ghk-cu copper redox activity silenced Does Really Work? 40 Years of Research Reviewed Expression and Purification of Recombinant

This is a commonly referenced study from 1963 claiming a half-life of 5-6 days: nature.com/articles/198200a0 Although I would not cite it as an authority, the six-day half-life has also made it onto the B12 page in Wikipedia, seemingly unchallenged

Summarizing, NaBPC157 proves useful as an antiarrhythmic, antianginal and cardioprotective agent

This is the best-supported use of GHK-Cu and the only one backed by solid human evidence

LDH activity was normalized based on the amount of total protein

Oral administration may be preferable for gastrointestinal issues, while injections may be more effective for muscle recovery and wound healing
