Durability Efficacy against symptomatic infection also waned over time for all vaccines (average decrease of 13.6% per month, 95% CI 5.522.3 [5]
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

Colostrum levels were 778 and 320 pmol/L (1,054 and 434 ng/L), respectively, and at 3 months postpartum were 235 and 170 pmol/L (318 and 230 ng/L), respectively.[25] Based on the 65 pmol/L (88 ng/L) difference in median milk levels reported at 3 months, exclusively breastfed infants would receive an extra 0.013 mcg/kg daily of vitamin B 12 from maternal 250 mcg once daily oral supplementation
