Description
Drostanolone propionate injection at 100 mg per mL in sesame oil with benzyl alcohol, supplied as a 10 mL multiple-dose vial holding 1,000 mg. The compound was a European product and has never held United States registration, and anabolic steroids are Schedule III here. Research use only, not for human consumption, adults 21 and over, with purchase restrictions by state.

Sesame oil and benzyl alcohol are both named because both matter. The oil is the only reason an ester this lipophilic is in solution at all, and the preservative is what makes a container that gets entered more than once defensible.
We shelve drostanolone propionate injection with the other the injectable solutions, under anabolic reference materials.
Position under United States law
There is no approved or marketed human drostanolone product in the United States and there never has been one. Anything described as a pharmaceutical equivalent is either a foreign registration or a compounded preparation, neither of which is an FDA-approved product. The compound is Schedule III as an anabolic steroid. See the DEA’s drug scheduling pages and the FDA’s drug information section.
Carrier, preservative and ester chemistry
Benzyl alcohol is an antimicrobial preservative, typically present at a low percentage, and it is the component that distinguishes a multiple-dose presentation from a single-use ampule. Sesame oil is a fixed vegetable oil with a long history as a parenteral vehicle. Neither is an active substance and both are part of the specification.
The propionate ester on the 17 beta hydroxyl takes drostanolone from about 304.5 to roughly 360.5, so 100 mg of ester per millilitre corresponds to near 84 mg of the parent steroid. Esterification drives solubility towards oil and slows hydrolysis of the bond, which is the only sense in which drostanolone propionate injection has a half life worth discussing on a specification page.
Milligrams per vial for drostanolone propionate injection
100 mg per millilitre across 10 millilitres is 1,000 mg. At $125 that is $0.125 per milligram of ester. The lab-grade vial at the same concentration sits at $0.094, and we print both figures rather than explaining away the difference.
Why price per milligram beats the price on the bottle sets out the arithmetic we apply to every listing on the site.
Specification and certificate
The specification is what drostanolone propionate injection is sold against, and the certificate is the evidence for it. Purity by HPLC, expressed as percent of total peak area. Identity by mass spectrometry against the expected molecular mass. Residual solvent in parts per million. Appearance and, where the dosage form calls for it, uniformity of content across units. The contract laboratory producing those figures is independent of this company and always has been, and the lot number on the container of drostanolone propionate injection is the index back to its report.
Our guide to reading a certificate of analysis works through one of these documents line by line, and the full set sits on the lab results page.
What this page does not contain
No dosing tables. No protocols. No comparisons of potency between compounds, and no description of what drostanolone propionate injection does in a living organism. Those are not omissions we will fill in on request, including in order notes and in messages to our staff.
The reasoning is on the public record. The pattern the FDA has pursued in writing is pages that pair a research-use-only line with human outcomes, protocols or quantities for drostanolone propionate injection, and the disclaimer does not rescue the page it sits on. Research use only is not a legal strategy goes through the letters, and the FDA’s drug information section carries the agency’s own material.
Traceability
Lot number first, everything else second. The number printed on the container is the key to the assay report, the receipt date, the method and the archive copy, and it is the only part of the label that cannot be reconstructed from the catalogue. Content per unit, container count and storage conditions for drostanolone propionate injection are also on the label and on the listing. If the two disagree, the label is the document that travelled with the material, so the label wins and we want to hear about it.
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.
US regulatory status. No drostanolone product is currently approved or marketed for human use in the United States.
