How long does Sermorelin take to work?
In the first week of Sermorelin, sleep deepens. Vivid dreams. Around week 4, recovery improvements. IGF-1 climbing modestly. By week 8, body comp and skin changes for users in a clean diet. Response varies between people, this is the commonly reported pattern, not a guarantee.
