Analogs of CRF are disclosed that can be administered to achieve a substantial elevation of ACTH, beta -endorphin, beta -lipotropin, other products of the pro-opiomelanocortin gene and corticosterone levels and/or a lowering of blood pressure over an extended period of time. One analog which has been found to be particularly preferred is: [His20, Nle21, Leu38]-rCRF. In the analogs, one or more of the first five N-terminals residues may be deleted or may be substituted by a peptide up to 10 amino acids long and/or by an acylating agent containing up to 7 carbon atoms. A number of other substitutions may also be made throughout the chain. These analogs or pharmaceutically or veterinarily acceptable salts thereof, dispersed in a pharmaceutically or veterinarily acceptable liquid or solid carrier, can be administered to mammels, including humans. These analogs may also be used as stimulants to elevate mood and improve memory and learning.
