Who manufactures testosterone cypionate?

Which companies make testosterone cypionate (brand and generic)?

Testosterone cypionate is widely manufactured as a generic androgen by multiple pharmaceutical companies. In the U.S., the product is also sold under brand names by specific manufacturers depending on the market and the product listing.

How do you find the exact manufacturer for the bottle you have?

The manufacturer can differ by product label and strength. Check the package/box for:
- The specific brand or generic name (e.g., “testosterone cypionate injection” plus strength)
- The “Manufactured for” / “Distributed by” line on the carton or vial label

Are there different manufacturers for different strengths or forms?

Yes. The same drug name can have different labeled manufacturers across:
- Concentrations (for example, 100 mg/mL vs other strengths)
- Package sizes
- Generic vs brand product listings

Can you tell me the manufacturer if you share the label?

If you paste the exact text from the “manufactured for” or “distributed by” section (or share the label name/strength), I can help identify the manufacturer tied to that specific product.
