The bottom line No known interaction

We found no known interaction between Stenabolic and Posaconazole 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.

Stenabolic and Posaconazole

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 Posaconazole and Stenabolic 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 Stenabolic at all — not against Posaconazole, 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.

What Posaconazole’s Own FDA Label Lists

This is not an interaction — none of it involves Stenabolic. These are the most notable effects listed in the ADVERSE REACTIONS section of Posaconazole’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • An electrolyte imbalance Worth acting on
  • Low magnesium Worth acting on
  • A low white blood cell count Worth acting on mentioned in 11.2% of FDA reports for Posaconazole
  • Low potassium Worth acting on
  • Blood clots Worth acting on
  • High blood sugar Worth acting on
  • An irregular heartbeat Worth acting on
  • A low platelet count Worth acting on mentioned in 3.3% of FDA reports for Posaconazole
  • Anemia Worth acting on
  • Raised blood pressure Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Posaconazole. Read the label on DailyMed › Where a percentage is shown, it is the share of 15,719 voluntary FDA FAERS reports for Posaconazole that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Stenabolic’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Stenabolic side to compare — that is a limit of the record, not a statement that Stenabolic has no side effects.

About Stenabolic

What is Stenabolic?

  • Endurance and stamina
  • Fat loss
  • Bodybuilding and athletic performance
  • Boosting metabolism

Stenabolic (also called SR9009) is an experimental research chemical, not a true dietary supplement, herb, or approved drug. It is sold online for fat loss and endurance, but it has never been tested for safety or effectiveness in humans, and it is banned in sports. Because the risks are unknown and product quality is unreliable, we do not recommend using it.

Synthetic compound (not from a plant) · Capsules, liquid solutions, powders

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

Stenabolic: dosing

There is no established or approved dose for Stenabolic because it has never been tested in proper human studies. Doses suggested on websites and forums are not based on safety research.We cannot recommend a dose. Given the lack of safety data, the risk of contaminated products, and its banned status in sports, the safest choice is not to use it at all.

About Posaconazole

What Is Posaconazole Used For?

Brand name: Noxafil

Posaconazole is used to treat invasive aspergillosis (a serious mold infection that can spread through the body) in adults and certain pediatric patients, depending on the formulation and weight. It is also used to treat oropharyngeal candidiasis (OPC) — a yeast infection of the mouth and throat, including cases that have not responded to itraconazole and/or fluconazole — and this use is specific to the oral suspension in patients aged 13 and older.

Posaconazole is also used for prophylaxis (prevention) of invasive Aspergillus and Candida infections in people at high risk because their immune systems are severely compromised — such as stem cell transplant recipients with graft-versus-host disease (GVHD) or people with blood cancers who have low white blood cell counts from chemotherapy. The specific formulation approved for prevention varies by age and weight.
