Growth Hormone Stack (CJC-1295/Ipamorelin + IGF-1 LR3)
This Growth Hormone stack combines CJC-1295/Ipamorelin with IGF-1 LR3 for GH signaling, sleep support, and muscle growth research. The peptide names are in the title so this version is easy to distinguish from other “growth” stacks in the library.
Growth Hormone Stack Quick Overview
CJC-1295/Ipamorelin
GH release support
200 mcg each nightly
IGF-1 LR3
Anabolic and recovery signaling
30–60 mcg daily
What Is the Growth Hormone Stack
This stack combines a GH secretagogue pairing with an IGF-focused component. CJC-1295/Ipamorelin is often discussed for stimulating the body's own growth-hormone pulses, while IGF-1 LR3 is discussed more directly in muscle-recovery and growth signaling conversations.
Because there are multiple growth-oriented stacks in the planner, this page uses the exact peptide names in the title. That makes it clear this is the GH-plus-IGF version, not a different performance or bulking stack.
How the Stack Works
CJC-1295
GHRH analog role — is commonly discussed for growth-hormone release support
Longer stimulation pattern — is used to support GH signaling over time
Sleep pairing — is frequently positioned around bedtime routines
Ipamorelin
Selective secretagogue — is discussed for GH release with fewer off-target hormone effects
Bedtime use — is commonly paired with fasted or pre-sleep administration
Recovery interest — is often included for sleep and recovery support
IGF-1 LR3
Downstream signaling — is discussed for muscle growth and repair pathways
Post-workout use — is commonly positioned after training sessions
Recovery amplification — may extend the stack beyond GH release alone
The stack pairs upstream GH signaling with downstream IGF-style recovery signaling. That is why it is often treated as a stronger growth-oriented option than secretagogues alone.
Benefits
Growth-hormone release support
Sleep and nighttime recovery positioning
Muscle growth and post-training recovery support
More explicit growth signaling than a secretagogue-only stack
Clear differentiation from other growth-named stacks
Typical Protocol
1–8
9–12
Off or deload
A common structure is 8 weeks on followed by 4 weeks off. For the secretagogue side of the stack, see the CJC-1295 results timeline and Ipamorelin results timeline.
Results Timeline
Week 1–2: Sleep quality, recovery, and training readiness are early checkpoints
Week 3–4: Users often look for improved recovery capacity and gym performance
Week 5–8: Body-composition, muscle-growth, and recovery outcomes are the longer-range focus
Changes in body composition usually trail behind sleep and recovery changes. Use the component guides above for timing context rather than expecting uniform week-by-week results.

FAQs
This Growth Hormone stack combines CJC-1295/Ipamorelin with IGF-1 LR3. The page title uses the exact compounds so it is clearly differentiated from other similarly named growth or performance stacks.
CJC-1295/Ipamorelin is commonly discussed for GH-release support, while IGF-1 LR3 is discussed for downstream anabolic and recovery signaling. Together they are often framed as a growth-and-recovery pairing.
Not exactly. It may overlap with performance-oriented goals, but this page frames the stack around growth-hormone signaling, sleep, recovery, and muscle-support research rather than a generic bodybuilding label.
A common range is 8 weeks on followed by 4 weeks off, especially when IGF-1 LR3 is part of the protocol. Actual timing varies by component, tolerance, and research goal.
No. Human evidence for the full combination is limited. Most stack logic comes from separate GH secretagogue and IGF-related literature rather than direct trials on the exact protocol.
