The NHH-115 by Innovative Research of America is a 17β-Estradiol pellet system for controlled hormone delivery in scientific research. Each pellet delivers a precise dose of 0.72 mg over 60 days, using a Matrix-Driven Delivery (MDD) system for subcutaneous implantations. This design ensures stable hormone levels, eliminates the need for intermittent injections, and enhances reproducibility in research, making it ideal for endocrinology, oncology, and reproductive biology studies.
