IGF1-LR3

IGF1-LR3 is Pharmaqo Labs' version of Long R3 Insulin-like Growth Factor 1, a peptide analogue of IGF-1. IGF-1 carries out many of the muscle-building effects of growth hormone. It binds to IGF-1 receptors and increases protein synthesis and nutrient uptake, which supports muscle growth and faster recovery. The LR3 modification keeps it active far longer than natural IGF-1.

It comes as a freeze-dried powder that you reconstitute with water and inject, usually once a day subcutaneously or intramuscularly. Cycles are typically short, around 4 to 6 weeks. Many users time the dose around training or a carbohydrate meal to reduce the drop in blood sugar. These are commonly reported patterns for information only, not medical advice.

The most common issues are low blood sugar (hypoglycaemia), joint pain, some water retention and tingling or numbness in the hands. Keeping fast-acting carbohydrates on hand helps if blood sugar drops. It is a peptide rather than a testosterone-based steroid, so on its own it does not need a PCT, though any steroid base you stack it with will.

IGF1-DES acts fast and clears quickly, so it is used for a localised, short pulse. IGF1-LR3 has a much longer half-life, reported around 20 to 30 hours, so a single daily dose stays active across the day and needs fewer injections. That makes LR3 the more convenient choice for general daily use.

The powder is stable before it is mixed. Once you reconstitute it with water, keep the vial in the refrigerator to protect its potency. Avoid heat and shaking the solution too hard.
