Here is the interaction we found between these two, with the evidence behind it.
TESTOSTERONE
Why this applies to Diethylstilbestrol, Methyltestosterone
Diethylstilbestrol, Methyltestosterone falls under TESTOSTERONE — the group 4-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 thing to keep in mind: Tylosterone contains methyltestosterone, which is itself an androgen (a male hormone). 4-Androsterone is a prohormone, meaning your body may convert it into testosterone and similar androgens. So stacking the two together essentially piles more androgen on top of the androgen you're already taking.
This is a theoretical concern based on how these compounds work, not on solid human studies, so I don't want to alarm you. But more androgen overall can add up to side effects like mood swings or irritability, acne or oily skin, fluid retention, unfavorable cholesterol changes, and added strain on the liver (methyltestosterone is already known to be hard on the liver). Please loop in your doctor or pharmacist before combining these.

About 4-androsterone
What is 4-androsterone?
- Muscle building
- Strength and athletic performance
- Boosting testosterone
- Bodybuilding cycles
4-Androsterone (sometimes called 4-DHEA) is a lab-made prohormone marketed to bodybuilders as a way to raise testosterone and build muscle, but human studies are very limited and it carries real risks like liver strain, hormone imbalance, and cholesterol changes. Its legal status is uncertain in many places, and it may cause a positive result on drug tests. We do not recommend it without close medical supervision, and it should be avoided in pregnancy and breastfeeding.
