Product Overview
Compound: IGF‑1 LR3 (Long R3 Insulin-Like Growth Factor‑1), synthetic analogue with a 13‑aa extension and an arginine substitution at position 3 :contentReference[oaicite:1]{index=1}.
Form: 1 mg lyophilized powder, USA‑manufactured, ≥99 % purity (Receptor Grade).
For laboratory research use only—NOT for human or veterinary use.
Batch-tested ≥99% purity via HPLC. Full COA available upon request—email providers@theratideusa.com.
- Extended activity: LR3 variant exhibits low affinity for IGF-binding proteins, resulting in ~20–30 h half-life—significantly longer than native IGF‑1 :contentReference[oaicite:2]{index=2}.
- Muscle growth & hypertrophy: Promotes both hypertrophy and hyperplasia of muscle cells, surpassing standard IGF‑1, and supports satellite cell activation :contentReference[oaicite:3]{index=3}.
- Fat metabolism & myostatin inhibition: Enhances lipolysis, improves insulin sensitivity, and may inhibit myostatin pathways :contentReference[oaicite:4]{index=4}.
- Organ & fetal growth: In sheep, LR3 IGF‑1 promotes fetal organ development and muscle proliferation :contentReference[oaicite:5]{index=5}.
- Cancer risk: Elevated IGF‑1 signaling has been associated with increased risk of certain cancers :contentReference[oaicite:6]{index=6}.
All findings are from cell culture, animal, and observational studies; human efficacy and safety not fully established.
How is IGF‑1 LR3 used in research?
Typically reconstituted and injected (e.g., IM, IV) in cell culture and animal models to study tissue growth, metabolism, and receptor signaling.
Benefits?
Known for long-lasting anabolic effects, muscle regeneration, fat metabolism enhancement, and potential metabolic health benefits.
Risks?
Potential side effects include hypoglycemia, edema, joint pain, possible increased tumor risk—monitor metabolic parameters in study settings :contentReference[oaicite:7]{index=7}.
Is it banned?
Yes—IGF‑1 LR3 is prohibited by World Anti-Doping Agency and other sports authorities :contentReference[oaicite:8]{index=8}.
For research use only—NOT intended for human or veterinary use, or as a dietary supplement.
