IGF-1 LR3 1mg Vial

Description

Sold as a laboratory reference material, the IGF-1 LR3 1mg vial is the Long R3 analog of IGF-1. The fill weight is 1 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 same material is catalogued elsewhere as Long R3 IGF-1. It is lyophilized with mannitol as the bulking agent, so gross contents and net peptide content diverge further here than in most vials on this shelf. The label on the IGF-1 LR3 1mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.

The IGF-1 LR3 1mg vial, specified

The table below is the standing description of the IGF-1 LR3 1mg vial. Measured values live on the lot certificate.

The format, the fill weight and the milligram arithmetic

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 IGF-1 LR3 1mg vial is sold by volume.

How the per milligram figure is worked out

Milligram content is the unit the IGF-1 LR3 1mg vial is sold in, because it is the only figure that makes two listings comparable. Dividing the listed price by the fill weight gives about $169.00 per milligram. That figure is printed under the price for a reason: a bigger vial almost always looks more expensive and is almost always cheaper per milligram, and the headline price hides that completely. Compare the IGF-1 LR3 1mg 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

Each lot has its own certificate and the document is tied to the lot number printed on the vial label. On it you will find the analysis date, the HPLC purity figure together with the chromatogram, the mass spectrometry identity comparison, the Karl Fischer water result, and the issuing laboratory. Those seven items are the specification. Everything else on a vendor page is commentary. The certificate issued with the IGF-1 LR3 1mg vial is specific to the lot and not to the product line.

Testing is contracted out to a laboratory with no ownership tie to the seller. It is a weaker guarantee than people sometimes assume and a stronger one than in house assay, for the plain reason that the people producing the number are not the people selling the vial. Stock is withdrawn from sale where the certificate for the IGF-1 LR3 1mg 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

Mass spectrometry confirms what the compound is. The sample is ionised and the instrument measures mass to charge, which is then checked against the expected value for the sequence. Purity and identity are different properties: chromatography says how much of the material is the main component, and the spectrum says what that component is. Both appear on the certificate. The same methods are run on the IGF-1 LR3 1mg 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 IGF-1 LR3 1mg vial

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. 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 IGF-1 LR3 1mg vial is the one the trade uses, and a trade name is not an identifier.

Keep the vial sealed, cold and dark. Lyophilized material of this class is normally held at 2 to 8 degrees Celsius for short periods and at minus 20 degrees Celsius or below for longer ones, and the window for the lot is on this listing. Keep the certificate with the IGF-1 LR3 1mg vial, since the lot number is the only thing joining the two.

Research use only, and what this page will not tell you

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.

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.

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