Modified IGF-1 analog with an extended N-terminal tail and Arg-for-Glu substitution at position 3 — giving it a far longer half-life and much lower binding to IGFBPs than native IGF-1.
Pre-filled with standard IGF-1 LR3 values. Adjust as needed.
Standard: 20–50mcg daily systemic. Site-specific injection near target muscle common pre/post workout. Cycles typically 4–6 weeks. Higher doses (50–100mcg) used by advanced users only.
Blood markers to track
Note: Not a peptide in the classical sense — recombinant protein variant. Standard IGF-1 assay will NOT detect LR3 (different epitope) and may show suppressed endogenous IGF-1 due to feedback. Monitor glucose — can cause hypoglycemia.
Log every IGF-1 LR3 injection alongside your IGF-1 (may read suppressed — LR3 does not cross-react on standard assay) and Fasting glucose readings. Compare draws over time in your free dashboard — so the next change you make is based on your numbers, not a guess.
