Peps
ARA-290
ARA-290, also called cibinetide, is an erythropoietin-derived peptide investigated in tissue-protection research. A small clinical pilot examined neuropathy symptoms in people with sarcoidosis.

Host defense, immune signaling, and inflammation.
This topic groups related research questions. Shared biology does not make different peptides interchangeable, or establish a clinical benefit. Compare each paper’s population, preparation, and measured outcome.
Cortistatin
Cortistatin is a neuropeptide family investigated in inflammatory signaling. The selected study used a mouse arthritis model rather than people with rheumatoid arthritis.

Peptide bioregulators (Khavinson peptides)
Peptide bioregulators are very short synthetic peptides, two to four amino acids long, developed by Vladimir Khavinson and colleagues in St. Petersburg. Each is named for the tissue it was proposed to support. Almost all published research on them comes from that group and its collaborators.

Thymalin
Thymalin is a thymus-derived extract or peptide mixture. An older clinical report described long-term outcomes in elderly participants, but the abstract does not establish the methods needed for a firm causal longevity claim.

Thymosin alpha-1
Thymosin alpha-1, also called thymalfasin, is investigated for immune-related effects. The clinical value of immune modulation depends on the disease and endpoint.

Thymulin
Thymulin is a thymic peptide whose biological activity depends on zinc. The featured human study examined zinc status and thymulin activity; it was not a trial of thymulin injections.
