Common side effects (affect 10-30% of users): Growth hormone-related peptides (CJC-1295, Ipamorelin, etc.): Water retention (mild, temporary) Joint pain (usually temporary adaptation) Carpal tunnel-like symptoms (rare) Numbness/tingling in extremities (rare) Increased hunger (GHRP-6, GHRP-2) Lethargy initially (body adjusting) Healing peptides (BPC-157, TB-500): Headaches (occasional, mild) Nausea (rare) Dizziness (rare) Increased body hair growth (TB-500) Injection-related: Site reactions (redness, minor pain) Bruising (improper technique) Infection risk (if sterility not maintained) Rare but possible: Blood sugar changes (monitor if diabetic) Prolactin increase (with some GH peptides) Tachyphylaxis (reduced effectiveness over time with some peptides) What's notably absent: No testosterone suppression No cardiovascular remodeling No liver stress No hormonal disaster No PCT required No infertility issues Long-term safety: Growth hormone peptides mimic natural pulses (safer than exogenous GH) Healing peptides have excellent long-term safety profiles No evidence of organ damage with proper use Can be used for extended periods Head-to-head safety comparison Hormonal disruption: Steroids: 10/10 severity (guaranteed shutdown) Peptides: 1/10 severity (minimal hormonal impact) Cardiovascular risk: Steroids: 8/10 severity (significant risk increase) Peptides: 2/10 severity (minimal concerns) Liver toxicity: Steroids: 7/10 severity (oral steroids especially) Peptides: 0/10 severity (no liver impact) Reversibility of side effects: Steroids: 5/10 (some permanent damage possible) Peptides: 9/10 (almost everything reverses) Need for ancillary drugs: Steroids: Extensive (AI, SERM, hCG, PCT drugs, BP meds) Peptides: Minimal (maybe vitamin B6 for prolactin if needed) The safety profile of peptides is vastly superior

That said, he references actual studies, and the videos are entertaining
