The bottom line No known interaction

We found no known interaction between S-23 and Imipramine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

S-23 and Imipramine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Imipramine and S-23 in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for S-23 at all — not against Imipramine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Imipramine page

“Imipramine (Tofranil) is an older tricyclic antidepressant, and the supplements on this page deserve real scrutiny before you add one. Most of the list acts on the liver enzymes that process the drug, so an ingredient can quietly raise or lower imipramine levels: grapefruit pushes them up, while St.”

About S-23

What is S-23?

  • Muscle building
  • Fat loss
  • Athletic performance enhancement
  • Body recomposition
  • Investigational male contraceptive (research only)

S-23 is an experimental, non-prescription synthetic drug called a selective androgen receptor modulator (SARM), not a dietary supplement, herb, or natural product. It has never been approved for human use, has not been proven safe in people, and is banned in sports; we do not recommend using it.

Not applicable; S-23 is a synthetic chemical compound · Liquid solutions, capsules, and powders sold as 'research chemicals'

An interaction check asks whether these two react with each other — it does not ask whether S-23 is a good idea for someone in your situation. Here is what our S-23 record says about it on its own.

S-23: dosing

There is no established or safe dose of S-23 for humans. It has never gone through the clinical testing that would set a safe and effective dose, so any amounts shared online are unverified and potentially dangerous.We do not provide dosing guidance for S-23 because doing so could imply it is safe to use, which it is not.

About Imipramine

What Is Imipramine Used For?

Brand names: Tofranil, Tofranil PM

Imipramine is used to relieve symptoms of depression. Both Imipramine Hydrochloride tablets and Imipramine Pamoate capsules are approved for this use. Endogenous depression — the kind that seems to arise from within rather than a clear outside cause — tends to respond especially well. It may take one to three weeks before you notice the full benefit.

Imipramine Hydrochloride tablets are also approved as a short-term, add-on treatment to help reduce nighttime bedwetting (nocturnal enuresis) in children aged 6 and older, after a doctor has ruled out physical causes.
