What is IGF-1 LR3?
IGF-1 LR3 is an 83-amino-acid analog of endogenous insulin-like growth factor 1, engineered with an N-terminal extension that reduces binding to IGFBPs — extending its half-life from ~20 minutes to ~20–30 hours and dramatically increasing free bioactivity.
Every KINETYX vial is filled in a controlled cleanroom and sealed with tamper-evident packaging. Batch documentation includes identity confirmation, HPLC purity analysis and concentration verification.
