Anabolic Growth Factor
IGF-LR3
Insulin-like Growth Factor Long R3
Starting at $300
IGF-LR3 (Insulin-like Growth Factor-1 Long R3) is a modified form of IGF-1 with significantly extended half-life and potency. It directly stimulates muscle cell growth, fat oxidation, and tissue repair — acting downstream of GH to produce anabolic and regenerative effects with greater duration than native IGF-1.
Direct anabolic signaling.
Unlike GH secretagogues that stimulate the pituitary, IGF-LR3 acts directly on IGF-1 receptors throughout the body — bypassing the GH-liver axis for immediate anabolic action.
Direct Anabolic
IGF-1 Receptor Activation
Binds directly to IGF-1 receptors on muscle cells, triggering protein synthesis, hyperplasia (new cell creation), and hypertrophy (cell size increase) — the fundamental mechanisms of muscle growth.
Result: Direct stimulation of muscle protein synthesis and growth
Long R3 Modification
Extended Half-Life
The 'Long R3' modification reduces binding to IGF binding proteins (IGFBPs), extending the active half-life from minutes (native IGF-1) to hours — producing sustained anabolic signaling throughout the day.
Result: Prolonged anabolic signaling from a single daily injection
Lipolysis
Fat Oxidation
IGF-LR3 activates adipocyte lipolysis — the breakdown of stored fat for fuel — while simultaneously building lean tissue, producing potent body recomposition effects.
Result: Simultaneous muscle gain and fat loss (body recomposition)
Clinical Benefits
What you can expect from IGF-LR3 therapy
Muscle growth & hyperplasia
Directly stimulates new muscle cell creation and growth — one of the few peptides that promotes muscle hyperplasia, not just hypertrophy.
Body recomposition
Simultaneous muscle gain and fat loss — particularly effective during caloric restriction phases.
Accelerated recovery
Enhanced tissue repair and reduced recovery time between training sessions.
Injury healing
Promotes repair of muscle, connective tissue, and bone through direct IGF-1 receptor stimulation.
Neuroprotection
IGF-1 receptors in the brain mediate neuroprotective effects — potentially beneficial for cognitive function.
Anti-aging
IGF-1 levels decline with age; restoration produces comprehensive anti-aging effects across multiple tissue types.
The Process
What to expect & when
Realistic timeline for IGF-LR3 results
Weeks 1–2
Recovery Improvement
Faster recovery between training sessions as IGF-1 receptor activation accelerates tissue repair.
Weeks 2–4
Body Composition Shift
Visible changes in muscle fullness and early fat reduction as anabolic and lipolytic pathways activate.
Weeks 4–8
Structural Changes
Measurable increases in lean mass. Fat reduction continues. Strength gains accelerate.
2–4 Months
Peak Results
Maximum body recomposition achieved. Long-term courses may produce permanent muscle fiber hyperplasia.
