We offer peptides for sale as Peptides IGF-1 LR3 (receptor level) 1 mg. IGF-1 LR3 is a modified form of insulin-like growth factor 1, and this Peptide Sciences vial carries 1 mg under a receptor-level designation. It is a growth-factor receptor ligand, not an androgen, and the Long Arg3 modification in its name is the structural detail that matters most when comparing it with ordinary IGF-1. The listing is a single 1 mg vial, so the amount is the vial content rather than a kit total.
What Long Arg3 changes
The LR3 change is an arginine substitution at position 3 together with an N-terminal extension, which reduces the peptide's tendency to bind IGF-binding proteins in experimental systems. Less binding-protein sequestration means more of the peptide is available to interact with the IGF-1 receptor, and that receptor is associated with cellular growth, differentiation and metabolic regulation. IGF-1 signalling also intersects with glucose physiology, which is why broad anabolic promises are an incomplete way to describe the pathway.
What "receptor level" means here
The receptor-level phrase is a grade designation carried in the product name, not a quantity and not a second active ingredient. It does not turn the item into a different molecule, and it does not by itself establish a special delivery system or a superior response. The ingredient is IGF-1 LR3 at 1 mg, and the LR3 identity should stay attached to that figure in any comparison. IGF-1 LR3 is not IGF-1 DES, which is truncated differently, and neither is it growth hormone; similar family names hide different structures, and the two are separate listings rather than strengths of one product.
