Peptides IGF1 LR3 (1 mg)

We offer peptides for sale as Peptides IGF1 LR3 (1 mg). IGF1 LR3 is a modified insulin-like growth factor-1, and this Polypeptide listing supplies it at 1 mg. The LR3 designation, Long Arg3, refers to an N-terminal extension and an arginine substitution that together alter how the peptide interacts with IGF-binding proteins. That modification is the identity of the compound, not a strength grade, and it is the reason a plain IGF-1 product is not the same item.

IGF-1 signals through the IGF-1 receptor and is involved in growth, differentiation and metabolic regulation. In circulation most of it is bound to binding proteins, principally IGFBP-3, which limit access to receptors. LR3's reduced binding-protein affinity is what interests researchers: it changes the balance between bound and free peptide in experimental systems.

Where it sits in the axis

IGF-1 is downstream of growth hormone, produced largely in the liver in response to GH, and it also acts locally in tissue. That makes it a different molecule from a GHRH analogue or a ghrelin-receptor secretagogue, both of which influence GH release rather than supplying a growth factor. It is also not insulin, despite the name.

The 1 mg quantity is the labelled amount for the presentation, and the LR3 name is what distinguishes it from other IGF variants.

Structurally, LR3 carries an arginine in place of the glutamic acid at position three and an additional thirteen residues at the N-terminus, giving an 83-amino-acid chain. That combination reduces its affinity for IGFBP-3. Reduced binding distinguishes the analogue from IGF-1, but does not by itself establish a longer circulating half-life. The 1 mg figure is the labelled amount; the LR3 suffix is the part of the name that specifies the analogue.
