Beyond 12 weeks: continued improvement and plateau Months 3-6 (weeks 12-24): Continued gradual improvement Gains slowing (diminishing returns) Approaching maximum benefit Maintenance becomes focus Plateau timeline: Most people plateau around month 4-6 Maximum collagen density reached Further dosing maintains vs improves Some continue seeing minor gains to month 9-12 Long-term expectations (6-12 months): When to transition to maintenance: Achieved desired results No new improvements for 4+ weeks Comfortable with current appearance Want to reduce cost/frequency Maintenance dosing: Reduce from 3-5x weekly to 2-3x weekly Or reduce dose (2mg 1mg) Maintains results without continued improvement More sustainable long-term Factors affecting how quickly you see results Age and skin condition: Dose and frequency impact: Higher dose = faster results (to a point) Daily dosing faster than 2-3x weekly But diminishing returns above 3mg daily Consistency more important than dose Combination approaches: Injectable + topical: Fastest results GHK-Cu + retinol: Synergistic (separate timing) GHK-Cu + vitamin C: Enhanced collagen GHK-Cu + microneedling: Accelerated penetration Lifestyle factors: Sun protection: Critical (sun damages collagen faster than GHK-Cu builds it) Sleep: 7-9 hours optimizes cellular repair Hydration: 8-10 glasses water supports skin Diet: Protein intake supports collagen synthesis Stress: High cortisol impairs results See our peptides before and after results and can you use peptides and retinol together
