Overview
This page focuses on how to think about basic dose and exposure concepts in an abstract way for IGF-1 LR3 and similar peptides. It does not provide dosing instructions or protocols.
Key themes in dosing concepts
- Understanding vial amount, dilution volume, and resulting concentration.
- Relating concentration to an abstract "unit" or hypothetical dose.
- Recognizing that pharmacokinetics (absorption, distribution, metabolism, elimination) influence exposure beyond simple vial math.
Context and caveats
Any concrete dosing decisions for IGF-1 LR3 must be grounded in product labelling (where it exists), formal clinical guidance, and individualized medical judgment. Educational tools such as calculators and half-life plotters are best treated as aids for understanding, not as dosing engines.
Sport & Anti-Doping Warning
IGF-1 LR3 is a long-acting insulin-like growth factor analogue noted by anti-doping experts as a potent, hard-to-detect performance enhancer; it is covered under the WADA category for peptide hormones and growth factors.

Even without many public positive tests, laboratories treat IGF-1 LR3 as a high-priority target substance in the GH–IGF axis.
