- This table tells a story that numbers alone cannot. TRT carries heavier side effects because it is a heavier intervention. It replaces a system rather than supporting one. For men with genuine hypogonadism, these risks are justified because the alternative, living with severely low testosterone, carries its own serious health consequences including metabolic syndrome, osteoporosis, depression, and cardiovascular disease. But for men with mild to moderate decline, the risk-benefit calculation shifts significantly toward peptides.
- Understanding peptide therapy cost is also important in this comparison, as the financial commitment differs substantially between the two approaches.
