Cycle structures for different goals General anti-aging and skin health: 4 weeks on, 4 weeks off Repeat cycles as needed Many users report retained benefits during off periods for skin-related effects Injury recovery: 6-8 weeks continuous, or until recovery milestone achieved May use intensive protocol initially, tapering to standard after 2 weeks Minimum 4-week break before starting new cycle Athletic recovery and performance: 4 weeks on, 2 weeks off Can continue rotating cycles during training blocks Take extended 4-6 week break every 3-4 cycles Chronic condition support: Longer cycles of 8-12 weeks may be appropriate under medical supervision Lower maintenance dosing during extended use Regular assessment of continued benefit versus potential tolerance What happens during rest periods Many of the structural benefits, collagen remodeling , tissue repair, improved skin texture, persist beyond active peptide use
