The present invention relates to improvements in compositions containing peptides that are ligands of the GHS receptor, or pharmaceutically acceptable salts thereof, methods for preparing such compositions, and methods of using such compositions to treat mammals. In particular, the present invention relates to a pharmaceutical composition comprising a pamoate salt of H-Inp-D-Bal-D-Trp-Phe-Apc-NH2, which is a ligand of the GHS receptor and in which, after subcutaneous or intramuscular administration to a subject, the peptide forms an in situ depot at physiological pH that is slowly dissolved and released into the body fluid and bloodstream. The present invention may further comprise an organic component such as dimethylacetamide (DMA) or polyethylene glycol with an average molecular weight of lower than 1000.
