IGF-1 LR3 vs Cardiogen

Side-by-side comparison of key properties, dosing, and research.

Anabolic & IGF
IGF-1 LR3
Anti-Aging & Longevity
Cardiogen
Summary
IGF-1 LR3 is a synthetic analog of Insulin-like Growth Factor-1 with an extended half-life. It is one of the most potent anabolic peptides available, directly stimulating muscle cell hyperplasia and hypertrophy, and is the downstream mediator of many of GH's anabolic effects.
Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.

Key Benefits
  • Direct muscle hypertrophy via IGF-1R stimulation
  • Muscle hyperplasia (new fiber formation) — unique among peptides
  • Rapid gains in lean muscle mass
  • Accelerated recovery from training and injury
  • Increased nutrient uptake by muscle cells
  • Fat oxidation enhancement
  • Bone density improvement
  • Cartilage and connective tissue repair
  • Cardioprotective effects on myocardial tissue
  • Normalization of cardiomyocyte protein synthesis
  • May improve cardiac rhythm and conduction
  • Support for recovery from ischemic cardiac events
  • Anti-aging effects on heart tissue
  • Potential reduction in cardiac fibrosis
  • Often combined with Epithalon for comprehensive cardiovascular longevity support
Side Effects
  • Hypoglycemia (significant risk — insulin-like activity)
  • Acromegaly-like effects with excessive long-term use
  • Jaw and hand swelling
  • Organ hypertrophy with extreme doses
  • +2 more
  • Generally well tolerated in available research
  • Mild injection site reactions
  • No significant adverse cardiovascular events reported at standard doses
