The Long Shot: Mechanism of Action

Reported Mechanisms — Component by Component

Each section below summarizes the published mechanism of a single component. No combined mechanism is described in the literature, and none is asserted here.

1. NAD+ (2,000 mg across 2 vials) — Redox Coenzyme and Enzyme Substrate

NAD+ operates both as an electron carrier in redox reactions and as a consumed substrate for enzyme families including sirtuins, PARPs, and CD38.[1][4] Tarragó et al. reported that a specific CD38 inhibitor reversed tissue NAD+ decline in an ageing model, and Zhang et al. reported that NAD+ repletion affected mitochondrial and stem-cell function in mice.[5][6] Grant et al. published a pilot study characterizing the plasma and urine NAD+ metabolome during intravenous infusion.[7]

2. GHK-Cu (100 mg, 1 vial) — Copper Coordination and Matrix Signalling

GHK binds Cu(II) with high affinity; Pickart et al. proposed that the complex facilitates copper uptake into cells.[8] Reported activities in fibroblast and skin models include stimulation of collagen synthesis, modulation of MMP-2 expression, and effects on MMP/TIMP balance and matrix proteins.[11][13] Pickart and colleagues also reported broad gene-expression modulation and antioxidant-gene regulation.[9][10][14]

3. Thymosin Alpha-1 (20 mg across 2 vials) — Toll-Like Receptor and Dendritic-Cell Signalling

Romani et al. reported that Thymosin Alpha-1 activates dendritic cells for antifungal Th1 resistance through toll-like receptor signalling, and in a later study reported activation of dendritic-cell tryptophan catabolism establishing a regulatory environment balancing inflammation and tolerance.[16][18] Serafino et al. reported activation of complement-receptor-mediated phagocytosis in human monocyte-derived macrophages.[20] Li et al. reviewed its biological activities and production, and Elizondo-Riojas et al. published an NMR structure.[19][22]

No published pharmacokinetic, pharmacodynamic, or interaction study has evaluated NAD+, GHK-Cu, and Thymosin Alpha-1 administered together. Any combined behaviour is unstudied.
