Pinealon 20mg Vial

Description

Listed as a laboratory reference material, the Pinealon 20mg vial is the Glu-Asp-Arg tripeptide from the Khavinson series, freeze dried and sealed under vacuum. The fill weight is 20 mg of net peptide content. The cake is white to off-white. Not for human or veterinary consumption, and neither a food nor a drug.

It belongs to the short peptide range catalogued under the Khavinson names, where the name is a supplier convention rather than a description of anything. The label on the Pinealon 20mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

Contents of the Pinealon 20mg vial

Everything that can honestly be said about the Pinealon 20mg vial before the certificate is opened is listed below.

Freeze dried powder, fill weight and price per milligram

The vial contains lyophilized powder. Water was taken out of the frozen solution under vacuum, which is gentler on a peptide than any form of heat and leaves behind a solid with very low moisture. That dryness is the whole point of the format. It is also why the certificate reports a water figure, since any moisture that stayed in the cake is moisture available to hydrolyse the peptide over time. Nothing about the Pinealon 20mg vial is sold by volume.

The arithmetic

Milligram content is the unit the Pinealon 20mg vial is sold in, because it is the only figure that makes two listings comparable. The per milligram figure is approximately $5.95 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 Pinealon 20mg 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

The document issued with each lot states the compound, the lot number, the date of analysis, the purity percentage from HPLC, the identity confirmation from mass spectrometry and the water content from titration, and it names the laboratory that produced those results. It is one page. Read all of it, because the figures a vendor chooses to quote are rarely the complete set. The certificate issued with the Pinealon 20mg 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 Pinealon 20mg 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

Identity confirmation is done by mass spectrometry against the expected molecular weight. The number that matters is the agreement between measured and calculated mass. It is the only line on the certificate that addresses the question of whether the label is accurate, and it is the reason a purity percentage on its own is not enough to describe a lot of synthetic peptide. The same methods are run on the Pinealon 20mg vial as on every other lot on this shelf, and formulae and expected masses for compounds of this class can be checked through PubChem at the NCBI.

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. 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 the Pinealon 20mg vial is the one the trade uses, and a trade name is not an identifier.

Storage is the usual practice for dry peptide material: sealed, refrigerated at 2 to 8 degrees Celsius over short intervals, frozen at minus 20 degrees Celsius or colder over long ones. Avoid moving it in and out of the cold repeatedly, because moisture condenses on cold glass. Keep the certificate with the Pinealon 20mg vial, since the lot number is the only thing joining the two.

Research use only, stated plainly

This is a laboratory reference material. It is not for human or veterinary consumption, it is not a food and it is not a drug. There is no dose on this page, no timing, no route, no site and no reconstitution method, and asking for any of them will not produce them. Bacteriostatic water, diluents and syringes are stocked separately and are not sold as a set with this item. No part of this page describes a use for this material in a person or an animal.

A research use only statement is not a legal strategy and is not treated as one here. Warning letters in this area turned on what the rest of the page said, not on whether a disclaimer was present. See research use only is not a legal strategy.

Withdrawn lots stay published alongside the rest rather than quietly disappearing. The page is a specification, and the specification is all of it. This item sits on the longevity shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
