IGF-1 LR3 is a modified IGF-1 with 3x longer half-life (20–30 hours) due to reduced binding protein affinity. IGF-1 is the primary anabolic mediator of GH effects — driving muscle protein synthesis, satellite cell activation, and potentially true muscle hyperplasia (new cell creation). One of the most potent muscle-building peptides available. Conservative dosing and short cycles (4–6 weeks maximum) are essential due to its potency. Always have carbohydrates available — hypoglycemia risk is real.

Frequently Asked Questions
Q: IGF-1 LR3 dose?
A: 20–100 mcg daily post-workout. Start at 20–40 mcg. Maximum 6-week cycle with equal break.
Q: When to inject?
A: Post-workout in target muscle for local effect, or subcutaneous for systemic. Always have carbs available.
Q: Is it dangerous?
A: Hypoglycemia risk is real. Possible organ growth at high chronic doses. Avoid with cancer history.
