Evidence-based articles on testosterone, hormones, fitness, and longevity, so you can make informed decisions about your health.
Foods that kill zombie cells are not a single magic ingredient, but a pattern of whole foods rich in senolytic and senomorphic compounds that may help your body manage senescent cells. The science is promising, yet most “zombie cell” research uses high dose isolates, so your best move is to build an evidence based longevity ...
Soy foods contain isoflavones, but clinical studies have not found that soy or isoflavone intake changes testosterone or estrogen levels in men. This finding does not establish the effects of every food or environmental exposure. Symptoms or an abnormal estradiol result need assessment of the wider clinical context. Key takeaways Foods highest in phytoestrogens include ...
In the first few weeks of lifting, neural adaptations are primarily responsible for strength gains in beginning clients, often before large increases in muscle size are measurable.[1] [2] A novice can add weight to the bar quickly, and in one 21 week study, men without a strength training background improved maximal force more than five ...
Sex does not raise your long-term baseline testosterone. In controlled measurements, testosterone did not change around orgasm, while prolactin rose. The relationship runs in both directions. Testosterone supports libido and erectile function, and arousal and orgasm trigger brief neuroendocrine changes. Overall health often explains why higher testosterone and a better sex life tend to go ...
Sauna after a workout is usually the better choice. Brief sauna before a workout may help you feel warm, but longer heat exposure before training can impair performance and hydration. Most sauna research comes from regular traditional sauna use, often around 80 to 90°C, with sessions commonly lasting 5 to 20 minutes and sometimes longer ...
Most adult men spend about 10 to 25 percent of their total sleep time in deep sleep, which is roughly 45 to 120 minutes in an eight hour night. If you feel tired, foggy, or low drive despite “enough” hours, the missing piece is often sleep quality, including how much deep sleep you need and ...
Testosterone does not make your penis bigger after puberty. But if low testosterone is weakening your erections, restoring healthy levels can make your penis look and function bigger in the moment because erection quality improves. Key takeaways Testosterone drives penile growth in the womb and during puberty, largely through conversion to dihydrotestosterone, but it does ...
Creatine typically takes about 1 to 4 weeks to produce noticeable training benefits, depending on dosing and training style. Faster changes are possible if you use a short loading phase. Creatine has to build up inside muscle before it meaningfully boosts repeated high intensity efforts. Key takeaways Muscle creatine reaches a similar level after about ...
Ego lifting is using a weight that exceeds your current capacity for that exercise on that day, forcing you to cheat form or shorten range of motion to complete reps. It may feel like progress, but it shifts stress off the target muscle and onto joints and passive tissues. This can set you up for ...
Usually not. Average time from penetration to ejaculation is about 5 to 7 minutes, while lifelong premature ejaculation is typically orgasm within about 1 minute of penetration, and acquired premature ejaculation is a clinically significant drop from prior latency, often to about 3 minutes or less, along with poor control and distress. The hallmark issue ...
Usually no. For most men without diabetes, a CGM is not worth using long term, though a short structured trial can sometimes help with appetite or training questions. The key is knowing what a CGM can and cannot tell you, then using the data to make changes you can actually sustain. Key takeaways According to ...
Yes, you can eat high protein low fat fast food by prioritizing lean, grilled proteins and controlling the sides, sauces, and drinks that usually spike calories, fat, and sodium. The upside is big for men training for strength or body recomposition. You stay fuller, you recover better, and you avoid turning a quick meal into ...
