of 98% or higher. That standard applies across the whole catalog, and material below it is not listed. Purity matters most for consistency: an assay repeated across several vials should see the same input each time.
How fast do you ship Selank, and what does shipping cost?
Orders placed before 4PM ET are dispatched the same day, seven days a week, weekends included, and tracking is emailed the same day the parcel leaves. Within the United States, Standard Shipping is $12 and arrives in 2 to 5 business days, free on orders over $150. Expedited 2-3 Day is $39 and Overnight is $95. Every rate is flat and shown at checkout before payment.
Do you ship Selank internationally?
Yes. Standard International is $40 flat and arrives in 10 to 20 business days, free on orders of $500 and above. Express International is $100 flat and arrives in 5 to 10 business days. International parcels follow the same before 4PM ET dispatch schedule. Customs handling and local import requirements are the buyer’s responsibility.
Do you offer bundle pricing on Selank?
Yes. Two vials bring the per-vial price to $45, for $90 and a $6 saving. Three bring it to $43, for $129 and a $15 saving. Five bring it to $40, for $200 and a $40 saving. The discount applies automatically in the cart with no code. A coupon code stacks on top of bundle pricing.
How should Selank be stored?
The sealed lyophilized vial is stored at minus 20C for long-term holding and at 2 to 8C for short-term holding of a few weeks. Let a cold vial reach room temperature before opening so moisture does not condense into the powder. Once reconstituted, hold the solution at 2 to 8C and handle it as a short-lived working stock.
