About IGF-1 LR3
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified analog of IGF-1 with an extended half-life due to reduced binding-protein affinity.
Research has examined IGF-1 LR3 for IGF-1 receptor signalling, cellular proliferation, and growth pathway models. The LR3 modification is studied for greater bioavailability than native IGF-1.
Why researchers choose Midas
Every lot of IGF-1 LR3 is independently tested by an accredited third-party laboratory for identity (mass spectrometry) and purity (HPLC), and the Certificate of Analysis for your exact batch is published in our COA library — not available "on request." Learn how to read a COA before you buy from anyone.
Ships cold-chain from the US in plain, unbranded packaging with tracking. Free shipping over $150.
