Testolone and Acetaminophen, Pseudoephedrine, Triprolidine

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Acetaminophen, Pseudoephedrine, Triprolidine

Acetaminophen, Pseudoephedrine, Triprolidine falls under HEPATOTOXIC DRUGS — the group Testolone interacts with.

Theoretically, concomitant use might have additive hepatotoxic effects.
In a case report, a 52-year-old male was diagnosed with liver injury thought to be related to the use of products containing testolone. Also, elevated liver enzymes were commonly reported in a dose escalation study of testolone.
Severity Moderate Likelihood Possible Evidence B

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 piece to pay attention to in your Actifed Plus ES: the acetaminophen (the pain and fever reducer in the combo). Acetaminophen is processed by your liver, and in larger or frequent doses it can stress liver tissue. Testolone (RAD-140) has also been tied to liver injury, including elevated liver enzymes in studies and at least one case report. Putting two things that lean on the liver together could, in theory, add up to more strain on that organ.

To be clear, this concern is mostly theoretical and based on limited evidence, not strong proof. Still, watch for warning signs like yellowing of the skin or eyes, dark urine, belly pain, or unusual tiredness. Honestly, Testolone isn't an approved or safe product to begin with, so please talk with your pharmacist or doctor before mixing these.

From our pharmacist’s overview on the Acetaminophen, Pseudoephedrine, Triprolidine page

“Actifed Plus ES combines acetaminophen, pseudoephedrine, and triprolidine, and the pseudoephedrine is why I would check this page carefully before adding any supplement. Stimulation dominates the list: 44 ingredients, from ephedra to the everyday caffeine in coffee, tea, and cocoa, can stack on the decongestant and push blood pressure…”

About Testolone

What is Testolone?

  • Muscle building
  • Athletic performance and bodybuilding
  • Strength gains
  • Body recomposition (fat loss with muscle gain)

Testolone (RAD-140) is a synthetic experimental drug called a selective androgen receptor modulator (SARM), not a dietary supplement or herb, and it is not approved or proven safe for human use. It is illegally sold for muscle building, has been linked to serious harms including liver injury, and is banned in sports — it should not be taken outside of supervised clinical research.
