IGF-1 LR3 + PEG-MGF (Multi-Vial Hypertrophy Kit)
Analytical Standards & Laboratory Handling
Verified laboratory protocols, reconstitution parameters, and handling guidelines.
Pharmacological Profile & Mechanism of Action
What it is: The IGF-1 LR3 + PEG-MGF Bundle is a dual-vial research kit consisting of 1 vial of Long R3 IGF-1 (1 mg) and 1 vial of PEG-MGF (2 mg), supplied for coordinated administration schedules.
How it works: PEG-MGF activates dormant muscle satellite stem cells and drives local myoblast proliferation, while IGF-1 LR3 subsequently drives satellite cell differentiation, protein synthesis, and amino acid uptake into mature myotubes.
Why researchers study it: Researched in muscle wasting, extreme athletic trauma recovery, and neuromuscular junction regeneration models.
