The present invention provides composition of comprising a therapeutically effective amount of at least one peptide, polypeptide, analog or derivative thereof and a sufficient amount of at least one stabilizing agent to improve the stability of the peptide, polypeptide, an analog or derivative thereof, wherein at least one stabilizing agent is a medium chain fatty acid salt, an ester, an ether, or a derivative of a medium chain fatty acid and has a carbon chain length of from about 4 to about 20 carbon atoms or is a surface active agent. The method for preparation of a composition of a peptide, polypeptide, protein, an analog and/or derivative thereof is also provided. The process comprises mixing the peptide, polypeptide, protein, an analog or derivative thereof with a sufficient amount of at least one stabilizing agents to improve the stability of the peptide, polypeptide, protein, an analog or derivative thereof, and the agent is a medium chain fatty acid salt, an ester, an ether, or a derivative of a medium chain fatty acid and has a carbon chain length of from about 4 to about 20 carbon atoms or is a surface active agent.
