Description
Testosterone propionate 100mg per millilitre in oil, 10 mL vial, 1,000 mg of ester in the container. No testosterone propionate product is currently marketed in the United States, although other testosterone esters are, and the compound is Schedule III. Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state.

The propionate is the shortest ester in this catalogue, so the parent steroid makes up more of the labelled mass than in any other testosterone listing here: about 84 percent for testosterone propionate 100mg.
We file testosterone propionate 100mg under oil solution reference materials. The parent shelf is anabolics.
Testosterone propionate 100mg: the shortest chain on the shelf
Propionic acid is three carbons. Esterified at the 17 beta hydroxyl it takes testosterone from about 288.4 to roughly 344.5, which is a smaller addition than any other ester we stock. 100 mg of ester per millilitre is therefore near 84 mg of testosterone per millilitre.
Short esters are less lipophilic and hydrolyse faster than long ones. Both of those are properties of the ester bond measured in the laboratory, and they explain why a short ester sits comfortably at 100 mg per millilitre while the long esters are formulated at 200 or 250. We stop the discussion at the chemistry.
One thousand milligrams of ester
100 mg per millilitre times 10 millilitres is 1,000 mg of ester, around 837 mg of testosterone. At $59 that is $0.059 per milligram of ester or about $0.070 per milligram of parent steroid, and the gap between those two figures is the smallest on the injectable shelf.
Our note on price per milligram explains why the ester correction matters when comparing testosterone propionate 100mg against a decanoate or an undecanoate.
United States regulatory status
No testosterone propionate product is currently marketed in the United States, although other esters of testosterone hold current approvals and are on sale. So the molecule is familiar, the class is approved, and this particular ester has no marketed product: three separate facts. Testosterone propionate 100mg is Schedule III. The FDA’s drug approvals and databases and the DEA hold the records.
The assay, and the lots that fail it
Every lot of testosterone propionate 100mg is assayed before it is listed. HPLC returns purity as a percentage of total peak area, mass spectrometry confirms identity against the expected mass, and residual solvents are reported in parts per million. A lot assaying below its stated milligram content is withdrawn from sale, and its certificate stays on the results page with the rest of them, because a results page carrying nothing but passes tells you nothing about the ones that did not pass. The figure published is the figure the assay returned, not a rounded version of it.
Why we publish the batch that failed is the longer version of that argument, and our certificate guide covers the fields.
Container, label and lot
The label on testosterone propionate 100mg 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.
Declined on request
No quantities, no protocols, no sequencing, no potency rankings, no physiological description of testosterone propionate 100mg. If you ask us by email, the answer is the same as the answer on the page, which is that we do not supply it.
Keeping this listing to specifications is what makes the specifications worth anything. Research use only is not a legal strategy, and the FDA has said so in writing explains how the agency reads pages that go further, and the FDA’s drug information section holds the source documents.
We sell this item as a laboratory reference material, for research use only and not for human consumption. Adults 21 and over, with purchase restrictions by state: the product page lists the exclusions and the cart applies them. This is not a drug, a dietary supplement or a food, and it is not approved for administration to a person or an animal. Every lot certificate is published on the lab results page.
US regulatory status. No testosterone propionate product is currently marketed in the United States, although other testosterone esters are.
