We included 45 healthy participants (female 11, male 34, age 24.16 6.67 years [range 1853], BMI 23.22 2.09 kg/m 2 ) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative)

Before any of that, the careful groups check two unglamorous things about the research-grade GHK-Cu they start with: how pure it is, and exactly how much copper is bound to it

This collaborative approach supports better long-term outcomes (Comparative Efficacy of Chiropractic Adjustments in Peripheral Neuropathy Management, n.d.)
