Description
Sold as a laboratory reference material, the humanin 10mg vial is a twenty-four residue mitochondrial derived peptide. The fill weight is 10 mg of net peptide content. The powder is white to off-white. Purity comes from an assay of that specific lot rather than a figure carried over from the last one. Not for human or veterinary consumption.
The label on the humanin 10mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

Freeze dried powder, fill weight and price per milligram
Peptides are shipped dry for a simple reason: in solution they degrade, and nobody can control the temperature of a parcel in transit. Freeze drying removes the solvent under vacuum and leaves a solid with a low residual water figure, which the certificate states. The cake that results is physically fragile and can break loose and rattle. A broken cake is cosmetic. The number that matters is the fill weight. Nothing about the humanin 10mg vial is sold by volume.
Doing the division
Milligram content is the unit the humanin 10mg vial is sold in, because it is the only figure that makes two listings comparable. The quotient is close to $22.90 per milligram. Keep two things in view when you use it: the fill weight it was divided by, and the assay percentage from the certificate, because the second tells you how much of that fill is the named compound. Compare the humanin 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.
Reading the certificate for this lot
Certificates vary in layout and should not vary in content. Compound name, lot number, analysis date, HPLC purity with chromatogram, mass spectrometry identity, water content, laboratory identity and signature. Check the lot number against the vial, check the date, then read the figures. Documents that summarise results without showing the chromatogram are asking for more trust than they have earned. The certificate issued with the humanin 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 Stock is withdrawn from sale where the certificate for the humanin 10mg vial does not support the figures here. See how to read a certificate of analysis and check the lab before you check the numbers.
What the methods actually measure
The water figure on the certificate is a Karl Fischer result. It is there because moisture is both a stability problem and a weighing problem. The chemistry is a titration against iodine that consumes water stoichiometrically, which makes it a direct measurement instead of an estimate. The same methods are run on the humanin 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 FDA drugs section.
Naming, abbreviations and storage
Expect the same compound under several names. Transliteration adds variant spellings on top of that, which is why sequence and measured mass, not the title of a listing, are the identifiers that hold. Several abbreviations on this shelf unpack into descriptions of activity. They are not unpacked here, and where a compound cannot be described without that, only its measurable properties are described. The catalogue name carried by the humanin 10mg 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 humanin 10mg vial, since the lot number is the only thing joining the two.
Research use only: this vial is a reagent
Sold to qualified purchasers for laboratory research only. Not for human or veterinary use. The page carries no dosing information, no protocol, no administration instructions and no account of physiological activity, because publishing any of those would be describing a use this material is not sold for. We will not supply them privately either. 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.
Lots that failed their own stated figures are kept rather than deleted, which is the point of an archive as against a highlight reel. This item sits on the longevity shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
