We offer peptides for sale as IGF-1 LR3 Canada Peptides 1 mg. IGF-1 LR3 is a modified analogue of insulin-like growth factor 1, supplied by Canada Peptides as a 1 mg vial. The LR3 tag marks two structural changes, an N-terminal extension and an arginine substitution at position three, that alter how the peptide interacts with binding proteins. Those changes make it a distinct molecule from both IGF-1 and insulin.
Binding proteins set the rules
In circulation, most IGF-1 is bound to IGF-binding proteins, chiefly IGFBP-3, which extends its half-life and limits receptor access. The LR3 modifications reduce that binding, leaving more peptide available to the IGF-1 receptor. The receptor itself is a tyrosine kinase linked to growth, differentiation and metabolic signalling, so the analogue's profile follows from both its structure and the binding environment. That is also why the analogue is discussed in terms of availability rather than potency alone.
A different axis from GH peptides
IGF-1 is produced partly in response to growth hormone and mediates some GH effects, but it acts on its own receptor. That makes it a downstream growth factor rather than a secretagogue: GHRP and GHRH products encourage pituitary output, while IGF-1 LR3 supplies an analogue of the mediator itself. Neither relationship makes the two interchangeable in a comparison. They are related in the endocrine chain but distinct as products, which is why they are sold under separate names.
One milligram of lyophilised peptide, single ingredient. The small unit size reflects the potency of the compound class, and the milligram figure should be matched exactly when comparing IGF-1 products, since analogues and vial sizes vary and a familiar name says nothing about what is inside. That is the figure to quote when asking about availability.

When you buy IGF-1 LR3 from IronJuice Shop, you receive an original product supplied directly by its manufacturer.
Frequently Asked Questions
What is the active substance in IGF-1 LR3 Canada Peptides?
IGF-1 LR3 is a modified analogue of insulin-like growth factor 1, supplied by Canada Peptides as a 1 mg vial.
What mechanism should I understand before I buy IGF-1 LR3?
IGF-1 LR3 acts at the IGF-1 receptor, and its modifications reduce binding-protein affinity, leaving more peptide available to that receptor. In circulation, most IGF-1 is bound to IGF-binding proteins, chiefly IGFBP-3, which extends its half-life and limits receptor access.
What structural or composition features are described for peptides for sale?
One milligram of lyophilised peptide, single ingredient.
Which related-substance distinctions matter for peptides for sale here?
The LR3 tag marks two structural changes, an N-terminal extension and an arginine substitution at position three, that alter how the peptide interacts with binding proteins. Those changes make it a distinct molecule from both IGF-1 and insulin.
Which names identify the IGF-1 LR3 for sale offered here?
The product is IGF-1 LR3 Canada Peptides 1 mg.
Which brand identifies the IGF-1 LR3 for sale offered here?
This product is from Canada Peptides.
What amount is supplied with the IGF-1 LR3 for sale offered here?
1 mg of lyophilised IGF-1 LR3 as a single ingredient.
How can I check authenticity if I buy IGF-1 LR3 online?
Check the product's authenticity code on the manufacturer's official website after receipt. Keep the code with the batch and expiry details. Our peptides for sale range includes this product, supplied directly by its manufacturer.
