Androgens
Desoxymethyltestosterone
An active designer androgen with animal toxicity signals and direct evidence that a product label may misidentify its contents.
Preclinical receptor/organ study plus primary commercial-product analysis; evidence checked 2026-10-01
Also known as: Madol
Practical use
Evidence interpretation and concrete review questions
- Clarify the abbreviation
- Use the full steroid name in health records.
- Preserve the package
- Keep the lot and ingredient list when reviewing an adverse effect.
- Read all tissues
- Do not select only the muscle or prostate result from an animal experiment.
Overview
Desoxymethyltestosterone is also called Madol; the abbreviation DMT here refers to this steroid. Receptor and animal experiments show direct androgenic activity, so it should not be assumed to require conversion into testosterone before acting.
Risks and limitations
Rat experiments found increased heart weight and altered liver signaling. Those are preclinical warning signals, not human event rates. A separate product investigation adds uncertainty about what an exposed person actually received.
How to read this
A molecule’s pharmacology and a seller’s product identity must both be established before interpreting a claimed effect.
Research explained
Madol pharmacological profile
Who was studied
Receptor assays and experiments in castrated male rats.
What was found
The steroid activated the androgen receptor and increased a muscle-weight endpoint; heart weight also increased. Prostate and seminal-vesicle weights were not stimulated under the tested conditions.
What it cannot establish
Tissue selectivity in this model does not establish human cardiovascular safety or a favorable clinical risk ratio.

Who was studied
Chemical analysis of one internet-purchased product labeled as desoxymethyltestosterone.
What was found
Mass spectrometry and NMR identified a different steroid, 17,17-dimethyl-18-nor-5α-androst-13-en-3β-ol.
What it cannot establish
One product cannot establish the prevalence of mislabeling, but its label was not reliable identity evidence.
Read the original studySelectivity is outcome-dependent
A lack of prostate-weight change does not cancel an increase in heart weight.

A package name is useful in an exposure history but does not authenticate the contents.

Incorrect
A SARM-like animal profile proves organ safety.
The same study reported organ-related warning signals.

Can every Pheraplex result be assigned to this molecule?
No. A directly analyzed product contained a different steroid.
