Aggressive protocol: 16-24 weeks for maximum results For significant aging or ambitious goals: Weeks 1-16: High-intensity phase Dose: 2-3mg per injection Frequency: 5-7x weekly (daily or near-daily) Total weekly: 10-21mg Topical: 2% serum twice daily (face/neck) Consider microneedling monthly Expected investment: 50mg vial lasts 2-5 weeks Need 3-8 vials for 16-week protocol Cost: $480-1,200 total More intensive but faster results Aggressive protocol timeline: Who should try aggressive: Age 50+ with significant aging Special events (wedding, reunion in 4-6 months) Have tried standard protocol with good results Want maximum possible improvement Can afford higher cost Who should avoid aggressive: First-time peptide users (start standard) Younger users (20s-30s, less to improve) Budget-conscious Impatient types (still takes 8+ weeks for visible results) Maintenance protocols after initial treatment Transitioning to maintenance: After achieving desired results (typically 12-24 weeks intensive) Goal shifts from improvement to preservation Reduce frequency and/or dose More sustainable long-term Maintenance dosing options: How long to maintain: Indefinite if want to keep results Stopping leads to gradual regression (see below) Most people choose lifelong maintenance Can cycle on/off but lose gains during off periods Periodic intensive bursts: Maintenance most of year Intensive protocol 8-12 weeks annually "Refresh" results Cost-effective long-term strategy See our peptide cycle planning guide and can you cycle different peptides
