IGF-1 LR3
Long R3 IGF-1
People talk about it around training, for the growth signal itself. Have food nearby — low blood sugar is the practical risk. It is not a general healing peptide.

20–80 mcg
Schedule
Once daily, short cycle
Half-life
~20–30 hours (LR3)
How it is used
A workout-day peptide. Higher risk, not an everyday recovery pick.

4 weeks maximum is a common ceiling. Not a lifestyle peptide.
