Androsterone and Testosterone Enanthate

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

Minor

Androgens

Why this applies to Testosterone Enanthate

Testosterone Enanthate falls under Androgens — the group Androsterone interacts with.

Androsterone, as an androgenic hormone, may interact with other androgenic drugs, such as testosterone, due to their similar mechanisms of action. Both androsterone and testosterone bind to androgen receptors in various tissues throughout the body, leading to similar physiological effects related to the development and maintenance of male secondary sexual characteristics. When taken together, these compounds can potentially amplify these effects, leading to an increased risk of androgenic side effects, such as acne, hair loss, and changes in libido. Additionally, combining androsterone with testosterone or other androgenic drugs may also affect hormone levels and balance in the body, potentially leading to hormonal imbalances or disruptions in the endocrine system.
Severity Minor Likelihood Possible Evidence C

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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both androsterone and your testosterone injection push on the same androgen receptors in your body. Androsterone is a weak androgen, so stacking it on top of Testosterone Enanthate (Xyosted) just adds more of the same hormone signal. This isn't a case of one drug speeding up or slowing down the other in your liver, it's more of an additive effect on top of the testosterone you're already getting.

What that can look like in real life is more of the usual testosterone side effects: acne, oily skin, mood or libido changes, and possible shifts in your lab numbers. The good news is the evidence here is modest and the interaction is rated minor. Still, androsterone supplements are actually banned in the U.S. and offer no proven benefit. Please loop in your doctor or pharmacist before mixing anything with your testosterone.

What These Ratings Mean

Minor

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

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • 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.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Testosterone Enanthate page

“Beer and wine both carry major ratings on this list, because heavy alcohol use can compound the strain testosterone enanthate (Xyosted) already places on the liver. That liver theme runs through 38 of the 184 ingredients on file, Siberian cocklebur among them, and with six interactions rated major overall, this page deserves genuine ca…”

About Androsterone

What is Androsterone?

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 Injection

What Is Testosterone Injection Used For?

Brand name: Xyosted

Testosterone injection is primarily used in men whose bodies do not produce enough testosterone on their own — a condition called hypogonadism. This includes primary hypogonadism (a problem with the testicles themselves, such as from injury, infection, or surgery) and hypogonadotropic hypogonadism (caused by problems in the brain's hormone signaling from the hypothalamus or pituitary gland). It is also used to stimulate puberty in carefully selected adolescent males with clearly delayed puberty who have not responded to other support.

Testosterone Enanthate Injection is also approved for use in women with advanced, inoperable metastatic breast cancer (specifically skeletal metastases) who are one to five years past menopause, or in premenopausal women with hormone-responsive breast cancer who have had their ovaries removed. This use should be directed by an oncologist. Aveed (testosterone undecanoate) is specifically approved for male hypogonadism only.
