How Defy Medical Compares to a Standard Endocrinology Practice A board-certified endocrinologist at a hospital system will typically follow the same diagnostic threshold but is far less likely to prescribe testosterone cypionate via self-administered subcutaneous injection, prescribe human chorionic gonadotropin (hCG) for testicular preservation, or add peptides to a protocol

Its defined molecular structure and sequence integrity make it suitable for laboratory workflows requiring reproducibility, traceability, and controlled experimental conditions

This makes it safer for longer-term use and eliminates concerns about developing insulin resistance
