Since glutathione IV reduces melanin by decreasing tyrosine levels, wouldn't this also impact dopamine, adrenaline/nonadrenaline and thyroid glands in the body? And if so, this means that it may impact my memory, hormones, etc. right? If the answer is: that's why you take breaks after certain amount of sessions...along with dopamine, melanin would also return so to keep it you'd need consistent decrease in dopamine etc. levels which would impact the brain too?
