Semax Price: $30 a Vial, and No Pharmacy Sets a Second One

The Semax price on the listing we link is $59.99 for a 10 mg lyophilised vial, and the code PEPTIDEDECK takes that to $30.00. Ten milligrams on the label divides into $3.00 per milligram, and that unit figure is the one worth carrying into every comparison you make after this page. Both numbers were read off the listing on 21 August 2026.

Per milligram is the unit that survives a change of packaging, and here it does more work than usual. Vial sizes are not standardised across research suppliers, so two listings at similar prices can differ by half on the material inside. Much of the consumer market also sells Semax as a nasal spray priced per bottle, and many of those listings never state how much peptide the bottle holds, which leaves nothing to divide by.

What the $30.00 buys is 10 mg of a synthetic heptapeptide: seven residues in the order Met-Glu-His-Phe-Pro-Gly-Pro, the ACTH(4-7) fragment with a Pro-Gly-Pro tail added to slow enzymatic breakdown. PubChem lists it as CID 9811102, formula C37H51N9O10S, molecular weight 813.9. It is regularly described as a tuftsin analogue and it is not one. That description belongs to Selank, the other Russian heptapeptide, which is a different molecule with a different sequence, and the two get swapped constantly by pages selling both.

One supplier is linked on this page and we earn a commission if you buy through it, which our affiliate disclosure sets out in full. It is why the list price is printed here next to the discounted one, and why the section on what $30.00 does not buy has not been trimmed.

How much does Semax cost becomes a different question once quantity is involved, and the listing publishes its tiers rather than hinting at them. Three vials take 3 percent off the list price, five take 5 percent and ten take 10 percent. On a $59.99 vial that is $1.80, $3.00 and $6.00 off each one, so $58.19, $56.99 and $53.99 apiece.

The order totals are $174.57 for three, $284.95 for five and $539.91 for ten. Free shipping starts once an order passes $250, so five vials clear that line and three do not, which belongs in the comparison before you call a tier the better deal.

The important thing about those tiers is that every one of them is a worse unit price than the code. Ten percent off list works out at $5.40 per milligram. The code works out at $3.00 per milligram. Both discounts come off the same $59.99 list price, and whether they combine is settled by the checkout rather than by any published policy, so we are not going to print a stacked figure we cannot point to a source for. Build the cart both ways and compare the totals on screen before you enter a card.

There is one real argument for buying more than one vial and it is not the money. A certificate is batch specific, so several vials from a single batch are covered by one document you have already read, where vials bought across a year are several batches and several documents, and the later ones are not obliged to carry the same tests. Set that against the whole order being exposed on a substance with no approved use and no return path beyond the vendor's policy.

On the drugs this site usually covers there are at least three prices for one molecule: a manufacturer list price, a cash price somebody negotiated, and whatever a plan leaves the patient holding. That structure is the entire subject of our guide to what GLP-1 care actually costs. Semax has one price, from one kind of seller.

The reason is regulatory rather than commercial. Semax holds no FDA approval for any indication, so there is no approved product, no national drug code and no formulary position for it to occupy. The compounded route is closed as well. A pharmacy compounding under section 503A of the Federal Food, Drug and Cosmetic Act may work from a bulk drug substance only if that substance meets a United States Pharmacopeia or National Formulary monograph, is a component of an FDA-approved drug product, or appears on FDA's 503A bulks list. Semax satisfies none of the three.

The bulks-list part is where competing pages go wrong, so it is worth stating precisely. Semax was nominated, was placed in category 2 under FDA's interim policies while the agency evaluated it, and the nomination was then withdrawn. It appears on no current category list at all. Today's category 2 holds six substances, which are cesium chloride, domperidone, germanium sesquioxide, ibutamoren mesylate, kisspeptin-10 and quinacrine hydrochloride for intrauterine administration, and Semax is not among them. Nominated and withdrawn is the accurate description. Category 2 is stale, and banned is a word nobody at the agency used.

For a price comparison the consequence is total. No pharmacy can lawfully prepare it, so there is no compounded prescription to price and no insurer to appeal to. Compare that with our NAD+ price breakdown, where a clinic channel genuinely exists and the question is how far a drip session sits above the raw material. For Semax the second column is empty, and that is the market rather than an omission.

Search for this compound and a large share of what comes back is nasal spray sold by nootropic retailers and priced per bottle. Those listings and this one cannot be ranked against each other on price, and the reason is not that one of them is dearer.

A per bottle price with no stated peptide content cannot be converted into a per milligram figure. You would be setting $3.00 per milligram against a number with no denominator. Where a spray listing states total content and fill volume, divide and compare. Where it does not, the two are not comparable, and a bottle that looks cheaper may hold a fraction of the material.

The formats also carry different obligations, which our page on buying Selank as a nasal spray works through for the neighbouring compound. A sealed powder and a liquid sitting in a pump bottle raise different questions about sterility, preservatives and shelf life. Pricing them as the same product picks wrong reliably.

Part of what separates one listing from another is lab work that never appears as a line item.

Ascension publishes a four page combined certificate of analysis for Semax batch 30-05260628. Purity is reported at 99.886 percent against a stated specification of greater than 98 percent. Bacterial endotoxin is tested by kinetic chromogenic LAL assay to USP Chapter 85, against an E. coli O111:B4 standard across a detection range of 0.01 to 1.0 EU/mL, reporting under 0.20 EU/mL against a 0.5 EU/mL acceptance limit. A microbial sterility screen reports no growth. Labelled quantity is 10 mg, lyophilised.

An HPLC purity run is routine and nearly every seller in this market publishes one. Endotoxin and sterility are separate assays with their own standards, consumables and turnaround, charged per batch, and they are the tests most listings quietly skip. What the Semax price buys is not that panel, because the same vendor's June Selank batch carries it too and its February documents for both compounds carry purity and identity only. Which tests you get is a batch question rather than a product question, so open every certificate on a product page instead of only the one that is a clickable link.

So when you set $3.00 per milligram against a cheaper listing, the useful question is which batch it is quoting and what that batch's certificate covers. That is a fairer reading of a price gap than assuming the dearer vendor is simply charging more. Our Selank price breakdown runs the same arithmetic on the neighbouring compound and reaches the same conclusion about which number matters.

Here is the half of the page a vendor would not write. Everything above is a manufacturing question, and manufacturing is not the thing FDA has raised about this compound.

The agency's position, quoted in full from its page on bulk drug substances that may present significant safety risks: "Compounded drugs containing semax (heptapeptide) may pose risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities. FDA has no, or limited, safety-related information for proposed routes of administration. Therefore, the agency lacks sufficient information to know whether the drug would cause harm if administered to humans."

Read that closely and you can see exactly how much of the gap a certificate closes. Aggregation and peptide-related impurities are manufacturing and handling problems, and testing is the right instrument for them. A batch assayed for purity, screened for endotoxin and showing no microbial growth has addressed a real part of what the agency named. What no certificate produces is human safety data, and the last sentence of that quotation is about human safety data. A clean result on batch 30-05260628 says the batch was well made. It says nothing about what the compound does in a person. Both halves are true at once.

The other thing $30.00 does not buy is recourse. No pharmacist checks the order, no prescriber has seen you, no state board has jurisdiction and no insurer can be appealed to. What you have is the vendor's written policy and a chargeback through your card issuer, which is a reason to pay by card and keep the order summary and the batch number together.

$3.00 per milligram is the figure to write down. It survives a change of vial size and it exposes the difference between a genuine reduction and a rearranged list price. Everything else here moves: the tiers, the shipping threshold, the batch and the certificate attached to it.

The second thing to keep is the absence. There is no prescription price for Semax anywhere in the United States, so a page quoting you a clinic or pharmacy figure has invented it, and noticing that is a better test of a source than anything it says about the compound.
