I expect your doctor to tell you you’re numbers are within range and normal, only in reality there not even close to normal testosterone for a young 25 year old, right now a 72 year old president has higher levels.
Younger men typically have higher testosterone than older men, typically men your age on average are scoring in the 800 ranges and high normal or higher Free T.
Expect endocrinologists and urologists to be clueless in endocrine disorders related to testosterone, most would say you’re too young for TRT and would brush you off and just feed you you’re fine and in range when really they want you to leave becoming someone else’s problem.
Sick care doctors, the medical community believe TRT is taboo and ethically wrong, most doctors upon seeing your labs would like nothing more for you to just leave their office immediately.
A lot of men who come here also have undiagnosed hypothyroidism and are told by their doctors their thyroid numbers are in range and normal, TSH reference ranges are not normal and doctors are operating on old outdated information, feeling cold and rapid weight gain are common symptoms of hypothyroidism.
Private doctors are more up to date and where you should be looking for treatment, anti-aging and sports medicine.
Do you have more labs such as LH and FSH?
