Description
Boldenone undecylenate injection at 50 mg per mL in sesame oil with benzyl alcohol, supplied as a 50 mL multiple-dose vial holding 2,500 mg. The presentation carries veterinary labelling for equine use and there is no human registration in the United States. Anabolic steroids are Schedule III. Research use only, not for human or veterinary consumption, adults 21 and over, with purchase restrictions by state.

Low concentration, large volume. That combination is unusual on this shelf and it changes the arithmetic: the vial holds less per millilitre than most and more in total than any of them.
Catalogued in the injectable shelf, alongside the rest of the anabolics reference stock.
Regulatory position in the United States
No boldenone product is approved for human use in the United States. The approved form is veterinary and is indicated for horses, so the only lawful registered use of boldenone undecylenate injection in this country is in an animal under a veterinarian’s direction, and this vial is not supplied for that either. The compound is Schedule III as an anabolic steroid. See the DEA’s scheduling pages and the FDA’s drug information section.
Carrier oil, preservative and ester
Sesame oil is the vehicle and benzyl alcohol is the antimicrobial preservative that makes a multiple-dose container defensible. Neither is inert filler: the oil is what dissolves an ester this lipophilic, and the preservative is why a 50 mL vial can be entered more than once without the contents becoming an unknown.
The ester itself is an eleven carbon undecylenate chain on the 17 beta hydroxyl of boldenone. Esterification pushes solubility towards oil, slows hydrolysis of the bond, and adds mass: boldenone is about 286.4 against roughly 452.7 for the ester, so the parent accounts for about 63 percent of what the label counts. 50 mg of ester per millilitre is therefore near 32 mg of boldenone per millilitre.
Milligrams per vial for boldenone undecylenate injection
50 mg per millilitre across 50 millilitres is 2,500 mg. At $185 that is $0.074 per milligram of ester. The 300 mg per millilitre vial on the shelf above holds 3,000 mg for less money, and the per-milligram figure makes that visible immediately, which is the entire argument for printing it.
Why price per milligram beats the price on the bottle sets out the method we use for every listing.
Specification and certificate
The specification is what boldenone undecylenate 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 boldenone undecylenate 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 boldenone undecylenate 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 boldenone undecylenate 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 boldenone undecylenate injection are also on the label and on the listing. If the two disagree, the label is the document that travelled with boldenone undecylenate injection, so the label wins and we want to hear about it.
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.
US regulatory status. No boldenone product is approved for human use in the United States. The approved form is veterinary and is indicated for horses.
