IGF-1 LR3 (Kit)
$500.00
IGF‑1 LR3 is a long‑acting research peptide studied for its potential in muscle growth, recovery, and cellular regeneration. Its enhanced stability and bioavailability make it a valuable compound for advanced scientific exploration.
IGF‑1 LR3 (Insulin‑Like Growth Factor‑1 Long Arg3) is a synthetic peptide engineered to extend the biological activity of natural IGF‑1. Through structural modifications, IGF‑1 LR3 demonstrates a significantly longer half‑life and reduced binding affinity to IGF‑binding proteins, allowing for greater bioavailability in laboratory studies.
