The most commonly reported side effects are mild and transient: injection site redness or minor bruising, transient fatigue in the first one to two weeks, and occasionally mild headache following the first few injections, a pattern sometimes attributed to the acute shift in cellular energy metabolism as AMPK pathways are upregulated [3]

Citrus fruits are rich in flavonoids for immunoregulation and potential targeting ACE2
Anabolic agent metabolites or isomers are also listed because they may be used as masking agents for the athlete biological passport (i.e

Moreover, it is worth noting that, despite the relatively high resolution of ERA5 compared to other global reanalyses, its spatial scale is still insufficient to explicitly resolve convection, which must therefore be parameterized
