IGF-1 LR3 1mg

IGF-1 LR3 is a long-acting analogue of insulin-like growth factor 1, engineered with an extended amino acid sequence to reduce binding to IGF-binding proteins, studied within Australian peptide research for its receptor-binding properties.

IGF 1 LR3 peptide is the same compound as IGF-1 LR3 — the hyphen is often dropped, and it also appears written IGF1 LR3 or Long R3 IGF-1. All refer to the analogue PhaseOne supplies in 1mg vials for laboratory research use only.

LR3 stands for Long Arg3 — "Long" for the extended 13-amino-acid sequence added at one end, and "Arg3" for the arginine substitution at the third position. Together those two modifications reduce binding to IGF-binding proteins, which is what distinguishes it from native IGF-1.

No — they are different molecules at different points in the same pathway. HGH is growth hormone itself; IGF-1 is produced downstream in response to it, and IGF-1 LR3 is a modified analogue of that. They are related but not interchangeable, and PhaseOne does not supply HGH.

They sit at opposite ends of the same axis. CJC-1295 and Ipamorelin are secretagogues studied for stimulating the body's own growth hormone release; IGF-1 LR3 is an analogue of the downstream product of that release. One acts upstream, the other is the downstream molecule itself. PhaseOne supplies all three. (!) View our CJC-1295 No DAC, Ipamorelin or the CJC-1295 + Ipamorelin blend.

Tesamorelin is a GHRH analogue acting upstream on the growth hormone axis, while IGF-1 LR3 is an analogue of the downstream growth factor. Same pathway, different points in it — which is why the two appear in related research rather than as substitutes. (!) View our Tesamorelin.

PhaseOne ships IGF-1 LR3 Australia-wide for research use, dispatched locally with tracking, in 1mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity.

Yes — PhaseOne has IGF 1 LR3 for sale online in 1mg vials, shipped Australia-wide. IGF-1 is supplied in several analogue forms, so it is worth confirming a listing specifies LR3 rather than native IGF-1 or another variant, and that a batch Certificate of Analysis is provided.

PhaseOne prices IGF-1 LR3 at A$103.99 for a 1mg vial, with the batch Certificate of Analysis included at no extra cost. Current pricing is shown on this page.

No. IGF-1 LR3 is not registered on the ARTG and is not approved for supply as a medicine in Australia, so Chemist Warehouse and other Australian chemists do not stock it. It is supplied as a research compound through research suppliers instead.

The LR3 modification extends the molecule's research half-life relative to native IGF-1, making it a distinct research tool rather than a direct substitute.

Unreconstituted IGF-1 LR3 should be stored refrigerated and protected from light, and is commonly reconstituted with bacteriostatic water immediately prior to research use. Read our reconstitution guide.

Each PhaseOne batch is independently verified by third-party HPLC analysis, with a Certificate of Analysis available for every order shipped across Australia.

IGF-1 LR3 is currently supplied in 1mg vials, shipped Australia-wide with full batch documentation.
