IGF-1 LR3 Australia – Long Acting IGF-1 Research Peptide | AusBioLabs
Buy IGF-1 LR3 in Australia – IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1. In fact, it has an extra 13 amino acids and one changed residue. Because of these changes, it binds far less to IGF binding proteins, so researchers study it in laboratory cell growth work.
In the lab, scientists use IGF-1 LR3 only for in vitro studies. For example, they examine IGF-1 receptor binding, cell growth, and protein synthesis. Overall, AusBioLabs supplies premium research-grade IGF-1 LR3 strictly for qualified laboratory work.
Key Highlights
- Purity: >99% (Third party HPLC & MS Tested)
- Form: Lyophilised Powder
- Intended Use: Strictly for in vitro laboratory research only. Not for human consumption.
- Shipping: Fast Sydney/Melbourne Dispatch via Australia Post Express
What Is IGF-1 LR3?
IGF-1 LR3 is an 83 amino acid peptide, built from native IGF-1. First, it swaps one residue at position three for arginine. Then, it adds a 13-amino acid tag at the start. As a result, it lasts much longer than standard IGF-1 in study conditions.
Researchers value IGF-1 LR3 because it avoids IGF binding proteins. Moreover, this raises its potency in cell models. In short, this makes it a strong tool in growth factor research.
Research Applications (In Vitro / Laboratory Only)
- IGF-1 Receptor Signalling: First, researchers study how IGF-1 LR3 binds and activates the IGF-1 receptor.
- Cell Proliferation: In addition, scientists examine its effect on cell growth in culture.
- Reduced IGFBP Binding: Also, labs explore how its low IGFBP binding extends activity.
- Muscle Cell Research: Moreover, teams use it in vitro to probe myoblast and muscle cell behaviour.
- Comparative Growth Factor Studies: Finally, IGF-1 LR3 serves as a long-acting benchmark against native IGF-1.
Storage & Handling
- To begin, store the powder in a cool, dry place below 25°C, and keep it away from light.
- In addition, for longer storage, hold it at -20 °C.
- Next, reconstitute with bacteriostatic water under sterile lab conditions.
- Finally, avoid repeated freeze-thaw cycles.

Frequently Asked Questions
What do researchers use IGF-1 LR3 for?
Scientists use IGF-1 LR3 only for in vitro and laboratory studies. For example, they explore IGF-1 receptor signalling, cell proliferation, protein synthesis, and muscle cell behaviour. Above all, it is not for human or animal use.
How is IGF-1 LR3 different from native IGF-1?
IGF-1 LR3 carries two changes. First, it swaps one residue for arginine at position three. Then, it adds 13 amino acids at the start. Therefore, it lasts longer and binds to IGF binding proteins less in study models.
How do I store and reconstitute IGF-1 LR3?
IGF-1 LR3 ships as a lyophilised powder. First, in a sterile lab, researchers usually mix it with bacteriostatic water. Then store the powder below 25°C and away from light, or store it at-20°C for long-term storage. Finally, avoid repeated freeze-thaw cycles.
Can I buy IGF-1 LR3 in Australia for research?
Yes. AusBioLabs sells IGF-1 LR3 only as a research chemical for qualified laboratory use. However, it is not approved for human, medical, veterinary, or household use. Therefore, the buyer takes full responsibility for safe and compliant handling.
Disclaimer: Use this product strictly for qualified laboratory research only. It is not for human consumption, medical, veterinary, or household use. The buyer takes full responsibility for proper handling and use.
