IGF-1 LR3 0.1mg
IGF-1 LR3 — a synthetic analog of insulin-like growth factor 1, engineered with an N-terminal extension and an arginine substitution studied for altered binding-protein affinity relative to native IGF-1. Investigated across rodent and cell-culture research models, including a 2025 study of intranasal LR3-IGF-1 in 5XFAD mice (Engel et al., J Alzheimers Dis — PMID 39610283). Lyophilized powder, research-grade. For Research Use Only. Not for human consumption.

Description
About this peptide
About This Compound
IGF-1 LR3 (Long R3 IGF-1) is a synthetic analog of human insulin-like growth factor 1, modified with a 13-amino-acid N-terminal extension and an arginine substitution at position 3. These modifications are studied for their effect on binding-protein affinity relative to native IGF-1, a property researchers have used across cell-culture and rodent models to extend the analog's presence in circulation for experimental purposes. Independent laboratories have applied LR3-IGF-1 across a range of research contexts, from neuroscience to lactation physiology to analytical chemistry.
Research Context
Engel et al., 2025 (Journal of Alzheimer's Disease) examined intranasal LR3-IGF-1 in 5XFAD mice, evaluating amyloid plaque remodeling and cognitive outcomes over a seven-month treatment period. Hadsell et al., 2008 (Journal of Endocrinology) studied LR3-IGF-1 administration in lactating mice, examining mammary gland signaling and gene expression alongside growth hormone and prolactin. Mongongu et al., 2021 (Drug Testing and Analysis) developed a mass-spectrometry method for detecting LongR3-IGF-1 and related analogs, validating detection windows in a rat administration model.
