Peptides Powder IGF 1-LR3

Description

IGF-1 LR3 (Long R3 Insulin-Like Growth Factor-1) is a synthetic, extended-half-life version of IGF-1. Its modified structure improves stability and potency, making it a popular choice in research focused on muscle growth, recovery, and cellular regeneration.

What is IGF-1 LR3?

IGF-1 LR3 (Insulin-like Growth Factor 1 Long R3) is a modified version of IGF-1, a peptide hormone that plays a key role in growth, development, and tissue repair. The "LR3" part of the name refers to a modification at the third amino acid of the peptide, which extends its half-life and enhances its biological activity.

●IGF-1 is a naturally occurring protein produced primarily in the liver, stimulated by growth hormone (GH). It is responsible for various growth and developmental processes in the body, such as cell regeneration, muscle growth, and bone health.

●LR3 Modification: In IGF-1 LR3, the substitution of the amino acid arginine at position 3 alters the peptide's structure, making it less likely to bind with IGF-binding proteins (IGFBPs). This modification means the peptide remains in its active form for a longer duration in the bloodstream, leading to an extended half-life and greater potency.

IGF-1 LR3 powder is typically the lyophilized (freeze-dried) form of the peptide, which requires reconstitution with sterile water or bacteriostatic water before use.

Clinical Data

Applications

IGF-1 LR3 is frequently studied for:

Muscle hypertrophy mechanisms

Cellular growth pathways

Recovery and tissue repair models

Performance and endurance adaptation

Anti-catabolic activity research

Key Features & Advantages

1. Enhanced Muscle Protein Synthesis

IGF-1 LR3 is valued in research for its ability to support lean muscle development, nutrient uptake, and anabolic activity.

2. Extended Half-Life

The LR3 modification significantly increases stability-lasting up to 20–30 hours, allowing longer activity compared to standard IGF-1.

3. Supports Recovery & Tissue Repair

Often used in studies involving muscle regeneration, collagen formation, and accelerated recovery after intense physical stress.

4. Increased Nutrient Delivery

Research shows IGF-1 LR3 can enhance glucose and amino acid transport, improving muscle fullness and performance adaptation.

5. Widely Used for Performance Research

Its stability, potency, and extended activity make IGF-1 LR3 a common peptide in performance-related investigations.

Stability & Storage Requirements

Store below –20°C for long-term stability

Short-term storage (1–2 weeks) possible at 2–8°C

Keep vial in a dry, dark environment

Avoid repeated freeze–thaw cycles to maintain integrity

Dosage

1 Standard Dosage

The dosage of IGF-1 LR3 can vary depending on individual goals, such as muscle growth, fat loss, or recovery. Standard dosages generally range between 20-100 mcg per day.

For Muscle Growth: 40-100 mcg daily.

For Fat Loss: 20-40 mcg daily.

For Recovery and Healing: 20-60 mcg daily.

It is important to note that individual responses to IGF-1 LR3 can vary, and it is recommended to start with a lower dose to assess tolerance before increasing.

2 Administration Method

IGF-1 LR3 is administered through subcutaneous injections. After reconstituting the powder with bacteriostatic water, it is typically injected into the fatty tissue of the abdomen or thigh.

Injection Frequency: Due to its long half-life, most users administer IGF-1 LR3 once daily, typically after a workout for muscle growth. Some users may opt for split doses to maintain more consistent levels of the peptide throughout the day.

3 Reconstitution

To reconstitute IGF-1 LR3 powder, it is necessary to add sterile or bacteriostatic water to the vial containing the peptide. Typically, the ratio is about 1-2 ml of water for each vial of IGF-1 LR3. After adding the water, gently swirl the vial to dissolve the peptide; do not shake vigorously, as this can degrade the peptide.
