How to Use IGF-1 LR3
Complete guide to IGF-1 LR3 dosing, administration, timing, and protocol recommendations.
Quick Overview
IGF-1 LR3 is a modified version of insulin-like growth factor 1, engineered to last far longer in the body than the natural hormone. It is popular in physique circles and it is worth being blunt about the evidence: there are effectively no human clinical trials of this specific analog. Everything below the mechanism section is preclinical work, laboratory use, or community reporting.
Dosing Guidelines
Common Dose
20-50 mcg daily
Frequency
Once daily
Dose Range
20-50 mcg daily (community reported)
Note: There is no clinical dosing standard because there are no clinical trials. Hypoglycemia is the risk that most often requires medical attention with this compound, and community reports consistently describe it coming on quickly.
Administration Method
Subcutaneous injection. Because of the hypoglycemia risk, timing relative to carbohydrate intake is the main practical consideration reported.
Best Time to Take
With or near a carbohydrate-containing meal
The dominant acute risk is hypoglycemia. Community protocols consistently pair dosing with food for that reason.
Protocol Duration
Community cycles are typically reported as 4-6 weeks, on the reasoning that receptor downregulation follows longer use
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Hypoglycemia, the most immediate and serious risk
- •Hunger and lightheadedness as early hypoglycemia signs
- •Injection site reactions and localized tissue growth
- •Joint pain
- •Theoretical promotion of existing tumor growth with sustained elevated IGF-1 signalling
