Anastrozole 1mg, 50 tabs

Description

Anastrozole 1mg per tablet, fifty tablets to the bottle, sold as a laboratory reference material. Anastrozole is a nonsteroidal triazole that acts as a competitive aromatase inhibitor, and in the United States it is an approved, marketed, generic prescription medicine that is not a controlled substance. Research use only, not for human consumption. Adults 21 and over, with purchase restrictions by state.

Specification

One milligram is a small amount of material to put in a tablet, so most of each unit is excipient. That is ordinary for this class and it is also why uniformity of content across units appears on the certificate rather than purity alone.

We shelve anastrozole 1mg with the other ancillaries, under anabolic reference materials.

Regulatory status in the United States

Unlike most of the parent shelf, anastrozole 1mg is approved, marketed and available from multiple generic manufacturers in the United States, and it is not scheduled under the Controlled Substances Act. That is a statement about regulatory status and nothing else. Approval records are published through the FDA’s drug approvals and databases, and the federal schedules themselves are at the DEA’s drug scheduling pages.

What the anastrozole 1mg molecule is

The full chemical name is 2,2′-[5-(1H-1,2,4-triazol-1-ylmethyl)-1,3-phenylene]bis(2-methylpropiononitrile), which is a benzene ring carrying two nitrile groups and a triazole arm. Molecular mass is about 293.4. There is no steroid skeleton anywhere in it, which is the structural difference between this class and the steroidal inactivators sold a few listings over.

The triazole nitrogen is what coordinates to the haem iron of the aromatase enzyme, and the binding is reversible and competitive. That is enzymology from the published literature, measured in isolated systems, and we are not extending it into a statement about anastrozole 1mg.

Fifty milligrams in total

Fifty tablets at 1 mg each is 50 mg of anastrozole in the bottle. At $54 that is $1.08 per milligram, which looks expensive next to a gram of something cheap and is simply what low-strength unit dosage forms cost: you are paying for fifty compression events and fifty uniformity checks, not for bulk material.

Our note on price per milligram explains why we print the figure anyway, including the listings where it does not flatter us.

Reading the lot certificate

Start at the header, not the numbers. The laboratory name, the method reference, the date the sample was received and the lot it came from are what make the rest of the page mean anything. Then the HPLC purity figure for anastrozole 1mg, as a percentage of total peak area. Then the mass spectrometry identity confirmation, which is the measured mass set against the expected molecular mass. Then residual solvents in parts per million. The laboratory issuing it has no ownership connection to this company, which is the part that cannot be reconstructed from the figures themselves.

Check the lab before you check the numbers explains why we put the header first, and how to read a certificate of analysis covers the fields in order.

Specifications only

Everything above is a property of anastrozole 1mg or of its paperwork. There is no section on use, because there is no version of a use section for this family that we are willing to write, and requests for one are declined rather than quietly ignored.

What we will answer about anastrozole 1mg: what the assay returned, what the lot number refers to, what the carrier and preservative are, whether we can ship to a given state. Why research use only is not a legal strategy covers the regulatory background, and the FDA’s drug information pages carry the agency’s own statements.

Packaging notes

We ship anastrozole 1mg in the original sealed container with the lot number legible. We do not decant, relabel or combine lots, because a reference material whose lot cannot be named is no longer a reference material. The listing for this item states the storage conditions and the stability window we are willing to stand behind. Nothing is supplied in unmarked packaging, and we will not omit the compound name from a label or a customs declaration.

Research use only. Not for human consumption. Adults 21 and over, purchase restrictions by state, both stated on the listing for this item and enforced at checkout. Not a drug, not a dietary supplement, not a food. The lot certificate for this item and the full archive, failures included, are published on the lab results page.
