How it works
Signal
Sermorelin is given as a single subcutaneous injection at bedtime — the timing lines it up with your body's natural nighttime growth-hormone pulse.
Cellular response
Sermorelin binds GHRH receptors in the pituitary gland, triggering the release of your own (endogenous) growth hormone. It maintains the natural pulsatile GH-release pattern and preserves the hypothalamic–pituitary feedback loop, so output stays self-limiting.
Outcome
Over the following weeks most people notice deeper sleep first (weeks 1–2), then steadier daytime energy and faster recovery (weeks 2–4), then body-composition changes — less belly fat, more lean tone (weeks 4–8). Benefits tend to hold, and research suggests pituitary output can improve over time.
