IGF-1 LR3
Long-acting IGF-1 for growth and hyperplasia
Growth, hyperplasia
Key Benefits
- Extended half-life for sustained activity
- Enhanced protein synthesis signaling pathways
- May support muscle fiber development
- Reduced binding protein interference
- Improved bioavailability over native IGF-1
- Supports cellular growth processes
- Activates key anabolic pathways
Build Muscle While Your Body Repairs Itself
Most growth factors burn out fast, leaving you with a brief window of anabolic activity. IGF-1 LR3 stays active for over 20 hours, giving your muscles sustained growth signals around the clock. It's like having your body's natural muscle-building machinery working overtime, even while you sleep.

About IGF-1 LR3
IGF-1 LR3 is an enhanced version of your body's primary growth factor, engineered to avoid the binding proteins that normally shut down IGF-1 within minutes. This gives you sustained anabolic signaling that promotes both muscle fiber growth and the creation of new muscle cells through extended activation of key growth pathways.
Who It's For
Ideal for individuals seeking consistent muscle development and body composition improvements through optimized growth factor signaling. The extended half-life makes it particularly valuable for protocols focused on sustained anabolic states rather than brief growth windows. Works synergistically with training and recovery protocols to maximize tissue development over time.
Research Background
IGF-1 LR3 represents a significant advancement in growth factor research, designed to overcome the limitations of naturally occurring IGF-1. The primary challenge with native IGF-1 is its extremely short half-life and rapid inactivation by binding proteins in the blood. Researchers developed LR3 by modifying the original IGF-1 structure to create a more stable and longer-lasting version that maintains biological activity for extended periods.
The peptide works through the well-established IGF-1 signaling pathway, which is fundamental to growth and development throughout life. Key research areas include: 1) Muscle growth and regeneration - examining how enhanced IGF-1 signaling promotes both muscle fiber growth and the creation of new muscle cells, 2) Metabolic effects - studying impacts on protein synthesis, glucose metabolism, and fat utilization, and 3) Therapeutic applications - investigating potential treatments for muscle wasting conditions and age-related muscle loss. While animal studies have shown promising results for muscle development and body composition improvements, human research remains limited, making this an active area of scientific investigation.

CJC-1295 / Ipamorelin
CJC-1295 and Ipamorelin are designed for clients who want measurable performance, recovery, and longevity benefits—without crossing the line into hormone replacement or system shutdown. This is not synthetic HGH and it’s not a short-term hack. It’s a disciplined, physiology-first approach that restores the body’s own growth hormone signaling, which naturally declines with age, stress, poor sleep, and overtraining. CJC-1295 works upstream at the pituitary level, enhancing the quality, duration, and consistency of natural GH release, while Ipamorelin acts as a precision trigger—stimulating GH without the cortisol spikes, prolactin elevation, or hunger issues associated with older compounds. Together, they create smoother, more youthful GH pulses that the body actually knows how to use. From a client experience standpoint, this shows up where it matters: deeper, more restorative sleep; faster recovery between workouts or long workdays; improved fat metabolism; better skin and tissue quality; and a noticeable improvement in overall resilience. There’s no suppression of natural production, no dependency risk, and no hormonal rollercoaster—making it appropriate for long-term use and scalable protocols. For many clients, this stack becomes the foundation layer they build everything else on, because it improves how the body repairs, adapts, and recovers across the board. In short, this is growth hormone optimization for adults who play the long game—subtle, sustainable, and designed to deliver compounding returns over time.
