Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.
| Attribute | IGF-1 LR3 | MGF |
|---|---|---|
| Category | Growth Factor | Growth Factor |
| Evidence Rating | D — Preclinical | D — Preclinical |
| Clinical Status | No clinical trials for therapeutic use. Research compound only. | Preclinical only. No human clinical trials. |
| Mechanism | IGF-1 LR3 binds to IGF-1 receptors on target cells with high affinity, initiating tyrosine kinase signaling that activates the PI3K/Akt/mTOR pathway, increasing protein synthesis, glucose uptake, and cellular survival while inhibiting muscle protein breakdown (anti-catabolic). Its low affinity for I... | MGF is expressed as part of the IGF-1 gene through alternative splicing in response to mechanical overload or tissue damage. The E-domain peptide (distinct from the mature IGF-1 peptide) activates satellite cells — muscle stem cells that donate nuclei to growing or repairing muscle fibers. It upregu... |
