AmplifyIGF-1 LR3
Long-acting growth factor for muscle and recovery.
About
What it is
IGF-1 LR3 is a modified version of insulin-like growth factor with a much longer half-life than natural IGF-1. It promotes muscle cell hyperplasia, accelerates recovery, and supports protein synthesis across all tissues.
How it works
IGF-1 LR3 has a modified amino acid sequence that prevents it from binding to IGF binding proteins, giving it a much longer half-life than natural IGF-1. It binds directly to IGF-1 receptors on muscle cells, promoting both hypertrophy and hyperplasia.
Benefits
Who it's for
What to expect
Week 1–2
Growth factor signaling activates. Recovery improves.
Week 4–6
Protein synthesis increases. Lean mass begins responding.
Week 8–12
Measurable muscle composition changes with consistent training.
Safety & tolerability
IGF-1 LR3 is a potent growth factor that requires careful dosing. Our care team monitors IGF-1 levels and adjusts protocols based on your response. Not appropriate for everyone — a thorough intake review is required.
How we compound
Single-source API
Every peptide is sourced from one vetted pharmaceutical-grade supplier — no blending from multiple sources.
Third-party tested
Independent labs verify purity, potency, sterility, and endotoxin levels before any batch is released.
Care team reviewed
A real person reviews your profile, your protocol, and your progress. Not an algorithm.
