Testosterone Enanthate 250mg/ml

Description

Testosterone enanthate 250mg per millilitre in oil, 10 mL vial, 2,500 mg of ester in the container. The enanthate is the straight-chain seven carbon ester, and testosterone esters are Schedule III controlled substances in the United States. Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state.

What is in the ampule

At 400.6 against 412.6, the enanthate and the cypionate are close in mass, so their parent fractions are close too. Everything else about the two esters, including solubility in the carrier, differs a little.

Catalogued in the injectable shelf, alongside the rest of the anabolics reference stock.

Two thousand five hundred milligrams of ester

250 mg per millilitre across 10 millilitres is 2,500 mg of ester, near 1,800 mg of testosterone. At $55.20 that is about $0.022 per milligram of ester and $0.031 per milligram of parent steroid, which makes this one of the lowest per-milligram listings in the catalogue.

Price per milligram beats the price on the bottle and why we publish the batch that failed explain what the figure does and does not tell you.

Testosterone enanthate 250mg: seven carbons on the 17 beta hydroxyl

Enanthic acid, also called heptanoic acid, esterified at the 17 beta position. Testosterone is about 288.4 and the ester roughly 400.6, so the parent steroid is near 72 percent of the labelled mass and 250 mg of ester corresponds to about 180 mg of testosterone.

A straight seven carbon chain is more lipophilic than a three carbon propionate and less so than a ten carbon decanoate, and the ester bond hydrolyses at a rate that follows the same ordering. Those are properties of the chemistry of testosterone enanthate 250mg, which is as far as a specification page can usefully go.

United States regulatory status

Testosterone enanthate holds current United States approval in pharmaceutical presentations and is a Schedule III controlled substance as an anabolic steroid. Both are true simultaneously, and neither makes testosterone enanthate 250mg a medicine: it is reference stock. The FDA’s drug approvals and databases and the DEA hold the approval record and the schedules.

Container, label and lot

The label on testosterone enanthate 250mg carries the compound name, the content per unit, the container count or fill volume, the lot number and the date the lot was assayed. Those five things are what make a reference material traceable, and a container missing any of them is a container of unknown provenance whatever is written on the invoice. Storage conditions for this item are printed on the listing. Sealed containers are shipped sealed, and we do not repackage into unlabelled vials or bottles on request.

Testing on this lot

Purity for testosterone enanthate 250mg is measured by HPLC and published as the percentage of total peak area the expected compound accounts for. Identity is confirmed by mass spectrometry, which is a different claim: it says this molecule has the mass the structure predicts, and a pure sample of the wrong molecule would fail there rather than on purity. Residual solvent is given in parts per million. System suitability and the reference standard used are named on the report, because a purity figure without a method behind it is a number somebody typed.

The same two tests run on every lot of testosterone enanthate 250mg that we list. How to read a certificate of analysis and check the lab before you check the numbers both apply to the document on this page.

Questions we decline

The question people actually want answered about testosterone enanthate 250mg is what it does and how much. We do not answer it, in copy or by email, and a research-use-only sentence at the bottom of a page that answered it would be decoration.

So the listing for testosterone enanthate 250mg stays with the things that are verifiable: content per unit, purity, identity, solvent residue, lot number, where the item can ship. Our article on research use only explains why that line is a description of a sales channel rather than a legal shield, and the FDA’s drug pages hold the agency’s position in its own words.

Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state. Where a state excludes this compound the listing says so before checkout rather than after it. Nothing on this page is offered as a drug, a supplement or a food. The certificate for the lot you receive, and the certificates for the lots we withdrew, are on the lab results page.
