Peptide Reference
IGF-1 DES
Insulin-Like Growth Factor-1 Des(1-3)
A truncated form of IGF-1 that is significantly more potent for muscle growth due to reduced binding to IGF-binding proteins.
Status
research
Category
muscle
Typical cost
$100-200/vial (1mg)
Mechanism
Lacks the N-terminal tripeptide which allows it to evade IGF-binding proteins, resulting in higher free concentrations and more potent anabolic effects on muscle tissue.
Potential benefits
- Extreme muscle growth
- Site-specific growth
- Rapid recovery
- More potent than IGF-1 LR3
Reported side effects
- Hypoglycemia risk
- Organ growth
- Acromegaly features
- Banned in sports
- Cancer concerns
Common dosing references
subcutaneous or intramuscular
20-50mcg · 1-2x daily
