Receptor Grade IGF-1 LR3 (100mcg)

What is Receptor Grade IGF-1 LR3?

Insulin-like Growth Factor-1 Long Arg3 (IGF-1 LR3) is a synthetic analog of human IGF-1. The “Receptor Grade” designation is critical; it signifies a level of purification and biological activity intended for rigorous in vitro and in vivo testing. By substituting arginine for glutamic acid at the third position and adding a 13-amino acid extension at the N-terminus, this peptide exhibits a significantly higher potency than standard IGF-1.

This modification prevents the peptide from binding to inhibitory proteins, allowing it a much longer half-life (approximately 20–30 hours). For US-based researchers, sourcing this specific grade is essential for maintaining the validity of experimental data.

Why Choose Core Peptide Official?

Navigating the world of peptide procurement can be daunting. Core Peptide has solidified its reputation by providing a transparent, high-standard supply chain. When you visit corepeptideofficial.com, you aren’t just buying a vial; you are investing in scientific accuracy.

• Verified Purity: Every batch of IGF-1 LR3 undergoes stringent HPLC and MS analysis to ensure it meets the 100mcg specification exactly.

• USA-Based Logistics: We understand the urgency of research. Our domestic shipping ensures your materials arrive without the “red tape” or degradation risks associated with international transit.

• Optimal Stability: Our lyophilized (freeze-dried) powder is stabilized for maximum shelf-life, ensuring the receptor-binding affinity remains intact until reconstitution.

The Science: Mechanism of Action

IGF-1 LR3 functions as a highly effective mediator of growth hormone. In a controlled research environment, it stimulates cell proliferation and inhibits apoptosis (programmed cell death). Its primary value lies in its ability to facilitate nitrogen retention and protein synthesis at a cellular level.

Because it bypasses IGF-binding proteins (IGFBPs), the bioavailability of the 100mcg dose is significantly more predictable than other analogs. This makes it the ultimate tool for studying muscle cell hyperplasia and metabolic signaling pathways.

Quality Control: The Core Peptide Difference

The “Receptor Grade” label is often misused in the industry. At Core Peptide, we define it through a “Zero-Defect” policy. While cheaper, “media grade” alternatives exist, they often contain trifluoroacetic acid (TFA) salts or residual impurities that can skew your results or cause unintended cellular reactions.

By choosing the official website, corepeptideofficial.com, you ensure:

1. Sequence Authenticity: 83 amino acids in the precise recombinant sequence.

2. Endotoxin Testing: Minimal levels to ensure no interference with sensitive biological assays.

3. Vacuum Sealed Protection: Each 100mcg vial is sealed under sterile conditions to prevent oxidation.

Buying Guide for US Researchers

If you are wondering where to buy IGF-1 LR3 in the USA, look for domestic providers with accessible certificates of analysis (COA). Avoid “gray market” resellers who cannot verify the origin of their peptides. Core Peptide provides a secure, encrypted shopping experience designed for professional laboratories and independent researchers alike.
