Tier 3. Synthetic dipeptide identified in Khavinson-tradition Russian peptide bioregulator research; used clinically in Russia for immunostimulation in chronic infection and post-surgical recovery. Western primary-literature replication is limited.

§ B · Mechanism of action

Reported to enhance T-lymphocyte maturation and proliferation, with downstream effects on natural killer cell activity and cytokine balance. Specific receptor target not definitively identified; signalling claims rest primarily on lymphocyte function assays in cell culture and rodent immunodeficiency models.

§ C · Human clinical evidence

Tier 3. Russian clinical literature includes small RCT-design studies in immunocompromised populations. No Phase 2 or 3 Western trials.

§ F · Safety signal

In published Russian clinical use, well tolerated. No comprehensive safety database meeting Western regulatory standards.

§ H · Regulatory status

Regulatory status

FDA status:
Not FDA-approved
§ I · Notable gaps and controversies

Khavinson-tradition peptide bioregulator literature carries the same methodological caveats as the broader Russian-origin small-peptide field — the work has not been independently replicated under contemporary Western trial methodology.
