Description
Lypholized powder requiring reconstitution.
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic analog of the naturally occurring growth factor IGF-1. Engineered with structural modifications that extend its half-life from a few minutes to 20–30 hours and prevent binding to neutralizing proteins, it is highly potent in research and performance contexts.
How It Works & Key Effects
IGF-1 LR3 bypasses intermediate signaling steps, stimulating cellular pathways (like PI3K/Akt and MAPK) directly at the receptor level.
-
- Hyperplasia: Unlike regular anabolic agents that simply enlarge existing muscle cells, IGF-1 LR3 is heavily utilized in bodybuilding communities for its potential to stimulate the creation of new muscle cells (hyperplasia).
- Nutrient Partitioning: It helps direct carbohydrates and amino acids into muscle tissue rather than fat storage.
- Enhanced Recovery: It significantly shortens recovery times between intense training sessions by facilitating tissue repair
