Research backed education on training, nutrition, hormones, and supplementation, written to go deeper than a video can.
Your doctor looked at one number and said you were fine. That number was total testosterone, and depending on your SHBG level, it may have told almost nothing about what your body could actually use. To understand why, you need the full...
The fear around testosterone replacement therapy and heart attacks did not come from nowhere. It came from a wave of observational studies published in the early 2010s that showed men who started TRT had higher rates of cardiovascular e...
The fear started in 1941 with a researcher named Charles Huggins, who was studying men with advanced, metastatic prostate cancer and noticed something that seemed obvious at the time: when you removed the source of testosterone by castr...
Testosterone is made in the testes, regulated by signals from the brain, and constantly being pulled in different directions by other hormones in your body. One of those directions is conversion into estrogen, and another is suppression...
Your kidneys are constantly filtering your blood, and one of the things they filter out is a waste product called creatinine, which is what your body produces when it breaks down creatine. The rate at which your kidneys clear creatinine...
Cardarine gets discussed like the answer is obvious. Either it's a cancer bomb that no one should touch, or the rat studies are so overblown they tell us nothing useful about human risk. Neither of those positions holds up when you actu...
Your body already runs a blood vessel construction system, and BPC-157 turns up the volume on it. That system works through something called VEGF, which stands for vascular endothelial growth factor, and it functions essentially as a ch...
Your brain runs on about 20 percent of your body's total energy budget, and it produces that energy the same way your muscles do, which means the same system that powers a squat is also powering your ability to read this sentence and re...
Your body stores energy in a currency called ATP, which is essentially the molecule your muscles burn every time they contract, and the problem is you only have enough of it on hand for about two to three seconds of high-intensity effor...
The version most people choose is the one that requires fewer injections, and that logic makes sense on the surface but misses what the choice is actually about. CJC 1295 is something called a GHRH analog, which means it mimics the sign...
Your pituitary doesn't release growth hormone in a steady stream. It releases it in sharp, concentrated bursts, and those bursts are what make the whole system work. Understanding why that matters is the only way to understand what you'...
Your body is not just responding to a signal. It is counting how many times it has heard that signal, and when it decides it has heard enough, it starts ignoring it. That is the whole reason cycling exists as a concept, and understandin...
