Description
IGF-1 LR3 1mg, for research use only, is a synthetic version of insulin-like growth factor 1 (IGF-1) with an extended half-life due to the substitution of arginine for glutamic acid at the third position. This modification enhances its stability and biological activity, making it ideal for scientific studies. IGF-1 LR3 is commonly used in research to investigate cellular growth, muscle development, and recovery processes. It is supplied as a lyophilized powder and requires reconstitution with bacteriostatic water before experimental use. Intended strictly for in vitro research or laboratory studies; not for human use. Proper handling and safety procedures are essential.

I’ve combined this with my usual peptide stack, and the results are insane. I’m gaining lean muscle mass without excessive water retention. Definitely worth it!

I noticed better pumps and recovery, but it took a couple of weeks to really feel the effects. Patience is key, but it does work well!
