IGF-LR3
Fator de crescimento semelhante à insulina de ação prolongada — crescimento muscular e recuperação
Visão Geral
IGF-LR3 é uma versão modificada do fator de crescimento semelhante à insulina 1 (IGF-1) com meia-vida prolongada para efeitos sustentados de construção muscular.
Key Information
Mecanismo
Liga-se aos receptores de IGF-1 para promover a síntese de proteínas musculares, a ativação de células satélites e a hipertrofia muscular. A modificação LR3 estende a meia-vida para ~20 horas.
Benefits
- Hipertrofia muscular
- Recuperação aprimorada
- Ativação de células satélites
- Meia-vida prolongada (LR3)
Side Effects
- Risco de hipoglicemia
- Preocupações com crescimento de órgãos em doses elevadas
- Dor no local da injeção
Contraindications
- Active cancer
- Diabetes (hypoglycemia risk)
Evidence Summary

IGF-LR3 is the most potent muscle-building peptide I've used. Hypertrophy is noticeable within 2 weeks. Recovery between workouts is dramatically faster. The extended half-life of LR3 makes it superior to regular IGF-1. Handle with respect - this is powerful.
IGF-LR3 delivers on muscle growth. Pump is incredible, recovery is fast. The LR3 variant lasts 20-30 hours which is much better than DES. Need to be careful with blood sugar - can cause hypoglycemia. Not for beginners.
