Product Overview
Product Overview
IGF-1 LR3 Overview
IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic analogue of IGF-1, a naturally occurring growth factor in the human body. IGF-1 is an important mediator of growth hormone (GH) effects, promoting muscle growth, repair, and regeneration. The “Long R3” modification significantly increases its half-life and bioavailability, making it more potent and longer-acting than natural IGF-1.
Peptide Structure
Research Applications
In research studies, IGF-1 LR3 has demonstrated potential in:
- Promoting muscle hypertrophy and preventing atrophy in animal models
- Enhancing wound healing and tissue repair
- Improving recovery following nerve injuries
- Investigating its role in neuroprotection and cognitive function
Due to its extended half-life, IGF-1 LR3 remains active in the body for longer periods, making it a preferred variant for research compared to native IGF-1.
Longevity Research
IGF-1 LR3 is also under investigation for its potential role in longevity and age-related diseases. Research has explored its ability to mitigate sarcopenia (age-related muscle loss), improve bone density, and contribute to overall tissue maintenance and regeneration in aging populations.

Storage Instructions
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months. Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you're ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4°C (39°F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer-term storage (several months to years), it is preferable to store peptides in a freezer at -80°C (-112°F). When storing peptides for months or even years, freezing is optimal to preserve the peptide’s stability.
