Buy Selank Online: $23.75 in the Cart, 10 mg in the Box
Buy Selank online end to end: what the cart does to $47.50, what payment method leaves you recourse, what arrives, and the lot code check to run before storage.

Buy Selank online and the transaction has six stages, only one of which is a price. The cart takes $47.50 to $23.75. The rest of it decides whether the vial that arrives is the vial the certificate describes, and no discount code has anything to say about that.
This page follows the sequence rather than the criteria. What the checkout does to the number, which payment method leaves you a route back, how a lyophilised peptide travels, what is in the box, and the one string of characters to check before anything goes in a freezer. Selank is a synthetic heptapeptide with no FDA approval, so every step here happens outside the pharmacy system and none of the consumer protections that system carries apply.
The listing the sequence is traced against is the one costed here.

Buy Selank online: the sequence from cart to cold storage
Six stages, and the risk is distributed unevenly across them. Most buyers spend their attention on stage one and none on stage five, which is backwards.
| Stage | What happens | What can go wrong |
|---|---|---|
| 1. Cart | $47.50 becomes $23.75 with the code, or a tier applies to the list price | Assuming a code and a tier stack when nothing documents that they do |
| 2. Payment | Card, or an alternative rail with different recourse | Paying by a method with no chargeback route |
| 3. Dispatch | Same-day before 2pm CST from domestic stock | A processing window instead of a cut-off, which often means drop-shipping |
| 4. Transit | A sealed vial of dry powder at ambient temperature | Nothing much, for a lyophilised peptide. This stage is the forgiving one |
| 5. Arrival | Lot code on the vial checked against the published certificate | Skipping it, which silently invalidates every number you relied on |
| 6. Storage | Dry powder stored cold and dark, unopened | Reconstituting immediately because the box arrived |
Stage five is where the money you saved in stage one either means something or does not. A price per milligram computed against a certificate that describes a different batch is a number without a referent.
The cart: what $47.50 becomes, and what the tiers do instead
The listing shows $60.00 struck through to $47.50 for a 10 mg vial. The code PEPTIDEDECK takes 50% off that, landing at $23.75, which is $2.38 per milligram against $4.75 at list. Separately, quantity tiers discount the list price at three, five and ten vials.
| Order | Basis | Per vial | Total | Cost per mg |
|---|---|---|---|---|
| One vial | PEPTIDEDECK | $23.75 | $23.75 | $2.38 |
| One vial | List | $47.50 | $47.50 | $4.75 |
| Three vials | 3% tier | $46.08 | $138.23 | $4.61 |
| Five vials | 5% tier | $45.13 | $225.63 | $4.51 |
| Ten vials | 10% tier | $42.75 | $427.50 | $4.28 |
The two mechanisms work on different bases, which is why the ladder never catches up. The best tier is $4.28 per milligram, 80% above what the code does to a single vial, and reaching it means committing $427.50 for 100 mg. Whether a tier and the code combine in the same cart is not documented anywhere we can point to, so treat the checkout total as the only authority and do not plan an order around stacking. The same arithmetic on a different compound is worked through in our MOTS-c coupon breakdown, where a single-vial code likewise beats every bulk rung.
One threshold interacts with all of this. Free shipping starts at $250. A five-vial tier order at $225.63 misses it by $24.37, a ten-vial order clears it comfortably, and a single vial at $23.75 is not close. Whether the threshold reads the subtotal before or after a discount is a cart rule, and the cart is the only place that can settle it.
Payment: what each rail leaves you when something goes wrong
Payment method is the stage buyers think about least and the one that determines what happens if the parcel never arrives. Research-chemical sellers accept a narrower set of rails than ordinary retailers, for reasons that have nothing to do with the specific seller.
- Card. The only rail with a real dispute mechanism behind it. Card networks and issuers can reverse a charge, though a research-chemical purchase is a weaker case than a consumer one and the outcome is not guaranteed.
- Bank transfer or ACH. Cheap for the seller, final for you. Once it has cleared there is no protocol-level way to claw it back.
- Cryptocurrency. Irreversible by design. A discount offered for paying this way is a discount priced against the recourse you are giving up, and it is worth deciding whether the trade is worth it before the discount tempts you.
- Third-party wallets. Recourse depends entirely on that wallet's own policy for the merchant category, and research chemicals are commonly excluded.
None of this indicts a seller who accepts only certain rails. Payment processors decline entire merchant categories regardless of individual conduct. It does mean the recourse question should be answered before checkout rather than after a tracking number goes quiet. The stage-by-stage version for a compound with the same purchasing profile is in our BPC-157 online purchase walkthrough.
Dispatch and transit: the forgiving stage
Lyophilised peptide is the easy part of this transaction. Freeze-drying removes the water that hydrolysis and microbial growth both need, which is why dry Selank ships at ambient temperature without a cold chain and why the transit stage carries less risk than the purchase stage.
Two operational signals separate a seller holding stock from an intermediary who orders your vial after your money clears. A dispatch cut-off, meaning same-day before 2pm CST, is a commitment against a clock. Ships within one to three business days is a description of a queue. And a stated domestic origin removes customs from the transaction entirely: no declared value, no brokerage, no seizure, and a return path that physically exists.
That second point is worth more than the price difference that usually motivates buying abroad. A seized international parcel is a total loss with no recourse on any payment rail, and the sticker saving that justified the risk was computed per vial rather than per landed milligram. The comparison in our NAD+ online purchase guide runs the same shipping-origin argument on a compound where the shipping weight is a hundred times larger.
On arrival: check the lot code before anything else
The box contains a sealed glass vial of white lyophilised powder, a coloured cap and crimp, and a printed lot code. That code is the first thing to read, because every other number you have relied on is attached to it.
Ascension publishes two third-party certificates against this listing, and they cover different tests. This is the single most consequential thing to know about buying this compound.
| Reported | Lot 29-01260229, MZ Biolabs | Lot 29-05260628, Kovera Labs |
|---|---|---|
| Purity | 99.32% | 99.371% |
| Quantity measured | 12.29 mg | 11.86 mg |
| Identity | 751.47 Da against 751.43 expected | Confirmed by LC-MS |
| Bacterial endotoxin | Not on the document | Below 0.20 EU/mL by kinetic chromogenic LAL to USP Chapter 85 |
| Sterility screen | Not on the document | No growth over two days at 30 to 35 C |
Read the row that matches your vial, not the row you would prefer, and read the sterility result at its stated strength: the report calls that method a preliminary screen and notes that full compendial testing may be required for regulatory compliance. The reason the endotoxin line matters on this compound in particular is that FDA has stated that compounded drugs containing selank acetate may pose a risk for immunogenicity for certain routes of administration, due to the potential for aggregation and peptide-related impurities, and that it lacks important information about safety issues raised by administration to humans. Purity does not answer that. Endotoxin and microbial testing begin to, and a certificate that omits them has left the question open for your batch regardless of what a different batch showed.
If the code on the vial matches nothing published, that is an email to the seller before the vial goes anywhere. It is also the moment to note that dry powder unopened is the most storable state this product will ever be in. Our peptide storage guide covers both the dry and reconstituted cases.
Opening it: the volume sets the resolution, not the cost
Laboratory handling arithmetic follows, and nothing below is a protocol or a suggestion about use in a person. It is the conversion from a purchase into a concentration.
| Diluent added | Concentration | Mass in one U-100 unit | Units in the vial | Cost per unit at $23.75 |
|---|---|---|---|---|
| 1 mL | 10 mg/mL | 100 mcg | 100 | $0.24 |
| 2 mL | 5 mg/mL | 50 mcg | 200 | $0.12 |
| 3 mL | 3.33 mg/mL | 33 mcg | 300 | $0.08 |
| 5 mL | 2 mg/mL | 20 mcg | 500 | $0.05 |
Cost per unit falls as you add water, and nothing has become cheaper. Half a milligram costs $1.19 at the code rate in every row of that table, because dilution changes how finely the barrel can resolve a mass and changes nothing about what the mass cost. Cost per unit only compares across two vials when the concentrations match, which they almost never do.
One caveat specific to this product. If your vial is the lot that assayed at 12.29 mg, then adding 2 mL gives 6.15 mg/mL rather than 5, and a volume calculated from the label carries about 23% more mass than the label maths implies. That is a good argument for reading your own certificate and a bad argument for treating an overfill as a feature, since nothing on the listing promises one. The Selank calculator takes any volume, and the Selank price page divides the purchase every way that changes a decision.
Frequently Asked Questions
Is it legal to buy Selank online in the US?expand_more
It is sold openly as research material, which is a different transaction from buying a medicine. There is no FDA-approved Selank product, so no pharmacy can dispense it, and the substance appears in no category of the 503A bulk drug substances list, so no compounding route exists either. Research-use sale carries no approval and no implication of suitability for use in a person.
What is the cheapest way to order Selank?expand_more
A single vial with the code. $47.50 becomes $23.75, which is $2.38 per milligram. The quantity tiers discount the list price instead, landing at $4.61, $4.51 and $4.28 per milligram for three, five and ten vials, all of them well above the single-vial code rate. Stacking a tier with the code is not documented, so the checkout total is the only figure worth trusting.
How is Selank shipped, and does it need cold packs?expand_more
As sealed lyophilised powder at ambient temperature. Freeze-drying removes the water that hydrolysis and microbial growth both require, so a dry vial tolerates transit far better than any solution would. Cold storage matters after the box arrives, and matters much more once the powder has met water. A pre-mixed nasal spray is the format where the cold chain becomes a real transit question.
What should I check the moment the vial arrives?expand_more
The lot code, against the published certificate. The two documents on this listing report different scopes: lot 29-01260229 covers purity, identity and a measured 12.29 mg with no endotoxin or sterility test, while lot 29-05260628 adds endotoxin below 0.20 EU/mL by LAL, a sterility screen with no growth and negative heavy metals. Also check the seal, the cap and that the powder is intact rather than collapsed or discoloured.
Which payment method is safest for a Selank purchase?expand_more
A card, because it is the only common rail with a dispute mechanism behind it. Bank transfers and cryptocurrency are final once sent, and a discount offered for using them is effectively priced against the recourse you give up. Third-party wallets vary, and research chemicals are a commonly excluded merchant category, so check the policy rather than assuming coverage.
Does buying more vials online lower the price per milligram much?expand_more
Barely. Ten vials at the 10% tier is $427.50 for 100 mg, or $4.28 per milligram, against $2.38 for one vial with the code. The tiers discount the list price while the code discounts a single vial, so a 10% reduction is competing against a 50% one. Free shipping starting at $250 is the one genuine advantage of a larger order, and a five-vial tier order misses that threshold by $24.37.
