If you absolutely must use sterile water, you should plan to use the entire vial very, very quickly

Epitalons appeal lies in its unusually broad mechanistic reach: it can activate telomerase and support telomere maintenance in human cells [12,13,14, 15], modulate gene expression epigenetically by influencing chromatin accessibility and promoter interactions [4], enhance tissue repair in disease contexts such as diabetic retinopathy by reducing oxidative stress and EMT while improving wound healing in retinal cells [16], bolster redox homeostasis by upregulating endogenous antioxidant defenses and lowering DNA-damage markers [1], rebalance immune tone via IL-2 upregulation [17] and shifts in CD4+/CD8+ profiles [18], and even reset circadian biology by tuning core clock genes and melatonin dynamics [19, 20]
