We offer peptides for sale as IGF-1 LR3 1 mg. IGF-1 LR3 is an engineered analogue of insulin-like growth factor 1, listed here as a 1 mg Peptide Sciences vial. The modifications are the substance: LR3 exists to escape the binding proteins that normally restrain IGF-1, and that single design decision explains why it is studied apart from the native hormone.
What the LR3 changes do
Two structural edits define the analogue. An N-terminal extension lengthens the chain, and an arginine substitution at position 3 lowers affinity for IGF-binding proteins. Reduced binding to IGF-binding proteins changes the analogue's interaction with those proteins. It does not by itself establish slower clearance or a longer circulating half-life than unmodified IGF-1. The receptor itself is unchanged: signalling still runs through the IGF-1 receptor and not through the growth hormone receptor.
That receptor sits downstream of growth hormone but is a separate target, and LR3 is not a secretagogue. Research interest covers cellular proliferation and differentiation, protein metabolism and glucose handling, all ordinary IGF-1 receptor themes rather than proof of a particular physical result. Describing a pathway is not the same as predicting an outcome for a person. A receptor mechanism does not specify an individual's physical response.
This presentation supplies 1 mg in one container. IGF-1 DES is a different variant with a different structure and its own listing, so the full name, LR3 included, is what identifies the right product. A shortened label is not a safe shorthand when two variants of the same growth factor are being compared side by side. The number on the vial is the other half of the check.
