Muscle Growth Stack

Studied for: GH axis signaling, lean mass development, and tissue growth models

The Muscle Growth Stack includes three of the most widely researched peptides in muscle-focused and GH-related study models. It targets upstream growth hormone signaling and downstream IGF-1 pathways involved in tissue repair, protein synthesis, and performance recovery.

This stack supports research into:

• GH pulse stimulation and frequency modulation
• IGF-1 pathway activation in hypertrophy models
• GH/GHRP synergy and receptor signaling cascade analysis

This stack includes:

• CJC-1295 (DAC or no DAC) – 5mg
  A growth hormone–releasing hormone (GHRH) analog studied for its ability to stimulate
  endogenous GH release in both acute and sustained contexts, depending on the DAC
  variant. CJC is commonly evaluated in body composition and aging-related models.
• Ipamorelin – 5mg
  A GHRP studied for its selective GH-releasing effect without significant cortisol or
  prolactin spikes. It is often paired with CJC-1295 to explore synergistic GH pulse
  enhancement in tissue growth models.
  
• IGF-1 LR3 – 1mg
  An extended analog of IGF-1, researched for its ability to bind IGF-1 receptors with
  increased potency and half-life. It is studied in models involving cellular proliferation, muscle regeneration, and wound healing.

Why this combination?
Together, these peptides cover the entire GH-to-IGF axis. CJC and Ipamorelin initiate GH pulses, while IGF-1 LR3 supports anabolic signaling and tissue responsiveness. This makes the stack valuable for full-spectrum muscle and performance-based preclinical models.
