Pal-GHK 200mg Vial

Description

The Pal-GHK 200mg vial is the glycyl-histidyl-lysine tripeptide carrying a palmitoyl group at the N terminus, INCI name Palmitoyl Tripeptide-1, supplied as lyophilized powder with the purity figure for the lot published beside it. The fill weight is 200 mg of net peptide content. 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 same material is catalogued elsewhere as Palmitoyl Tripeptide-1. Unlike the copper complex of the same tripeptide, this form is not blue, because there is no copper in it. The label on the Pal-GHK 200mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

Contents of the Pal-GHK 200mg vial

Everything that can honestly be said about the Pal-GHK 200mg vial before the certificate is opened is listed below.

Why it is a powder, and what a milligram of the Pal-GHK 200mg vial costs

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 Pal-GHK 200mg vial is sold by volume.

The arithmetic

Milligram content is the unit the Pal-GHK 200mg vial is sold in, because it is the only figure that makes two listings comparable. At the price shown, that works out at roughly $0.99 per milligram. The sum is the whole price divided by the milligrams in the vial, and it is the only comparison between two listings that survives contact with different vial sizes. Prices move, so recompute it rather than quoting this sentence back at anybody. Compare the Pal-GHK 200mg 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

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 Pal-GHK 200mg vial is specific to the lot and not to the product line.

The laboratory that runs the assay has no ownership connection to this company. That arrangement is not a seal of approval and it does not make the figures infallible, but it does remove the obvious conflict of interest in a vendor grading its own stock. Stock is withdrawn from sale where the certificate for the Pal-GHK 200mg 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

Purity is reported by high performance liquid chromatography. A column separates the components by how strongly each sticks to the packing, and the detector output is a chromatogram of peaks. The purity figure is the area of the main peak divided by the area of every peak. It is a statement about proportion rather than absolute mass, and it belongs to the lot that was assayed. The same methods are run on the Pal-GHK 200mg 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.

Catalogue names 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 Pal-GHK 200mg 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 Pal-GHK 200mg vial, since the lot number is the only thing joining the two.

What this listing refuses to say

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.

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.

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