Mhmm kinda better to cycle it tbh, even if it’s one of the safest peptides out there. Continuous use can lead to receptor desensitization over time, meaning your body just stops responding as well to it. Classic 3 months on / 1 month off keeps the receptors fresh and you’ll actually feel the difference when you restart imo
Not exactly at 3 months, injectable GHK-Cu starts showing real results around 4-6 weeks, with effects compounding through weeks 8-12 where you hit the peak. The 3 month on / 1 month off protocol makes sense not because benefits start at 3 months but because you want to ride the full peak window before cycling off to avoid receptor desensitization and let copper metabolism reset. At the end of the day GHK-Cu is pretty individual, some people run it 5 days on 2 off year round, others prefer cycles, just go with what works for you.
