Why sermorelin patients notice sleep first
The pulsatile release of growth hormone is deeply tied to deep sleep. Here's the mechanism, in plain English.
Growth hormone isn't released in a steady drip. It comes in pulses, and the largest pulse of the day happens during the first stage of deep, slow-wave sleep. Sermorelin encourages that pulse to be a little larger, a little more reliable.
The subjective change
Most patients don't notice body composition first. They notice sleep — deeper, less interrupted, more restorative. Recovery from training follows a few weeks later. Body composition is a longer arc.
Why it isn't HGH
Sermorelin doesn't replace growth hormone. It nudges your own pituitary to release its own, in its natural rhythm. That distinction matters both for safety and for how the treatment feels day to day.
