IGF-1 LR3
Wholesale Long-Acting IGF-1 Analogue — GMP-Certified, ≥98% HPLC-Verified
IGF-1 LR3 (Long R3-IGF-1) is a synthetic 83-amino-acid analogue of human insulin-like growth factor 1 (IGF-1), modified with an arginine substitution at position 3 and a 13-amino-acid N-terminal extension to significantly reduce binding to IGF-binding proteins and extend its half-life. It is widely researched in performance, recovery, and tissue regeneration science.
Peptide Direct supplies wholesale IGF-1 LR3 manufactured under GMP and ISO 9001:2015 certified conditions, verified by HPLC analysis to ≥98% purity, and supplied with a Certificate of Analysis on every batch — for clinics, distributors, and wellness brands.
