Yang et al., 2022
Typical Cycle Lengths Mild to moderate injury (tendon, ligament, muscle): 24 weeks at 250500mcg per day Severe or post-operative injuries: 46 weeks, sometimes extending to 8 weeks Gastrointestinal issues (ulcers, IBS): 46 weeks at 250500mcg per day, oral or subQ Neurological repair or systemic inflammation: 46 weeks, systemic dosing recommended For most users, results begin to show within the first 710 days , especially in soft tissue or gut repair cases
This appears as temporary breakouts as old skin cells turn over faster
The foundation of research backing GHK-Cus efficacy is strong, its mechanisms of action are sound, and the safety profile works in the peptides favor
A well-formulated peptide routine can help support skin that feels nourished while improving the appearance of texture and overall radiance
