Discussion 1) In order to determine whether AngIV is involved in the development of Alzheimers, the research team of Sun et al detected the baseline levels of AngIV in both wild type and APP/PS1 mice

Regular health monitoring Baseline testing before starting: Complete blood count (CBC) Comprehensive metabolic panel (liver, kidney function) Fasting glucose and insulin IGF-1 levels Thyroid panel (TSH, T3, T4) Follow-up testing: Every 3-6 months while using peptides Immediately if concerning symptoms Compare to baseline What to monitor: Blood sugar regulation Liver and kidney function Thyroid function IGF-1 levels (shouldn't be excessively elevated) Lipid profile When to stop: Any concerning blood markers Persistent side effects Signs of organ stress Unusual symptoms Cycling and breaks For growth hormone peptides: CJC-1295 + Ipamorelin: Can use 3-6+ months continuously GHRP-6: Cycle 8-12 weeks, break 4-8 weeks Hexarelin: Cycle 4 weeks, break 4+ weeks (not recommended for most) For healing peptides: BPC-157: Can use continuously TB-500: Can use continuously or cycle 8-16 weeks on, 4-8 weeks off GHK-Cu: Can use continuously Why breaks matter: Prevent receptor desensitization Allow natural hormone production to recover Reduce long-term risk Reset tolerance See peptide cycle planning guide and can you cycle different peptides
