Tesamorelin makes more sense if: Your main goal is losing stubborn belly fat or body recomposition You're already exercising and eating well but can't move the needle on your midsection You want the strongest clinical evidence behind your protocol You're comfortable managing more noticeable side effects in exchange for more aggressive results You want faster, more visible changes in body composition Sermorelin makes more sense if: You're seeking broad GH optimization across multiple areas (sleep, recovery, skin/hair, energy, body comp) You're new to peptide therapy and want a gentler introduction You're a woman (estrogen amplifies the IGF-1 response, making the lower intensity more than sufficient) You prioritize minimal disruption and a mild side effect profile Your goals are more about sustained vitality and anti-aging than aggressive fat targeting You want a simple daily protocol without cycling on and off The honest answer for most people If you have one specific, measurable goal losing visceral fat and the clinical data supporting that outcome matters to you, tesamorelin is the more targeted tool
