Based on what’s publicly available, I would be cautious.
A lot number on the bottom of a supplement bottle is normal—it helps identify the manufacturing batch. However, a lot number alone is not evidence of third-party testing.
For Freerange Supplements & Nutrition’s ParaPurge:
- I could not find evidence that the product is certified by widely recognized independent testing programs such as NSF, USP, Informed Choice, or Informed Sport.
- Some pages that sell or promote ParaPurge claim it undergoes third-party testing, but they do not provide certificates of analysis (COAs), identify the testing laboratory, or link to verifiable reports.
- There are also numerous customer complaints online regarding billing, subscriptions, and customer service. While these don’t speak to product quality directly, they’re worth considering when evaluating the company.
If a company truly performs third-party testing, it’s reasonable to expect they can provide:
- A Certificate of Analysis (COA) for your specific lot number.
- The name of the independent testing laboratory.
- Information about what was tested (identity, potency, heavy metals, microbes, etc.).
If they can’t provide that when asked, it’s difficult to independently verify their quality claims.
If you already have the bottle, I can also help interpret the label. Feel free to upload a photo of the front, the Supplement Facts panel, and the bottom with the lot number.
