What is in it: label and official sources

The brand’s site (neptunesfix.com) could not be read, so no label is on file. The findings below come from FDA, the New Jersey Department of Health and a CDC report on lab testing.

Only ingredients disclosed on the label or identified by an official source (FDA, another government agency or lab, an accredited lab or a court record) are listed, each with its source. Compound Laws does not guess at undisclosed contents.
