Every Batch. Tested. Published.
We send every Therexa product to independent, accredited laboratories in the United States for third-party testing. Then we publish the results — not summaries, not badges, the actual reports.
Heavy Metals (Every Batch)
Every batch is screened for arsenic, cadmium, lead, and mercury to ensure safety.
Microbial Contamination (Every Batch)
Every batch is tested for bacteria, yeast, mold, E. coli, Salmonella, and other pathogens.
Identity Verification (Annual)
Each product undergoes annual identity testing to confirm the ingredients match exactly what's on the label.
Why This Matters?
- The supplement industry is largely self-regulated. Many brands never test their products - or only test once and reuse that report for years.
- We test every batch for safety. We verify every product annually for identity. And we will show you the results.
- If a brand won't publish their lab reports, ask yourself what they're hiding.
