Description
Listed as a laboratory reference material, the Semax 10mg vial is a heptapeptide derived from the ACTH 4-10 sequence, freeze dried and sealed under vacuum. Fill weights of 10 mg and 25 mg are offered here, chosen before you order. The cake is white to off-white. Not for human or veterinary consumption, and neither a food nor a drug.
The label on the Semax 10mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.
What the Semax 10mg vial is
The table below is the standing description of the Semax 10mg vial. Measured values live on the lot certificate.

| Form | Lyophilized, white to off-white, sealed under vacuum |
| Sequence length | Seven residues |
| Purity | HPLC, percent of total peak area |
| Identity | Mass spectrometry against expected mass |
| Water | Karl Fischer titration, percent by weight |

| Price basis | Per milligram figure shown against each strength |
| Supplied for | Laboratory research use only, not for human or veterinary consumption |
Lyophilized powder, and the price per milligram of the Semax 10mg vial
Lyophilized means the material was frozen and then dried under reduced pressure, so the ice sublimed straight to vapour. Heat drying would damage the sequence, and a liquid product would arrive degraded. The finished cake is porous and light. It can look like a wafer, a crust, or almost nothing at all in a small fill, and that variation is normal rather than a defect. Nothing about the Semax 10mg vial is sold by volume.
Doing the division
Milligram content is the unit the Semax 10mg vial is sold in, because it is the only figure that makes two listings comparable. This listing has more than one strength, so the arithmetic has to be done per option: take the price of the option and divide it by its milligram content. The result is printed under each price. It is the number that makes two vial sizes, and two vendors, comparable at all. Compare the Semax 10mg vial on that basis rather than on the price of the glass. The case is made at greater length in why price per milligram beats the price on the bottle.
What the certificate of analysis reports
Each lot has its own certificate and the document is tied to the lot number printed on the vial label. On it you will find the analysis date, the HPLC purity figure together with the chromatogram, the mass spectrometry identity comparison, the Karl Fischer water result, and the issuing laboratory. Those seven items are the specification. Everything else on a vendor page is commentary. The certificate issued with the Semax 10mg vial is specific to the lot and not to the product line.
Assays are run by an outside contract laboratory rather than in house. Independence of that kind matters, and it has a limit: the figure still depends on the sample that was submitted, which is why lot by lot testing rather than periodic testing is the part that matters. Stock is withdrawn from sale where the certificate for the Semax 10mg vial does not support the figures here. See how to read a certificate of analysis and why we publish the batch that failed.
What the methods actually measure
Identity rests on the mass spectrum. An ionised sample is measured for mass to charge, and the figure is compared with the calculated mass of the named sequence. Keep it separate from the purity line in your head. One tells you the proportion of the main component, the other tells you whether the main component is the molecule you ordered. The same methods are run on the Semax 10mg vial as on every other lot on this shelf, and formulae and expected masses for compounds of this class can be checked through the European Medicines Agency.
Why the name is inconsistent, and how to store the Semax 10mg vial
One compound, several names, is the normal condition here. Internal codes outlive the laboratories that issued them, INCI numbers get reassigned, and nothing in a product title resolves any of it. Some names in this category spell out an intended effect once expanded. Those stay abbreviated, because writing them out would turn a catalogue entry into an assertion about biological activity. The catalogue name carried by this vial is the one the trade uses, and a trade name is not an identifier.
Dry material is forgiving within limits. Refrigeration at 2 to 8 degrees Celsius suits short storage and minus 20 degrees Celsius or lower suits long storage, with light and humidity the two things to keep away from the vial. Keep the certificate with the vial, since the lot number is the only thing joining the two.
Research use only, stated plainly
The material is a reagent. It is not a medicine, not a supplement, not for human or veterinary consumption, and it is sold for in vitro and laboratory work by purchasers qualified to handle it. You will not find a dose, a schedule, an injection site or a mixing instruction here. Those belong to a use that is not offered. No part of this page describes a use for this material in a person or an animal. Bacteriostatic water, sterile diluents and syringes are stocked separately rather than sold as a set with the vial.
Two things are true at once. This is sold as a laboratory reference material, and that sentence on its own settles nothing, because a page that describes effects, timing or quantities for a person is describing a use whatever the footer says. See research use only is not a legal strategy.
Read the certificate, check the lot number against the vial, and the listing has told you everything it can tell you. This item sits on the nootropic shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
