IGF-1 DES Benefits
- ✓Highly potent localized muscle growth, enhanced protein synthesis, satellite cell proliferation, does not bind to IGFBPs, rapid onset
Histatin-5 Benefits
- ✓anti-Candida activity
- ✓biofilm suppression
- ✓mucosal wound support
- ✓oral innate immunity
IGF-1 DES Dosing
50-150 mcg per injection site bilaterally post-workout. 4-6 week cycles due to potency. Multiple daily injections in research.
Histatin-5 Dosing
topical rinse or gel|short contact exposure|repeat applications in research protocols
IGF-1 DES Side Effects
- ⚠Hypoglycemia (dose-dependent), localized swelling, shorter duration limits systemic exposure compared to IGF-1 LR3.
Histatin-5 Side Effects
- ⚠local irritation
- ⚠proteolytic instability
- ⚠dose-dependent cytotoxicity in vitro
Research Overview
IGF-1 DES
Missing first three amino acids (Gly-Pro-Glu) eliminates IGFBP binding, resulting in 100% bioavailable IGF-1R stimulation. Activates PI3K/Akt/mTOR for protein synthesis and satellite cell proliferation.
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
