Muscle & Performance
IGF-1 LR3
Feed the muscle directly.
Skip the middleman. IGF-1 LR3 is a long-acting version of the growth factor your body makes downstream of growth hormone — the one that actually tells muscle cells to grow and repair. Built to stay active longer than natural IGF-1. A 1 mg pen, dosed by the dial, logged by the app.

Research emerging
Human data still coming in
- What the science shows
- IGF-1 LR3 is engineered to resist the binding proteins that normally switch IGF-1 off, so it stays active in the body far longer. Early research — human outcome trials are the next step.
- Who was studied
- Early-stage research on an engineered IGF-1; human outcome trials still ahead.
- Good to know
- It can drop your blood sugar — dose around a meal and keep carbs handy. Talk to your doctor before starting if you have diabetes or any history of tumors, since IGF-1 drives cell growth. Skip it if you're pregnant.
