IGF-1 LR3 vs Adamax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- IGF-1 LR3 is a synthetic analog of Insulin-like Growth Factor-1 with an extended half-life. It is one of the most potent anabolic peptides available, directly stimulating muscle cell hyperplasia and hypertrophy, and is the downstream mediator of many of GH's anabolic effects.
- Adamax is a synthetic neuropeptide related to brain-derived neurotrophic factor (BDNF) signaling pathways. It is explored for cognitive enhancement, neuroprotection, and mood support, with proposed mechanisms involving TrkB receptor activation and enhancement of neuroplasticity similar to endogenous BDNF.
- Half-Life
- 20–30 hours
- Estimated 1-3 hours (short; peptide degradation)
- Admin Route
- SubQ, IM
- Subcutaneous, Intranasal (research)
