Sermorelin stimulates your pituitary to produce its own growth hormone rather than flooding your system with synthetic HGH — that distinction is real and meaningful. Because GH release remains pulsatile and pituitary-regulated, you avoid the supraphysiologic spikes that cause acromegaly-like side effects. But "all the anti-aging benefits" is a giant unsupported claim. The anti-aging literature on GH secretagogues in healthy adults is thin: mostly small trials, mostly short duration, mostly showing modest improvements in body composition and sleep quality. Longevity endpoints? Never studied. If you have documented GH deficiency, the risk/benefit math may work. If you are a healthy 45-year-old who saw an ad, you are paying for a plausible mechanism dressed up as a guarantee.
