$10.00
A hormone structurally similar to insulin that mediates many of the tissue-building effects of growth hormone.
The FDA-approved form (mecasermin) treats severe primary IGF-1 deficiency in children; the ‘LR3’ variant is popular off-label in bodybuilding for its longer half-life and reported muscle-building effects.
Promotes cell growth and muscle protein synthesis; also plays a role in normal growth and metabolism throughout the body.
Mecasermin is FDA-approved for a narrow pediatric indication. IGF-1 LR3 sold for bodybuilding/research use is unapproved, unregulated, and carries theoretical long-term risks (including concerns about abnormal tissue growth) that are not well studied in humans.
