How it Works

Nature’s Sunshine IGF-1 (insulin-like growth factor 1) is a metabolite of HGH, human growth hormone. IGF-1 may promote bone and tissue development. Nature’s Sunshine IGF-1 may also help recovery from training injury or fatigue. Each bottle contains at least 2,500 nanograms of IGF-1 and other insulin-like growth factors.


Recommended Use

Spray twice under the tongue, 3 times daily. Hold for 20 seconds before swallowing for best results.
