About Myostatin
- What it is
- GDF-8, known as myostatin, is a naturally occurring protein of the transforming growth factor beta superfamily produced mainly in skeletal muscle. It normally limits muscle growth so muscles do not become too large, acting as a negative regulator. Loss-of-function changes in animals and rare humans cause increased muscle mass. Because it restrains growth, research targets blocking it rather than administering it.
- How it works
- Myostatin signals through activin type II receptors and SMAD proteins to suppress skeletal muscle cell growth and differentiation.
- Researched for
- Muscle growth regulation; myostatin inhibition research; muscular dystrophy research; livestock genetics
- Half-life
- Not established in humans
- Familiarity
- Advanced
- Research evidence
- Animal studies only
- Regulatory status
- Phase 3
- Key risk
- None documented; this is the endogenous protein that limits muscle growth and is not administered as a therapy.
Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
