Identify gaps in the literature and ongoing research directions Key gaps include a lack of large, controlled clinical trials, unclear optimal dosing and delivery for reproductive targets, limited long-term safety data for systemic use, and few mechanistic human studies linking molecular changes to fertility outcomes

This is the most crucial and most concerned issue

Match goal to category: Injury = Healing peptides Build muscle = Growth hormone peptides Lose fat = Fat loss peptides Look younger = Anti-aging + skin peptides Better sex = Sexual health peptides Sharper mind = Cognitive peptides Step 2: Consider your experience level Beginners start with: BPC-157 (healing) CJC-1295/Ipamorelin (muscle/anti-aging) Semaglutide (fat loss, if you can get prescription) Intermediate users can add: TB-500 (healing) AOD 9604 (fat loss) PT-141 (sexual health) Advanced users explore: IGF-1 LR3 (muscle) Multiple peptide stacks Specialty peptides for specific conditions Step 3: Evaluate safety profile Safest peptides (extensive use, minimal sides): BPC-157 TB-500 CJC-1295 Ipamorelin GHK-Cu Use with caution (more sides or less data): GHRP-6 (prolactin increase) Hexarelin (desensitization, cortisol) IGF-1 LR3 (hypoglycemia risk) Melanotan II (permanent tanning, nausea) Step 4: Consider practical factors Injection frequency: Once weekly: Semaglutide, Tirzepatide Daily: AOD 9604, Epithalon (during cycles) Twice daily: BPC-157, KPV 2-3x daily: GHRP-6, GHRP-2 Choose based on your compliance: If you won't inject 3x daily consistently, pick different peptide
