Thymosin Alpha-1 (Tα1)
Studied in immune signaling research
The most clinically researched peptide on this menu — used to support immune function, vaccine response, and recovery from chronic immune challenges. Approved as a prescription drug (Zadaxin) in many countries.
Overview
Thymosin alpha-1 is a 28-amino-acid peptide originally isolated from thymic tissue. It has the deepest clinical research base of any peptide on this menu — over 11,000 human subjects across more than 30 trials — in immune-related contexts including chronic viral hepatitis, vaccine response, and sepsis. It is approved as the prescription drug thymalfasin (Zadaxin) in many countries outside the United States.
Evidence: established human research

Peptide therapy at Jaed Aesthetics is offered as a private wellness consultation service. None of the peptides discussed on this menu are FDA-approved for the wellness areas described, and some are investigational or available only through compounding pharmacies operating under FDA Sections 503A or 503B. Several peptides on this menu have primarily pre-clinical or animal evidence and limited published human data; we note this honestly under each entry. Any decision to proceed, the specific peptide selected, route of administration, dosing, monitoring, and pricing are determined one-on-one with our nurse practitioner during consultation. Nothing on this page constitutes medical advice, a diagnosis, or a treatment recommendation.
