Cordyceps' primary active compound is cordycepin (3'-deoxyadenosine), which is structurally similar to adenosine — the molecule that forms the backbone of ATP (your cellular energy currency). Cordycepin increases cellular ATP production, improves oxygen delivery to muscles by upregulating erythropoietin (EPO) gene expression, and reduces lactate accumulation during exercise. It also modulates the immune system by activating NK cells and macrophages while reducing inflammatory cytokines. The CS-4 strain was developed after wild C. sinensis became unsustainably expensive and frequently adulterated.
