Winder laboratories dextroamphetamine?

I’m not finding a credible source for a pharma company named “Winder Laboratories” that makes dextroamphetamine. Could you share more context—where you saw this name, or your country? It’s possible you meant a different company (there are many manufacturers of dextroamphetamine and related products).

General info that might help:
- Dextroamphetamine is a prescription stimulant used for ADHD and narcolepsy. It’s a Schedule II controlled substance in the U.S., meaning it requires a valid prescription and careful medical supervision.
- Brand names like Dexedrine and Dextrostat are common, and many manufacturers produce generic dextroamphetamine sulfate or dextroamphetamine salts. Adderall contains mixed amphetamine salts and is produced by different manufacturers.
- To verify a product’s manufacturer, check the medication label for the exact name, the strength, and the NDC (National Drug Code) number. Your pharmacist can tell you who made the lot.
- Never obtain or use dextroamphetamine without a prescription and from unverified sources; counterfeit or unsafe products can be dangerous.

If you can share the exact product name, country, or the NDC you’re looking at, I can help identify the manufacturer or provide more specific guidance.
