Research suggests about 20 per cent of elderly people are B12 deficient

Peptides that don't require cycling Can use continuously : No tolerance development Use as needed for injuries Can run months continuously for chronic issues No need for breaks Healing peptides generally : Use when needed, stop when healed "Cycling" based on need, not arbitrary timeline Weight loss peptides : Use until goal achieved Transition to maintenance dose Not traditional "cycling" Maintenance doses : Low-dose ongoing use No breaks needed Prevents issue recurrence Peptides where cycling optional Growth hormone peptides : Can run continuously : Many people do Can cycle : 12-16 weeks on, 4 weeks off No evidence required : Personal preference Cycling rationale : Potential tolerance prevention (debated) Cost savings during off periods Mental break from daily injections Continuous use rationale : Maintains consistent benefits Simpler to manage No "restart" period Recommendation : Try 16 weeks continuous first

That framing is exactly why every reputable source labels its vials for laboratory study only
Researchers considering extended protocols should be aware that this safety gap exists and should monitor for unexpected effects in tissues where NNMT has normal physiological functions
