IGF-1 is basically a polypeptide hormone that has the same some of the same molecular properties as insulin. IGF dose actually stand for insulin-like growth factor. IGF-1 is mainly responsible for long bone growth in children and it also affects muscle growth and repair of adults. Long R3 IGF-1 is a more potent version of IGF-1. It’s chemically altered i like to think “enhanced” to prevent deactivation by IGF-1 binding proteins in the bloodstream. This results in a longer half-life of 20-30 hours instead of 20 min… So that means a far more effective version than the short chain we we re perhaps more familiar with.

How to use : Dosages are as follows for IGF-1 LR3: No more than approximately 40 – 50mcg per day should be used by men, and no more than 20mcg per day for females. Because of its long active half-life in the body, the LR3 variant should only be administered once and no more than twice per day. On training/workout days, the IGF-1 dosage should be administered either just before the workout or just after the workout. It is up to the user’s preference, as either before or after is perfectly fine (as is pre-workout only, or post-workout only). If administered twice per day, the full daily dosage can be split in half between the two (e.g. 20mcg pre-workout, and 20mcg post-workout for a total of 40mcg per day). On non-training days, it can be administered at any time of the day.

Either form of IGF-1 can be administered intramuscularly, or subcutaneously. Use of either form should not exceed cycle lengths of 30 days’ total before taking a minimum of 2 weeks off, though longer breaks than 2 weeks between IGF-1 cycles are recommended. This is not only because of the risk of health effects in the long term, but also to ensure IGF-1 receptors return to proper working order following a cycle.
