Immune supportLongevity
RouteSubcutaneous injection
+ Add to plan

Mechanism

A thymic peptide doing exactly what the thymus does: training up your T-cells, waking up dendritic cells, putting natural killer cells to work. It leans your whole Th1/Th2 balance toward fighting off viruses and tumors instead of sitting there.

Key Benefit

Approved in 35+ countries for hepatitis B/C and as cancer immunotherapy adjunct. Used as immune booster in chronic infection and immunosenescence.

Evidence Base

Approved abroad, as Zadaxin, in more than 35 countries. Multiple human trials behind it too, covering hepatitis, cancer as an add-on therapy, and sepsis. The one country where it's not approved: the United States.

Route & Rationale

Subcutaneous injection. Peptide requires parenteral delivery for systemic immune modulation.

Interactions

Caution in autoimmune conditions. Immune stimulation may worsen flares. Otherwise well-tolerated.

Regulatory Status

Not FDA-approved here. Approved in more than 35 countries as Zadaxin. You can get it through a compounding pharmacy in the meantime.
