Strong cases for peptides: Weight loss and metabolic health : Tirzepatide and semaglutide are genuinely transformative for appropriate candidates Growth hormone deficiency : Secretagogues may benefit people over 40 with documented low GH (though actual GH replacement works better) Questionable cases: Acute injury recovery : BPC-157 and TB-500 might help, but evidence is thin and safety unknown General "enhancement" : Most peptides provide marginal effects with significant question marks Better alternatives for muscle growth: Instead of chasing unproven peptides, discuss these evidence-based options with a physician: Hormone replacement therapy : Testosterone for men
hCG is often used alongside testosterone replacement therapy to help maintain fertility and testicular function
