Vegans Took Creatine for 4 Weeks: Jumps Rose, Sprints Didn't
Vegans eat almost no dietary creatine, so does supplementing hit harder? A new randomized, triple-blind human trial gave 20 active vegans 0.1 g/kg/day of creatine monohydrate for four weeks. Jump performance improved, and so did some body composition measures, but sprint, handgrip and mid-thigh pull results didn't budge. Body water climbed 1.4 kg, and the study couldn't compare vegans with meat-eaters. Here's what the numbers show, what they don't, and who might want to try it.
Shilajit Tested: Can 'Mountain Tar' Really Raise Testosterone?
Shilajit, the Himalayan "mountain tar" sold as a natural testosterone booster, was put through a randomized, double-blind, placebo-controlled trial. In men aged 45 to 55, 250 mg of purified Shilajit twice daily for 90 days significantly raised total testosterone, free testosterone and DHEAS versus placebo, while LH and FSH stayed stable. The study is promising but modest, limited to middle-aged men, and reports hormone levels rather than gym performance. Here's what the research shows, what it doesn't, and why purity and heavy-metal testing matter when buying.
