Androstenediol and Methyltestosterone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

TESTOSTERONE

Why this applies to Methyltestosterone

Methyltestosterone falls under TESTOSTERONE — the group Androstenediol interacts with.

Androstenediol is a precursor to testosterone and can increase levels of testosterone. There is some concern that taking androstenediol with testosterone might increase therapeutic and adverse effects of testosterone. However, androstenediol is converted to testosterone in low testosterone environments. Patients taking supplemental testosterone do not have low testosterone levels. Therefore, androstenediol might not be converted to testosterone in these patients. It is unclear how this might alter the effects and side effects of androstenediol. Until more is known, use with caution or avoid using with testosterone-containing drugs. Some of these drugs include Androderm Transdermal, AndroGel, Depo-Testosterone, Testex, Testoderm, and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Methyltestosterone is already a form of testosterone, so you're putting androgen hormone directly into your body. Androstenediol is a prohormone, meaning your body can turn it into more testosterone. Stack the two and you may be piling more androgen on top of androgen, which can push up the usual testosterone-type side effects: acne, oily skin, mood swings, fluid retention, and over time changes like shrinking testicles or, in women, deepening voice and unwanted hair growth.

Honestly, though, this concern is mostly theoretical. Androstenediol tends to convert to testosterone when your levels are low, and someone already taking methyltestosterone usually isn't low. So we can't say for sure how it behaves here. Methyltestosterone also strains the liver, so adding any extra hormone product is worth a careful chat. Please run this combination by your doctor or pharmacist first.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

From our pharmacist’s overview on the Methyltestosterone page

“Liver strain dominates this list, and it warrants real wariness before pairing supplements with methyltestosterone (Android, Testred, Methitest). This oral hormone is already hard on the liver by itself, and 38 of the 73 supplement ingredients on file carry their own liver toxicity, stacking injury on the same organ.”

About Androstenediol

What is Androstenediol?

Androstenediol
  • Boosting testosterone
  • Building muscle and strength
  • Enhancing athletic performance
  • Anti-aging / general vitality
  • Bodybuilding cutting or bulking cycles

Androstenediol is a prohormone (a precursor the body can convert into testosterone and other hormones) marketed to raise testosterone and build muscle, but solid human evidence for these benefits is lacking and it carries real hormonal risks. In the United States it is a Schedule III controlled substance and is banned in most competitive sports. Talk with a doctor or pharmacist before considering any product containing it.
