Description
Receptor Grade IGF-1 LR3 (100mcg) – Grey peptides.
Receptor Grade IGF-1 LR3 (100mcg) is a synthetic analog of human IGF-1 used in advanced research. Modified with a 13-amino-acid extension, IGF-1 LR3 lasts 20–30 hours in the body – far longer than native IGF-1. This receptor-grade peptide binds the IGF-1 receptor with normal affinity but evades most binding proteins (IGFBPs), making it roughly three times more potent than regular IGF-1.
China Grey Peptides provides lab-tested, high-purity IGF-1 LR3 (100mcg) to researchers in the USA and worldwide. Each 100mcg vial is batch-verified for purity and consistency, with a detailed Certificate of Analysis for every lot. http://bing.com
What is IGF-1 LR3 (Long-R3 IGF-1)?
- Analog Structure: IGF-1 LR3 (Long-R3 IGF-1) is an 83-amino-acid analog of insulin-like growth factor-1. It has an arginine substitution at position 3 and a 13-amino-acid N-terminal extension.
- Extended Activity: These modifications significantly lengthen its half-life and reduce binding to IGF binding proteins.
- Enhanced Potency: IGF-1 LR3 retains IGF-1 receptor binding but circulates much longer, enhancing its effect in experiments.
- Signaling Pathways: In cells, IGF-1 LR3 triggers anabolic signaling (PI3K/Akt, MAPK) that boosts protein synthesis, cell growth, and nutrient uptake.
Research Uses and Benefits of Receptor Grade IGF-1 LR3 (100mcg)
- Muscle & Tissue Studies: IGF-1 LR3 stimulates muscle protein synthesis and cell proliferation, making it ideal for muscle growth and repair studies.
- Metabolic Research: Studies show IGF-1 LR3 can significantly increase glucose uptake in muscle/adipose cells, valuable for metabolism research.
- Cell Culture Supplement: As a high-potency analog, IGF-1 LR3 supports stronger cell growth at lower doses than standard IGF-1.
- Anti-Aging Models: Its role in cellular regeneration and collagen support makes IGF-1 LR3 useful in aging and regenerative studies.
- Growth Factor Research: Researchers use this peptide to study IGF receptor signaling pathways and growth factor interactions.

FAQ – Receptor Grade IGF-1 LR3 (100mcg)
Q: What does “Receptor Grade” mean?
A: It indicates the highest purity (≥99%). Receptor Grade IGF-1 LR3 is more pure than standard research grade, offering consistent potency. Our COAs verify this purity.
Q: How is purity verified?
A: Each batch undergoes independent HPLC and mass spec. The COA includes the purity percentage (typically 99%+) and confirms the peptide’s identity.
Q: Is IGF-1 LR3 legal to buy?
A: Yes. IGF-1 LR3 is legal for laboratory research use in the USA. It is not FDA-approved for medical applications.
Q: Can I order in bulk?
A: Yes. We offer bulk quantities and wholesale pricing for qualified buyers. Please visit our Bulk Orders page or contact us for details.
Q: What is shelf life?
A: When stored properly at -20°C, IGF-1 LR3 (100mcg) is stable for months. Avoid repeated freeze-thaw cycles after reconstituting.
