Sermorelin, CJC-1295, or Ipamorelin - which should a beginner pick?

Updated 2026-05-04

For a true beginner, sermorelin is the gentlest start - one peptide, one nightly shot, fewest side effects. CJC-1295 (without DAC) plus Ipamorelin is the most popular intermediate stack because they hit two different growth-hormone pathways and the pulses last longer than sermorelin alone. Skip CJC-1295 with DAC for your first round - it has a much longer half-life and the side effect profile is harder to read. All three need to be injected at night, on an empty stomach.

IfIf you've never injected before
Thenthen start with sermorelin alone for 8-12 weeks before considering a stack
IfIf you've done at least one peptide cycle
Thenthen move to CJC-1295 (no DAC) + Ipamorelin together at night
IfIf you eat dinner late
Thenthen push the injection 2 hours after your last meal - food blunts the GH pulse
IfIf you start getting wrist tingling or numbness
Thenthen drop the dose and call your prescriber - that's an early water-retention sign
Key facts
  • Sermorelin is a 29-amino-acid GHRH analog with a short half-life (~10 minutes) and a clean side effect profile
  • Ipamorelin is a selective ghrelin-receptor agonist that triggers GH pulses without raising cortisol or prolactin
  • CJC-1295 without DAC has a 30-minute half-life; CJC-1295 with DAC has a multi-day half-life and produces a steady GH bleed instead of pulses
  • Stacking CJC-1295 (no DAC) with Ipamorelin is the most cited 'starter stack' in clinical commentary because the two work on different receptors
  • All three should be injected at night, fasted, to align with the body's natural GH pulse cycle
