Semax and Selank Blend 10mg Vial

Description

The Semax and Selank blend 10mg vial is two heptapeptides co-lyophilized in one vial, supplied as lyophilized powder with the purity figure for the lot published beside it. The vial holds 10 mg in total, made up of 5 mg of Semax and 5 mg of Selank. The powder is white to off-white and the vial is sealed under vacuum. It is sold as a laboratory reference material and is not for human or veterinary consumption.

The label on the Semax and Selank blend 10mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

What is in the Semax and Selank blend 10mg vial

The table below is the standing description of the Semax and Selank blend 10mg vial. Measured values live on the lot certificate.

Why it is a powder, and what a milligram of the Semax and Selank blend 10mg vial costs

Freeze drying is the standard way to supply a peptide, and what it does is simple enough. The frozen solution is held under vacuum until the ice has left as vapour, which strips out the solvent without cooking the molecule. The result is a dry, porous solid with a measured moisture content. Appearance is not a specification. Fill weight, purity and water content are the specifications. Nothing about the Semax and Selank blend 10mg vial is sold by volume.

Doing the division

Milligram content is the unit the Semax and Selank blend 10mg vial is sold in, because it is the only figure that makes two listings comparable. That is around $12.90 per milligram on the price as listed. Milligram content is the unit the whole comparison should run on, and anything else, a per vial price or a per order price, moves with packaging rather than with content. Compare the Semax and Selank blend 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.

The documentation that comes with the Semax and Selank blend 10mg vial

Read the certificate from the top and check the identifiers before the numbers. Lot number first, matched against the vial. Date of analysis next, because an old date on a new lot is a sign the document has been recycled. Then purity, then the mass spectrometry comparison, then water content, then the signature and the name of the laboratory. A sheet missing the lot number is not a certificate, it is a leaflet. The certificate issued with the Semax and Selank blend 10mg vial is specific to the lot and not to the product line.

Testing is contracted out to a laboratory with no ownership tie to the seller. It is a weaker guarantee than people sometimes assume and a stronger one than in house assay, for the plain reason that the people producing the number are not the people selling the vial. Stock is withdrawn from sale where the certificate for the Semax and Selank blend 10mg vial does not support the figures here. See how to read a certificate of analysis and why we publish the batch that failed.

Purity, identity and moisture are three different measurements

Purity figures here come from liquid chromatography, which separates by affinity for a stationary phase. Each component eluting from the column registers as a peak, and purity is computed as the fraction of total peak area belonging to the target. One consequence follows: the percentage describes composition, so it tells you how much of the detected material is the right molecule, not how many milligrams are in the glass. The same methods are run on the Semax and Selank blend 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.

Naming, abbreviations and storage

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. Where an abbreviation expands into a statement about what a compound does, the abbreviation is what appears here, in the title, the web address, the image description and the text alike. The catalogue name carried by the Semax and Selank blend 10mg vial is the one the trade uses, and a trade name is not an identifier.

Handling notes are short. Sealed, dry, cold and dark, at 2 to 8 degrees Celsius for the short term and minus 20 degrees Celsius or below for anything longer. The stability window for the lot is printed on this listing. Keep the certificate with the vial, since the lot number is the only thing joining the two.

Research use only: this vial is a reagent

Research use only, not for human or veterinary consumption. That sentence is a description of what is being sold and not a disclaimer appended to something else. There is accordingly no dose, no cycle, no route of administration and no reconstitution guidance anywhere on this page, and the omission is the policy rather than a gap in the copy. 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.

The limits of that sentence need stating. A research use only line describes what is sold, it is not a shield, and the enforcement record shows whole product pages being read rather than disclaimers alone. See research use only is not a legal strategy.

Every figure quoted here comes from the document linked above, and older certificates are kept rather than retired. That is the whole of the claim being made. This item sits on the nootropic shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
