FOXO4-DRI 10mg Vial

Description

The FOXO4-DRI 10mg vial is a laboratory reference material and nothing else. The compound is a retro inverso construct built from D amino acids. The fill weight is 10 mg of net peptide content. Appearance is white to off-white, sealed under vacuum, with the lot number printed on the label. It is not a food, not a drug, and not for human or veterinary consumption.

The same material is catalogued elsewhere as proxofim. Retro inverso means the residue order is reversed and the residues themselves are the D enantiomers, which is a structural fact and shows up in the mass and the optical properties rather than in a catalogue name. The label on the FOXO4-DRI 10mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

The FOXO4-DRI 10mg vial, specified

The table below is the standing description of the FOXO4-DRI 10mg vial. Measured values live on the lot certificate.

The format, the fill weight and the milligram arithmetic

Freeze drying is how a peptide reaches you stable at ambient temperature. The solution is frozen solid, then the ice is pulled off under vacuum instead of being melted, so the water never passes through a liquid phase on the way out. What is left behind is a porous cake. In the vial it may sit as a flat disc, a loose dust, or a thin film part way up the glass. None of those appearances says anything about the contents. Fill weight and the assay figure do. Nothing about the FOXO4-DRI 10mg vial is sold by volume.

The arithmetic

Milligram content is the unit the FOXO4-DRI 10mg vial is sold in, because it is the only figure that makes two listings comparable. The per milligram figure is approximately $36.90 at the current price. It is the honest basis for comparison because it cancels out vial size. A vendor quoting only a bottle price is asking to be compared on the wrong axis. Compare the FOXO4-DRI 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 FOXO4-DRI 10mg vial

A certificate of analysis is a short document and every line on it is doing work. There is a product name and a lot number, and the lot number has to match the label on the vial in your hand. There is a date of analysis. There is the HPLC purity figure with the chromatogram behind it. There is a mass spectrometry result against the expected mass. There is a water content percentage. There is the name of the laboratory that ran the work. The certificate issued with the FOXO4-DRI 10mg vial is specific to the lot and not to the product line.

The assay is performed by a contract laboratory unconnected to this business. Any lot that comes back below its stated milligram content is pulled from sale, and the certificate stays published on the results page with everything else instead of quietly disappearing. Stock is withdrawn from sale where the certificate for the FOXO4-DRI 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

Assay purity is measured chromatographically. The lot is dissolved, loaded onto a column that resolves the target sequence away from its synthesis relatives, and the detector trace is integrated. The reported percentage is peak area of the main component over total peak area. Figures are published as the instrument returned them rather than rounded up to a round marketing number. The same methods are run on the FOXO4-DRI 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 NCBI chemistry and literature databases.

Names, abbreviations and how to keep the FOXO4-DRI 10mg vial

Abbreviations here are inherited rather than designed. They come from the groups that first made a compound, from ingredient registers, from development programmes and from vendors, so two listings can look different and be identical. 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 FOXO4-DRI 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 vial, since the lot number is the only thing joining the two.

What this listing refuses to say

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.

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.

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 longevity shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
