Understanding the “1000mcg” Label

The 1000mcg designation refers to the total peptide content supplied in a vial. This label helps with cataloging, inventory management, and standardization across research suppliers.

Importantly, it does not represent guidance for use. Instead, it serves as a reference for product quantity within laboratory or research distribution.

How IGF 1 LR3 Differs From Native IGF-1

Understanding the distinction between IGF 1 LR3 and natural IGF-1 clarifies why researchers choose one over the other.

Native IGF-1

• Shorter half-life

• Rapid binding to IGF-binding proteins

• Limited stability in circulation

IGF 1 LR3

• Extended half-life in research models

• Reduced binding to IGF-binding proteins

• Greater stability for experimental observation

Therefore, IGF 1 LR3 allows researchers to observe IGF-related signaling over a longer period.

IGF-1 LR3 PEPTIDE OVERVIEW

Currently there are 3 versions of injectable IGF 1 LR3 1000mcg peptides on the market:

• IGF 1 LR3 1000mcg (or DES IGF-1) with a half-life of just 30 minutes;
• IGF-1 LR3 modification — with an effective half-life of 20-30 hours;
• Base IGF-1 —weaker and quickly dissolved by your body’s natural filtering.

IGF-1 in LR3 modification (meaning Long R3, with extra 13 amino acids and arginine at the 3rd position) by Apoxar is an amino acid analog to a natural IGF-1. It’s more powerful and stays active in your body for a longer period.

LR3 is the most cost-effective IGF-1 version available.

IGF-1 Benefits:

• Significant muscle growth;
• Endurance and strength boost;
• Not synthetic, a natural compound;
• No water retention, no suppression;
• Pharm-grade quality;
• 3rd party lab-tested, independent check.
