IGF-1 DES
peptide · headlineResearch use onlyBinds to IGF-1 receptors with higher affinity than native IGF-1
Summary
IGF-1 DES is a truncated, highly active form of IGF-1 with enhanced potency at muscle sites due to its low affinity for IGFBPs. It is studied for its potent anabolic signaling in muscle cells, especially during acute injury or mechanical overload in preclinical models.
How it works
- Binds to IGF-1 receptors with higher affinity than native IGF-1
- Avoids IGF-binding proteins for greater local effect
- Stimulates protein synthesis and cell proliferation in muscle
Dosing
- unit: mcglow dose: 10frequency: Dailyhigh dose: 100standard dose: 50administration route: Subcutaneous (SQ)
Cycling
- 1–2x daily post-workout or site-specific application. Recommended cycle: 4–6 weeks on, followed by equal off-time to avoid IGF-1 receptor downregulation.
Side effects
common: ["Hypoglycemia","Injection site swelling or sensitivity"]
warnings: ["May induce insulin resistance in long-term use","Avoid in individuals with cancer or at high cancer risk"]
long term: ["Potential changes in insulin signaling pathways and glucose homeostasis"]
Chemistry & PK
sequence: Thr-Lys-Pro-Ser-Ser-Thr-Gln-Cys-Asn-Ser-Glu-Gln-Leu-Glu-R
half life: 20–30 minutes
degradation: Rapidly degraded unless stabilized in cold-chain or modified carriers
molecular weight: 7491.4
molecular formula: C331H513N91O97S7
tissue specificity: Acts at muscle repair sites and insulin-sensitive tissue
