Selank Price

The selank price moves three times between the product page and the payment screen: $47.50 on the listing, $23.75 once the code PEPTIDEDECK is entered, then $38.75 with the flat $15 domestic shipping added back on. A 10 mg vial reaches the doorstep about a week later.

Only the third figure describes a first order, and none of them describes a second one. An opening purchase is really a setup, because dry powder arrives alone and the water, syringes and wipes are separate lines you have not bought yet. A reorder is just material, and it settles close to the $2.38 per milligram the discounted vial is genuinely worth. So this page follows the money in the order it actually moves, listing to checkout to doorstep to reorder, because on a total this small the sequence decides the figure more than the discount does. This is research material sold for laboratory use, not for human consumption.

One thing worth fixing before the arithmetic starts. Selank is a synthetic heptapeptide, seven residues in the order Thr-Lys-Pro-Arg-Pro-Gly-Pro, catalogued as PubChem CID 11765600 with the formula C33H57N11O9 and a molecular weight of 751.9. It is an analogue of tuftsin with a proline tail added to slow enzymatic breakdown. It is not a fifteen-residue compound and not a coenzyme, which matters here only because those are sold in different quantities and the per-unit figures do not transfer.

Selank price on the listing, before anything is added

There is one Selank line in the catalogue. That makes the first table short.

The $60.00 figure is still shown struck through on the product page, so the visible saving is larger than the one the code is responsible for. Read it as two separate reductions: the vendor moved the list to $47.50, and the code halves whatever the list happens to be on the day you buy.

The half hour after the discount, where the total moves again

The code fires and the subtotal reads $23.75. Then three things happen in sequence, and each one adds to it.

Shipping is first. Domestic orders carry a flat $15 unless the cart clears $250, and one discounted vial clears about a tenth of that. So the realistic figure at the payment step is $38.75, which is 63 percent more than the number that made you click.

Consumables are second, and they are the ones that catch a first order. A Selank vial arrives as a dry, sealed cake of lyophilised powder and nothing else. Bacteriostatic water is a separate product with its own line. So are sterile syringes and alcohol wipes. None of them is expensive alone, and together they are the difference between the price you planned for and the invoice you got.

Timing is third, and it is free. Dispatch is same day on orders placed before 2 P.M. Central, and the next business day after that. Ordering at 1:45 P.M. on a Tuesday and ordering at 2:15 P.M. on the same Tuesday cost exactly the same and arrive a day apart.

None of that is a hidden charge. It is simply that a dry vial is one line on an invoice and a working bench is four, and the difference only shows up once, on the order where you own none of it yet.

The quantity tiers, run against the code

Two discount mechanisms sit on this store and they behave differently, so the quantity decision belongs before the coupon rather than after it.

Ten percent off ten vials is $4.28 a milligram. Fifty percent off one vial is $2.38. The tier route costs $427.50 to reach a per-milligram figure that is 80 percent worse than the single discounted vial, which is a strange way to spend four hundred dollars.

There is one place the tiers do something the code does not: at ten vials the cart passes $250 and shipping stops being charged. Ten discounted vials come to $237.50 and stay $12.50 short of the same threshold. That is a $15 saving bought with $190 of extra material, so it is not a saving, it is a much larger purchase wearing the costume of one.

Whether PEPTIDEDECK and a tier can be combined is not published by the vendor. Assume they cannot, budget on that basis, and check the subtotal in front of you rather than taking anyone's word for it.

What the assay does to the per-milligram figure

This is where a Selank listing becomes unusually checkable, and it is worth a minute.

Both certificates the vendor publishes for this product report a measured quantity, not just a purity percentage. The February 2026 certificate for lot 29-01260229 gives 12.29 mg in a vial labelled 10 mg. The June 2026 certificate for lot 29-05260628 gives 11.86 mg. Both vials were overfilled, and publishing the measurement at all is unusual enough to be worth crediting.

The honest reading is that these are measurements of two specific lots, not a guarantee about the vial that arrives at your door. Price on $2.38, treat an overfill as something you can verify afterwards by matching the lot number on the vial to the certificate, and be sceptical of any page that quotes $1.93 as though it were the advertised rate.

The nasal spray market is priced in a unit you cannot check

The other place Selank is sold to consumers is nootropic retailers listing a nasal spray, and the price comparison people try to make between the two formats does not work.

A vial is sold by mass. Ten milligrams, a stated purity, and a per-milligram figure you can calculate and hold against any other vial on the market. A spray is sold by bottle. The bottle contains a solution, the concentration is frequently stated loosely or not at all, and once the milligrams are invisible there is nothing left to divide. A $40 bottle and a $70 bottle cannot be ranked without a number neither listing gives you.

That is a structural point rather than a claim about quality. It is entirely possible for a spray to be good material. It is not possible to price it per milligram from the outside, and a per-milligram price is the only thing that makes two listings comparable. We are not publishing spray prices here because the ones circulating are not attached to a concentration we can verify.

The line that decides whether $23.75 was well spent

Price is the easiest thing to compare and the least informative, and on Selank there is a specific documented reason why.

FDA's page on bulk substances that may present significant safety risks, content current as of 22 April 2026, records that compounded drugs containing selank acetate may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities, and that the agency lacks important information about safety issues raised by selank acetate given to humans. Selank sits in that page's table of substances nominated for the compounding list and then withdrawn, not on any current category list.

Aggregation and peptide-related impurities is a testing question, and it converts into exactly two lines you look for on a certificate: an endotoxin result and a sterility result. Purity and identity tell you what the powder is. They do not tell you whether it is clean.

On Selank specifically, the answer depends on which lot you get, and that is the single most useful thing on this page. The February 2026 certificate from MZ Biolabs reports 99.32 percent purity by HPLC-UV and confirms identity by mass spectrometry against an expected monoisotopic mass of 751.43 Da, measured at 751.47 Da. It carries no endotoxin test, no sterility screen and no heavy metal panel. The June 2026 certificate from Kovera Labs, for the newer lot, reports 99.371 percent purity, an endotoxin safety screen at or below 0.5 EU/mL marked pass, a microbial sterility screen returning no growth, and arsenic, cadmium, lead and mercury all negative.

Same product, same vendor, four months apart, two different scopes of testing. So the useful instruction is not "check the COA", it is: read the lot number printed on the vial you received, find the certificate for that lot, and look for those two lines on it. A cheap vial whose certificate stops at purity is not the same purchase as a cheap vial whose certificate ran the endotoxin screen, and at $23.75 they cost the same.

Reconstitution arithmetic sits outside this page by design. What a vial becomes once water goes in is a separate question, and this one stops at the invoice.

If the code is the only thing you came for, the Selank coupon page covers where in the checkout it goes and what it does not stack with. The BPC-157 price breakdown runs the same per-milligram arithmetic on the closest comparable 10 mg research vial, the MOTS-c cost page takes the consumables problem further, and the NAD+ pricing page shows what happens when a compound is sold by the gram instead and the unit has to change with it.
