How well researched is this?
Very Early Research Status
Published preclinical research demonstrates significantly higher tissue-level potency than IGF-1 LR3. No human clinical trials have been conducted.
Legal status
Expected to return to legal compounding status in 2026, meaning licensed doctors can prescribe it and regulated pharmacies can prepare it.
2026 reclassification status updates coming soon.
Purity

HPLC Purity Tested
Always require a Certificate of Analysis (CoA) from a US-based compounding pharmacy.
