Your body runs testosterone production through a multi-step signaling chain, and understanding the whole chain matters before you zoom in on any single part of it. The brain sends a signal down to the pituitary gland, which releases som...
Your thyroid makes testosterone possible. Not directly, not in the way most people think, but through a set of mechanisms that sit upstream of everything your testosterone system depends on, and if those mechanisms are broken, no amount...
Your mitochondria are running two separate repair systems right now, and most people trying to support them are only thinking about one at a time. The outer structure of a mitochondrion handles signaling and fusion, but the real work of...
Your appetite on retatrutide can drop so dramatically that people simply forget to eat for most of the day, and then they notice their hair is thinning, their energy is gone, and their thinking feels slow, and they assume the drug is do...
Your testosterone goes up, and then your estrogen goes up, and then your doctor prescribes a drug to suppress the estrogen, and now you have two hormones being managed instead of one. That is how most men end up on an aromatase inhibito...
The question sounds simple: how many sets per muscle group per week do you need to build muscle? But the answer reveals something about how your body handles training that most people never fully understand, and getting that wrong means...
Your doctor looks at a single number and tells you everything is fine, and meanwhile you can barely get through the day. The number is not wrong. It is just incomplete, and understanding why requires a quick look at how testosterone act...
The fear started with observational studies, and that matters because observational studies cannot randomly assign people to treatments, which means the men who ended up on TRT in those early studies were already different from the men ...
The story starts in 1941, when a researcher named Charles Huggins took men who had already been castrated and had advanced prostate cancer, gave them testosterone injections, and watched their cancer markers rise. He also showed that ca...
Tongkat ali is being marketed as a testosterone booster, and the question worth asking is whether that label is accurate, or whether it is selling you a version of the story that leaves out the most important part. To understand what to...
Your doctor measures kidney function by looking at a waste product in your blood called creatinine, which is what your body produces when it breaks down creatine, and your kidneys filter it out at a relatively steady rate so that the co...
Cardarine sits in a strange place in the performance world, somewhere between a compound people swear by for endurance and fat loss and a compound that a major pharmaceutical company quietly buried after seeing what it did in animals. T...
