This remains an actively moving area, however: on February 27, 2026, the HHS Secretary publicly announced an intent to move roughly 14 of the 19 Category 2-listed peptides, reportedly including ipamorelin and CJC-1295, back toward Category 1 status, and multiple industry and legal-news outlets reported further FDA action in the following months easing Category 2-related restrictions on this group of peptides

It should be noted that these studies measured total Cbl levels, but as previously mentioned, the biologically available form of Cbl, TCN2-Cbl, comprises only approximately 2030% of the total Cbl level, which may lead to a significant number of false negatives for clb deficiency
