Medically reviewed articles on testosterone, hormones, fitness, and longevity, so you can make informed decisions about your health.
Semen retention is deliberately avoiding ejaculation for a period of time. Research suggests it does not produce a sustained testosterone boost. According to a 2001 study in World Journal of Urology, there was a modest rise around day 7 of abstinence that drifted back toward baseline despite continued retention. Here’s what the evidence says about ...
Testosterone itself isn’t the direct cause of male pattern hair loss; the issue arises when 5‑alpha reductase converts it into DHT, which miniaturizes genetically androgen‑sensitive scalp follicles even when total testosterone is normal. With androgenetic alopecia affecting roughly 30% to 50% of men by age 50, the real question is whether your follicles are “wired” ...
Converse-style zero-drop, incompressible flat soles can improve center-of-pressure stability and reduce energy loss from sole compression in deadlifts, but for squats they remove the 0.75 to 1 inch heel lift that helps ankle dorsiflexion. If mobility is restricted, that can increase knee and lumbar torque. Here is how to know when flat shoes are the ...
For male runners, the essential biomarker list starts with ferritin and iron studies, vitamin D, glucose, and a hormone panel that includes total testosterone, free testosterone, LH, and FSH, because a testosterone value below 350 ng/dL total or 100 pg/mL free only matters when symptoms persist and the pituitary signals are checked too. Magnesium and ...
As of May 2026, BPC-157 has 0 FDA approved drugs for human use in the United States. That means the common searches “bpc-157 fda approval status 2026,” “bpc-157 legal status us 2026,” and “bpc-157 fda status 2026 compounding ban” all point to the same practical answer: online availability does not equal FDA approval, routine lawful ...
You get rid of food noise by lowering the biologic drivers that keep appetite turned up. Meals built around 25 to 30 g of protein, fewer ultra processed cues, and 7 to 9 hours of sleep can all help quiet constant food thoughts. For eligible men, obesity medicines are linked to about 14.9% to 20.9% ...
Yes. Recreational runners generally live longer than non-runners, and even 5 to 10 minutes a day at an easy pace is associated with lower mortality and longer lifespan. The sweet spot for longevity appears to be moderate weekly volume (around 2 to 3 hours), not marathon-level mileage. Here is how it works and how to ...
“Testosterone killing foods” are foods that, when eaten often as part of an ultra processed Western style diet, are linked to lower testosterone in men through inflammation, insulin disruption, and weight gain. The good news is that you do not need a perfect diet. You need a few high impact swaps and the right lab ...
The Cloud X 3 functions as a true hybrid only for moderate lifting and short runs (about 1 to 4 miles) by pairing firmer, less-compressible CloudTec foam with a Speedboard to improve force transfer while still attenuating running impacts that can exceed 2.5 times body weight. This evidence-based review breaks down where that stability and ...
Volume eating is a nutrition strategy that emphasizes high volume, low calorie foods so you feel full while naturally eating fewer calories. Done right, it can make fat loss feel less like willpower and more like smart meal design. “Volume eating works best when you treat it as a way to add smart volume, not ...
Most cases of dry, flaky, or itchy penile skin are irritant contact dermatitis from barrier breakdown in the penis’ thin stratum corneum (often triggered by friction, sweat, soaps, detergents, or condoms), not an STI. Here’s how to tell simple irritation from eczema, psoriasis, yeast, or balanitis. Here is what actually helps the skin heal. “Most ...
A hot flush in males is most often triggered by a meaningful drop in testosterone that disrupts the brain’s temperature control. The good news is that male hot flashes are common, measurable, and usually treatable once you identify the driver. “When a guy tells me he’s getting sudden heat waves and drenching sweat, I think ...
