Long R3 IGF-1 analog
Vial Content
For laboratory & research use only — not for human or animal consumption. You must be 18+ to purchase.
Overview
IGF-1 LR3 (Long R3 IGF-1) is an 83-residue engineered analog of insulin-like growth factor 1. An arginine substitution at position 3 and a 13-residue N-terminal extension sharply reduce binding to IGF-binding proteins — the design that gives LR3 its extended activity and made it a standard tool in cell-culture and cellular-signalling research.
Native IGF-1 disappears from a system in minutes; LR3's long-acting profile holds working concentrations steady across the windows real protocols need. And because it is potent and used at low concentrations, small identity or purity errors are amplified — the data behind each vial matters more here than for almost any other peptide. Supplied lyophilized in 100 mcg and 1 mg vials.
Every batch is independently HPLC-tested and released at ≥99% main-peak purity, with the COA public before purchase — including the identity confirmation that distinguishes true LR3 from native IGF-1. Cold-chain delivery, tamper-evident packaging, and a unique REP-XXXX-XXXX-X first-scan code on every vial. For laboratory and research use only.
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
Ships within Egypt 1–3 business days via insulated courier.

FAQ
IGF-1 LR3 (Long R3) carries an arginine substitution and an N-terminal extension that reduce IGF-binding-protein binding, giving it a longer-acting profile used in cell-culture research.
Lyophilized 100 mcg and 1 mg vials, HPLC-verified at ≥99% purity, each with a batch-specific COA on the product page.
Orders ship in temperature-controlled packaging via insulated courier. Standard delivery is 1–3 business days from Cairo, within Egypt only.
Each vial's insert carries a unique code in the format REP-XXXX-XXXX-X. Enter it on the /verify page — the first scan stamps it verified; a later scan warns the code has already been used.
