ImmuneHuman Trials
Thymogen

Also: EW Dipeptide, Glu-Trp

Clinical Trials

A synthetic dipeptide (Glu-Trp) bioregulator derived from Thymalin, a thymus extract. One of Professor Khavinson's key immunomodulatory peptides, shown to stimulate T-lymphocyte development and normalize immune function. Has been used clinically in Russia for immune support.

Mechanism of ActionThymosin Alpha-1 modulates T-cell function, enhances dendritic cell maturation, and promotes Th1 immune responses. It increases IL-2, interferon-alpha, and interferon-gamma production while reducing inflammatory cytokines.Thymogen (alpha-glutamyl-tryptophan) stimulates cellular factors of immunogenesis, promotes proliferation and differentiation of T-lymphocyte precursors into mature immunocompetent cells. It normalizes the ratio of T-helpers to T-suppressors, increases cyclic adenosine monophosphate (cAMP) in T-lymphocyte precursors, and modulates immune cell maturation. Pharmacokinetic studies show rapid tissue uptake, particularly in liver, adrenals, kidney, lymph nodes, and thymus.

Research SummaryApproved internationally for chronic hepatitis B and C. Studies show improved outcomes when combined with chemotherapy for cancer. Research demonstrates benefits in sepsis, immunodeficiency, and vaccine response enhancement.Originally isolated from Thymalin via reversed-phase HPLC, then synthesized. Clinical studies in Russia show immunomodulatory effects including normalization of T-cell subsets. Animal studies demonstrate geroprotective activity - Thymogen administration in rats led to increased survival and 1.5-fold decrease in tumor development. Has been used clinically for over 20 years as an immunomodulator.

Frequently Asked Questions: Thymosin Alpha-1 vs Thymogen

What is the difference between Thymosin Alpha-1 and Thymogen?

Thymosin Alpha-1 is a immune peptide that a naturally occurring thymic peptide that enhances immune function. approved in over 35 countries for hepatitis b/c and as an immune adjuvant. Thymogen is a immune peptide that a synthetic dipeptide (glu-trp) bioregulator derived from thymalin, a thymus extract. one of professor khavinson's key immunomodulatory peptides, shown to stimulate t-lymphocyte development and normalize immune function. has been used clinically in russia for immune support. The main differences lie in their mechanisms of action and clinical applications.

Which is better, Thymosin Alpha-1 or Thymogen?

Neither is universally "better" - the choice depends on your specific goals. Thymosin Alpha-1 is typically used for immune purposes, while Thymogen is used for immune. Always consult with a healthcare provider to determine which may be appropriate for your situation.

Can Thymosin Alpha-1 and Thymogen be used together?

Some peptide protocols combine multiple compounds for synergistic effects. However, using Thymosin Alpha-1 and Thymogen together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
