Chrysin and Diethylstilbestrol, Methyltestosterone

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

Minor

TESTOSTERONE

Why this applies to Diethylstilbestrol, Methyltestosterone

Diethylstilbestrol, Methyltestosterone falls under TESTOSTERONE — the group Chrysin interacts with.

Theoretically, chrysin might increase the effects and adverse effects of testosterone.
In vitro research suggests that chrysin and its sulfate conjugate inhibit testosterone metabolism. It is speculated that chrysin and its sulfate conjugate reduce the metabolism of testosterone by inhibiting cytochrome P450 3A4. This effect has not been reported in humans.
Severity Minor 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for the methyltestosterone part of your Tylosterone. In test-tube studies, chrysin appears to slow down the liver enzyme (CYP3A4) that helps break testosterone down. If that happened in your body, a bit more of the hormone could linger, which in theory might nudge up both its effects and its side effects. For methyltestosterone, that could look like more acne, oily skin, mood swings, fluid retention, or strain on the liver.

The big caveat: this is only seen in lab dishes, never confirmed in people, and the body absorbs very little chrysin to begin with. So I wouldn't lose sleep over it. Still, since you're on a hormone product, it's worth a quick chat with your pharmacist or doctor before adding chrysin.

From our pharmacist’s overview on the Diethylstilbestrol, Methyltestosterone page

“Tylosterone pairs diethylstilbestrol, an estrogen, with methyltestosterone, an oral androgen already known for stressing the liver, and that is exactly where this interaction list concentrates. I would handle these 73 supplements carefully.”

About Chrysin

What is Chrysin?

  • Bodybuilding and testosterone support
  • Anxiety and stress
  • Anti-inflammatory
  • Antioxidant support
  • Prostate health

Chrysin is a plant flavonoid sold mainly as a bodybuilding supplement claimed to raise testosterone or block estrogen, but human studies have not shown these benefits, largely because the body absorbs very little of it. Evidence for its other proposed uses is mostly limited to laboratory and animal research, so its real-world value is unclear. Talk with your pharmacist or doctor before using it.
