When will I see first results on sermorelin?
Sleep improvement by week 2-3 (earliest sign). Energy boost by week 3-4. Visible strength/body composition changes by week 6-8. Full transformation by week 12.
Why do results take so long?
GH works via hormone signaling cascades. Protein synthesis upregulation takes days. Tissue remodeling (muscle gain, fat loss) takes weeks. Patience required.
Can results be faster with higher doses?
Yes. 1000-1500 mcg shows faster visible results (by week 5-6) than 500-700 mcg. Risk: higher side effect incidence.
Do results plateau after 12 weeks?
Yes. Most rapid improvements occur weeks 1-12. Plateau phase (slower gains) begins week 12-16. Cycling resets the response curve.
What if I don't see results by week 8?
Check: sleep 7-9 hours? Protein 1.6+ g/kg? Training 4+ x/week? Dose 700+ mcg? Most non-responders have lifestyle/dosing issues, not biological non-response.
How long do results last after stopping?
Muscle gains are retained if training continues. Fat loss partially persists. Sleep/energy revert within 1-2 weeks. About 50-70% of gains persist long-term if lifestyle maintained.
