The European Peptide Society is a non-profit association established for the public benefit to promote in Europe and in neighbouring countries the advancement of education and scientific study of the chemistry, biochemistry, biology and pharmacology of peptides. The EPS publishes, in co-operation with John Wiley & Sons, the Journal of Peptide Science and the EPS Newsletter. The EPS also organizes the bi-annual European Peptide Symposium, sponsors local and specialised meetings and workshops, and supports and promotes young scientists with travel grants and dedicated seminars.

The American Peptide Society, APS, a nonprofit scientific and educational organization founded in 1990, provides a forum for advancing and promoting knowledge of the chemistry and biology of peptides. The approximately fifteen-hundred members of the Society come from North America and from more than forty-five other countries throughout the world. Establishment of the American Peptide Society was a result of the rapid worldwide growth that has occurred in peptide-related research, and of the increasing interaction of peptide scientists with virtually all fields of science.

The Japanese Peptide Society supports the plans of peptide forum, which is organized by society members, publishes Peptide News Letters, and provides the Akabori Memorial Award, the Japanese Peptide Society Award, the Young Investigator’s Award, and Travel Awards for attending international symposiums.

The Polish Chemical Society was founded of 118 Charter Members on 29 June 1919. The statute states that one of the goals of the society is "the encouragement of progress of chemical science and propagation thereof among the public, as well as representation of the professional interests of chemists, both researchers and those industrially employed".

The aim of the Polish Biochemical Society (PTBioch) is to promote and support all aspects of biochemical research in Poland. To achieve these aims PTBioch organizes conferences, scientific discussions, meetings, lectures and workshops, and publishes scientific magazines. It also evaluates the situation and needs of biochemistry in Poland and deals with state authorities responsible for scientific policy. PTBioch maintains contacts with related societies in Poland and abroad.
