Chronic patients with preserved corticospinal substrate but limited plasticity could receive a local or targeted EV product combined with intensive rehabilitation
In one mouse study, researchers found that the peptide reduced the pain felt by the animals in their paws when placed on a mildly hot plate. The authors explained that this could be because GHK is similar in structure to cimetidine, a histamine H2 receptor antagonist sometimes given to reduce pain in certain digestive conditions.3 10 In rodents, doses as low as 0.5mg/kg were found to be effective in delivering these anti-pain effects.25 In a 70kg human, an equivalent dose would be around 5.6mg, though thats likely higher than necessary: pharmaceutical-grade GHK-Cu normally ranges from 0.5 mg to 2.5mg per injection

Men are also more likely to develop conditions associated with reduced glutathione or higher oxidative stress, including, More visceral fat than women, which drives insulin resistance 49 Higher rates of sleep apnea, another contributor to oxidative stress 50 Cardiovascular disease, which occurs about 710 years earlier in men than in women on average 51 As estrogen declines through perimenopause and menopause for womenand remains lower in men overalldifferences in glutathione activity likely reflect hormonal influence as much as sex-based biology, Tennant says
Pregnant women, breastfeeding mothers, and people with kidney, liver, or severe respiratory problems should avoid glutathione, as improper supplementation can stress metabolic pathways and increase health risks
This means the plunger requires slightly more force, which can make precise dose drawing harder
