IGF-LR3 (Insulin-Like Growth Factor Long R3) is a synthetic analogue of the naturally occurring growth peptide IGF-1. It is manufactured in peptide laboratories and supplied in high-purity lyophilised powder form for investigational research.
IGF-LR3 has been engineered with an extended amino-acid sequence that gives it a significantly longer half-life than standard IGF-1, making it valuable for controlled experimental models. Scientific investigations have focused on its ability to bind IGF-1 receptors and remain active in cellular systems for prolonged study periods.
Available research data, primarily from in-vitro and animal studies, indicates IGF-LR3 may assist researchers examining:
Because of its extended activity profile, IGF-LR3 is widely utilized by private research institutions exploring non-therapeutic applications related to performance and tissue-recovery experiments.performance and recovery research.
