We found no known interaction between Androsterone and Oxytetracycline , Polymyxin B in our sources.

Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Androsterone and Oxytetracycline , Polymyxin B
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 Oxytetracycline , Polymyxin B and Androsterone 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.
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 Oxytetracycline , Polymyxin B page
“St. John's wort is the entry I'd check first for anyone using Terak (oxytetracycline with polymyxin B), since both the herb and this antibiotic's tetracycline component can make skin react more strongly to sunlight.”

About Androsterone
What is Androsterone?
- Muscle building and athletic performance
- Boosting testosterone or androgen levels
- Supporting libido
- Bodybuilding 'prohormone' stacks
Androsterone is a natural androgenic steroid hormone made in the body, but supplement versions are classified as anabolic-androgenic steroids and are banned from U.S. dietary supplements under the DASCA law. There is no good evidence that taking it is safe or effective, and it carries the same hormone-related risks as other anabolic steroids. Avoid products that contain it, and talk to a pharmacist or doctor about safer, legal options.
Not applicable (a steroid hormone, not a plant) · Historically sold as oral capsules, tablets, and sublingual products in 'prohormone' supplements (now banned in the U.S.)
An interaction check asks whether these two react with each other — it does not ask whether Androsterone is a good idea for someone in your situation. Here is what our Androsterone record says about it on its own.
Androsterone: dosing
There is no established or recommended safe dose of androsterone as a supplement, and it is illegal to sell in U.S. dietary supplements. We do not provide dosing for it.If you see a product that lists androsterone or one of its alternate names on the label, treat it as a banned anabolic steroid rather than a normal supplement.
