On February 25, 2013, the FDA issued a warning letter to Altasource, LLC, dba Meta Labs LLC, following a facility inspection which found the company's dietary supplements, including Respiratory Response, African Mango, Coffee Black Salve, Meta-Cell, Conjugated Linoleic Acid and Red Yeast Rice with CoQ-10, to be adulterated because they were were prepared, packed, or held under conditions that do not meet the Current Good Manufacturing Practices regulations for dietary supplements.

These violations include failure to make and keep written procedures for the responsibilities of the quality control operations, failure to establish laboratory control processes that are reviewed and approved by quality control personnel, and failure to prepare and follow a written master manufacturing record for each unique dietary supplement formulation.

In addition, statements made on Meta Labs' website about Respiratory Response, African Mango, Coffee Black Salve, and Meta-Cell were found to be drug claims.

Respiratory Response contains tylophora, Ophiopogon japonicas, astragalus, Codonopsis pilosula, cordyceps, bupleurum, Angelica sinensis, Chinese licorice root, long pepper, ginger, and prince ginseng. It was promoted for smoker's cough, asthma and emphysema with statements such as "Traditionally used to treat airway constriction due to asthma and other respiratory conditions."
