About muscle growth peptides

Muscle-growth peptides include GH (growth hormone) secretagogues like Ipamorelin, CJC-1295, and Sermorelin. They prompt the body to release its own GH rather than introducing exogenous GH directly — different regulatory profile, different side-effect profile.

Researched both for hypertrophy and recovery, this category overlaps with Recovery & Healing. Reviewer feedback tends to focus on injection-site irritation and sleep changes more than visible body composition shifts.

What to know before buying

  • GH secretagogues are typically dosed pre-bed to align with natural GH pulse
  • Most are stacked (Ipamorelin + CJC-1295 is the classic combination)
  • Cycle length matters — most protocols run 8-12 weeks then break
