IGF-1 DES

Also known as: IGF-1 DES(1-3), Des(1-3)IGF-1, DES IGF

The Targeted Muscle Growth Peptide

Truncated IGF-1 variant that's 10x more potent than regular IGF-1. Popular for localized muscle growth when injected directly into target muscles.

How It Works

Simple Explanation

Supercharged version of IGF-1 that promotes muscle cell growth and division, especially effective when injected locally.

Technical Details

Des(1-3)IGF-1 lacks the first 3 amino acids of IGF-1, reducing binding protein affinity and increasing bioavailability. Activates IGF-1R with ~10x potency of intact IGF-1.

Pharmacokinetics & Storage

Half-Life

~20-30 minutes

Duration in circulation

Storage Requirements

Before use: Store lyophilized at -4°F to 39°F (-20°C to 4°C)

After reconstitution: Use within 24-48 hours (very unstable)

Extremely fragile. Reconstitute only what you'll use. Acetic acid may improve stability.

Frequently Asked Questions

Why inject into the muscle I trained?

IGF-1 DES has localized effects. Injecting into the trained muscle maximizes growth in that specific area.

What's hyperplasia?

Creation of new muscle cells, as opposed to hypertrophy (enlarging existing cells). IGF-1 DES may promote both.

Why is it so unstable?

The truncated structure that makes it potent also makes it degrade quickly. Always use fresh and store properly.
