Description
Sold as a laboratory reference material, the Decapeptide-12 200mg vial is a ten residue synthetic peptide carrying the INCI name Decapeptide-12. The fill weight is 200 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 Decapeptide-12 200mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

Why it is a powder, and what a milligram of the Decapeptide-12 200mg vial costs
Lyophilized means the material was frozen and then dried under reduced pressure, so the ice sublimed straight to vapour. Heat drying would damage the sequence, and a liquid product would arrive degraded. The finished cake is porous and light. It can look like a wafer, a crust, or almost nothing at all in a small fill, and that variation is normal rather than a defect. Nothing about the Decapeptide-12 200mg vial is sold by volume.
Doing the division
Milligram content is the unit the Decapeptide-12 200mg vial is sold in, because it is the only figure that makes two listings comparable. At the listed price this comes to something like $1.34 per milligram. It is printed under the price rather than buried, because the alternative is a page where a large vial and a small one cannot be compared at all. Compare the Decapeptide-12 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.
Reading the certificate for this lot
What a certificate of analysis should contain is not mysterious. The compound as named. The lot. When it was tested. The purity figure and the chromatogram it came from. The observed mass against the calculated mass. The water content. Who did the testing. Where any of those are absent, the document is describing less than it appears to describe. The certificate issued with the Decapeptide-12 200mg 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 Stock is withdrawn from sale where the certificate for the Decapeptide-12 200mg vial does not support the figures here. See how to read a certificate of analysis and check the lab before you check the numbers.
Purity, identity and moisture are three different measurements
The certificate carries a mass spectrometry result alongside the chromatography. Measured mass is set against the mass calculated from the sequence, and agreement between the two is the evidence of identity. It is a short line on the page and the most important one, because every other figure on the sheet describes a material that the spectrum has to name first. The same methods are run on the Decapeptide-12 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 FDA drugs section.
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. 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 Decapeptide-12 200mg vial is the one the trade uses, and a trade name is not an identifier.
Sealed, cold, dark and dry. Short term storage at refrigerator temperature and long term storage at minus 20 degrees Celsius or colder are the standard conditions for lyophilized peptide material of this kind. 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
Offered for laboratory research use by qualified purchasers and for nothing else. Not for human or veterinary consumption, not a food, not a drug. No physiological description is published, no dosing figure, no administration protocol and no reconstitution procedure, and requests for them are declined rather than answered quietly. 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.
The certificate travels with the lot number and is linked above. Nothing in this description goes further than that document goes. This item sits on the cosmetic peptide shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
