ARA-290 vs Thymosin α-1
An educational, source-based comparison of ARA-290 and Thymosin α-1 — how each peptide works, what it's researched for, and what to know before going deeper.
Erythropoietin-derived peptide researched for neuropathy and tissue repair.
A synthetic 11-amino-acid peptide derived from the erythropoietin molecule. Research indicates it retains the tissue-protective (non-erythropoietic) effects of EPO via the β-common receptor, without stimulating red blood cell production.
- Small-fiber neuropathy and sarcoidosis
- Diabetic neuropathy
- Ischemia-reperfusion injury
- Autoimmune modulation
- • Investigational; not FDA-approved.
- • Does not raise hematocrit like full EPO molecule.
A 28-amino-acid peptide naturally produced by the thymus. Research indicates it modulates T-cell maturation, dendritic cell function, and innate immune signaling. Approved in several countries (under the name Zadaxin) as an adjunct in hepatitis B/C and certain cancer protocols.
- Chronic viral hepatitis (approved use abroad)
- Vaccine response augmentation
- Immunosenescence
- Adjunct in oncology research
- • Approved in 35+ countries but not FDA-approved in the US.
- • Generally well tolerated in published clinical data.
- • Requires physician oversight.
ARA-290 vs Thymosin α-1 — Key differences
- Class: ARA-290 is classified as Neuropathic · Immune Modulation, while Thymosin α-1 is Immune Modulation.
- Primary research focus: ARA-290 — small-fiber neuropathy and sarcoidosis; Thymosin α-1 — chronic viral hepatitis (approved use abroad).
