Description
The tesamorelin 10mg vial is supplied as a synthetic GHRH analog, freeze dried and sealed. Fill weights of 10 mg and 5 mg and 2 mg are offered here, chosen before you order. The cake is white to off-white. Every figure quoted on this page comes from the certificate issued against the lot number on the vial. For laboratory research use, and not for human or veterinary consumption.
The label on the tesamorelin 10mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.
What the tesamorelin 10mg vial is
Everything that can honestly be said about the tesamorelin 10mg vial before the certificate is opened is listed below.

Why it is a powder, and what a milligram of the tesamorelin 10mg vial costs
The powder is lyophilized, which means the water was removed by sublimation after the solution had been frozen. Peptides tolerate that far better than they tolerate heat. The product is a dry solid holding very little moisture, which is the condition in which an amide bond is least likely to hydrolyse. Cake appearance varies between lots for reasons that have nothing to do with content, so the volume occupied in the glass is not a measurement. Nothing about the tesamorelin 10mg vial is sold by volume.
Doing the division
Milligram content is the unit the tesamorelin 10mg vial is sold in, because it is the only figure that makes two listings comparable. This listing has more than one strength, so the arithmetic has to be done per option: take the price of the option and divide it by its milligram content. The result is printed under each price. It is the number that makes two vial sizes, and two vendors, comparable at all. Compare the tesamorelin 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 tesamorelin 10mg vial
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 tesamorelin 10mg vial is specific to the lot and not to the product line.
Assays are run by an outside contract laboratory rather than in house. Independence of that kind matters, and it has a limit: the figure still depends on the sample that was submitted, which is why lot by lot testing rather than periodic testing is the part that matters. Stock is withdrawn from sale where the certificate for the tesamorelin 10mg 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
Two weights can be quoted for a vial. One is everything the balance sees, which includes salt from the purification step and whatever water stayed in the cake. The other is the peptide alone. Only the second is a sound basis for comparison, and a vendor who does not say which one is being quoted is leaving the more flattering reading available. The same methods are run on the tesamorelin 10mg 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.
Names, abbreviations and how to keep the tesamorelin 10mg vial
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. GHRH is left abbreviated. The long form of the abbreviation describes an action, and that is not a description this page offers. The catalogue name carried by this 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 vial, since the lot number is the only thing joining the two.
Research use only: this vial is a reagent
Sold to qualified purchasers for laboratory research only. Not for human or veterinary use. The page carries no dosing information, no protocol, no administration instructions and no account of physiological activity, because publishing any of those would be describing a use this material is not sold for. We will not supply them privately either. 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, and the FDA warning letter archive.
Lots that failed their own stated figures are kept rather than deleted, which is the point of an archive as against a highlight reel. This item sits on the metabolic peptide shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
