Wu and Ng reported in 1993 that a synthetic fragment corresponding to residues 177 to 191 of hGH reproduced the antilipogenic activity of the whole molecule in isolated rat adipose tissue, which framed the C-terminal region as a candidate research tool

Critics counter that moving the compounds into legitimate pharmacies could create the appearance that they have been proved safe and effective when, in many cases, data from robust clinical trials remains limited
