Description
Boldenone undecylenate in oil solution at 300 mg per millilitre, supplied in a 10 mL vial, which is 3,000 mg of ester in the container. This is one of the higher concentrations we carry. No boldenone product is approved for human use in the United States, the approved form is veterinary and indicated for horses, and anabolic steroids are Schedule III controlled substances. Research use only, not for human consumption, adults 21 and over.

Concentration and volume are separate facts and you need both. A 300 mg per millilitre label on a 5 mL vial and the same label on a 10 mL vial are two different quantities of boldenone undecylenate at two different prices.
We file boldenone undecylenate under oil solution reference materials. The parent shelf is anabolics.
Boldenone undecylenate as a molecule
Boldenone is testosterone with an extra double bond between carbons 1 and 2, which is why the older literature calls it 1-dehydrotestosterone. Molecular mass is about 286.4. The undecylenate ester is an eleven carbon chain with a terminal double bond, attached at the 17 beta hydroxyl, and the resulting ester has a mass of roughly 452.7.
That esterification is a chemistry change with two measurable consequences. Solubility shifts hard towards oil and away from water, which is why the material is presented in a carrier oil at all. And the parent steroid is now only about 63 percent of the mass, so 300 mg of ester corresponds to roughly 190 mg of boldenone. Hydrolysis of that bond is slow, which is the chemical sense in which long esters have long half lives.
Three thousand milligrams, and what that costs
300 mg per millilitre times 10 millilitres is 3,000 mg. At $71.20 the listing works out at about $0.024 per milligram of ester, or roughly $0.038 per milligram of boldenone once the undecylenate mass is taken out. Both figures are honest; they answer different questions, and the certificate reports the ester because the ester is what is in the vial.
Price per milligram beats the price on the bottle explains the comparison, and the certificate guide explains the assay.
United States regulatory status
There is no human registration for boldenone undecylenate in the United States and there never has been. The only approved form is a veterinary product indicated for horses, which is a genuine approval and not a near miss for a human one, and it does not make the material a medicine for anyone else. As an anabolic steroid it sits in Schedule III of the Controlled Substances Act. The DEA publishes the schedules and the FDA holds the approval records.
The assay, and the lots that fail it
Every lot of boldenone undecylenate 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 boldenone undecylenate 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 boldenone undecylenate. 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 boldenone undecylenate 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 boldenone product is approved for human use in the United States. The approved form is veterinary and is indicated for horses.
