Injectable Hormones

Meaning

Pharmaceutical preparations of hormones, typically steroid hormones like testosterone or estrogen, or peptide hormones like human chorionic gonadotropin (hCG), formulated for subcutaneous or intramuscular administration. This route of delivery is favored in clinical practice because it bypasses first-pass metabolism in the liver, leading to higher bioavailability and more predictable serum concentrations compared to oral forms. Injectable preparations are a cornerstone of many hormone replacement and optimization therapies.
