Androsterone + Testosterone
Testosterone brand names: Intrinsa, Testim, Androgel, Andropatch, Testogel, and others.
Androsterone has a minor interaction with Testosterone. Androsterone, as an androgenic hormone, may interact with other androgenic drugs, such as testosterone, due to their similar mechanisms of action.
Read the full interaction reportAndrosterone and Testosterone
Here is the interaction we found between these two, with the evidence behind it.
Androgens
Why this applies to Testosterone
Testosterone falls under Androgens — the group Androsterone interacts with.
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.
Here's the simple version: androsterone is itself a weak male hormone, and so is the testosterone your doctor prescribed. Because they both switch on the same androgen receptors in your body, stacking them basically adds more hormone on top of more hormone. They don't block or speed up each other's breakdown, they just pile their effects together.
In real life that can mean a bit more of the usual testosterone-type side effects: oily skin or acne, scalp hair thinning, mood or libido shifts, and possibly throwing off the careful hormone balance your doctor is trying to dial in with lab checks. The good news is this is rated a minor, possible interaction with modest evidence. Still, androsterone is banned from legal supplements, so please loop in your pharmacist or doctor before adding anything like it.
What These Ratings Mean
Every interaction above is graded three ways — here’s the key to each label.

- ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- PossibleInteraction 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.
- UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
- AHigh-quality meta-analysis (quantitative systematic review).
- BCase-control study.

See Every Supplement That Interacts With Testosterone
This page covers Androsterone only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Testosterone page lists 170 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Beer (major), Grapefruit (major), Siberian Cocklebur (major), St. John's Wort (major) and Wine (major).
By severity: 5 major · 129 moderate · 36 minor.
From our pharmacist’s overview on the Testosterone page
“The supplement list for testosterone therapy (Androgel, Testim, Nebido, and others) deserves real attention, mainly because five of its 170 entries are rated major and four of those are everyday items: grapefruit, St. John's wort, and alcohol in the form of beer or wine.”

About Androsterone
What is Androsterone?
- Muscle building and athletic performance
- Boosting testosterone or androgen levels
- Supporting libido
- Bodybuilding 'prohormone' stacks
Androsterone is a natural androgenic steroid hormone made in the body, but supplement versions are classified as anabolic-androgenic steroids and are banned from U.S. dietary supplements under the DASCA law. There is no good evidence that taking it is safe or effective, and it carries the same hormone-related risks as other anabolic steroids. Avoid products that contain it, and talk to a pharmacist or doctor about safer, legal options.
About Testosterone
What Is Testosterone Used For?
Brand names: Intrinsa, Testim, Androgel, Andropatch, Testogel, Nebido, Delatestryl, Natesto, Vogelxo
Testosterone replacement therapy is used in adult males whose bodies do not produce enough of their own testosterone. This includes primary hypogonadism — where the testes themselves fail due to causes such as Klinefelter's syndrome, injury, chemotherapy, or surgical removal — and hypogonadotropic hypogonadism, where the brain's signaling system (the hypothalamus or pituitary gland) fails to trigger testosterone production.
Testopel (subcutaneous pellets) may also be used to stimulate puberty in carefully selected males with clearly delayed puberty. The safety and efficacy of testosterone for age-related (late-onset) hypogonadism have not been established for most products, including AndroGel, Testim, Jatenzo, Kyzatrex, Natesto, Depo-Testosterone, Testosterone Cypionate, and Xyosted.
