IGF-1 LR3 Dosage: Research Protocol Guide
IGF-1 LR3 is a modified version of insulin-like growth factor 1 with a longer half-life. It is a potent research peptide, and dosing is measured carefully. This guide collects the reported ranges into a chart. Figures are research-reported, not dosing advice.
How IGF-1 LR3 dosing is expressed
Doses are given in micrograms and are notably smaller than many other peptides because IGF-1 LR3 is highly active. Its extended half-life, reported in the range of a full day, means it stays present far longer than native IGF-1.
| Context | Reported daily range | Frequency |
|---|---|---|
| Lower research range | 20 to 40 mcg | Once daily |
| Common research range | 40 to 80 mcg | Once daily |
| Cycle length | often 4 weeks | then a break |
Because the peptide is potent, small measuring errors matter more than usual. Use the dosage calculator to convert your target micrograms into exact syringe units for your vial and water volume.
Timing considerations
Some protocols place the dose post-training or in the morning. The full method notes and cautions are on the IGF-1 LR3 protocol page. Because IGF-1 affects blood sugar pathways, protocols treat it with extra care.
Why accuracy dominates
With a potent peptide, consistency of measurement is the single most important research habit. A dosing chart is a starting reference, but the real work is drawing the same accurate amount each time.
