Very small draw (2.0 units) — difficult to measure accurately. Consider using less BAC water for a more concentrated solution.

Summary: Add 1mL BAC water to your 1mg vial. Draw to 2.0 units on a U-100 syringe for a 20mcg dose. This vial will last 50 doses.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Note: Long-acting IGF-1 analog (LR3 = Long R3). Much more potent than regular IGF-1. Very low doses — use an insulin syringe for accuracy. Cycle 4-6 weeks on, 4 weeks off. Monitor blood sugar.

About IGF-1 LR3

IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of IGF-1 with a much longer half-life and greater potency. IGF-1 is the downstream effector of growth hormone — GH tells the liver to produce IGF-1, which then drives muscle growth (including hyperplasia: the creation of new muscle cells), recovery, and cellular regeneration. The LR3 modification makes it 2-3x more potent with a half-life of 20-30 hours vs 15 minutes for regular IGF-1.
