All Peptide Comparisons

12 head-to-head comparisons.

• AOD-9604 vs Semaglutide — The growth hormone fragment that promised fat loss vs the GLP-1 that actually delivers it.
• BPC-157 Oral vs Injectable — Same peptide, two delivery routes. Where you want it to work determines how you take it.
• BPC-157 vs TB-500 — The two recovery peptides everyone asks about. Different mechanisms, often stacked together.
• CJC-1295/Ipamorelin vs Tesamorelin — Two approaches to growth hormone secretion. One's a broad anti-aging stack, the other targets belly fat with FDA backing.
• GHK-Cu Topical vs Injectable — Same copper peptide, different depths. Surface-level skincare vs systemic anti-aging — choose your adventure.
• MOTS-c vs SS-31 — Two mitochondrial peptides, two completely different playbooks. One signals, the other shields.
• Ozempic vs Wegovy — Same exact drug. Different label, different dose, different insurance code. Welcome to pharma branding.
• Pen vs Vial — The GLP-1 format question that actually matters more than most people think.
• Selank vs Semax — Russian-developed nootropic peptides. One calms you down, the other lights you up. Both go up your nose.
• Semaglutide vs Retatrutide — The current king versus the triple-agonist that might dethrone it. One's approved, one's not.
• Semaglutide vs Tirzepatide — The two GLP-1 heavyweights, head to head. Same family, different firepower.
• Tirzepatide vs Retatrutide — Dual agonist vs triple agonist. Both from Eli Lilly. One's available, one could be the endgame.
