A bright, modern editorial flat-lay photographed from above on a soft off-white stone surface. At the center sits a matte ceramic scoop heaped with fine white creatine powder, with a loose dusting of powder fanning out across the surface. Beside it is a minimalist frosted-glass jar with a plain label and a brushed-steel shaker bottle lying on its side. To the left, a wooden comb and a small folded strip of graph paper with a single hand-drawn upward curve in muted terracotta ink, suggesting a data spike without any text. A few loose strands of dark brown hair curve elegantly across the stone near the comb. To the right, a clean glass beaker filled with water and a sprig of green rosemary, and an open notebook with blank pages and a sleek pen. The palette is warm neutrals: cream, sand, soft sage green, and a single accent of terracotta orange. Natural window light falls from the upper left, casting long, gentle shadows and a subtle diffused glow. The composition leaves generous negative space on the right third for title overlay. Shallow depth of field with crisp focus on the powder scoop, a premium health-and-science magazine look, minimalist, calm, and trendy, with fine grain and soft contrast. Landscape 16:9 framing.

肌酸与脱发：血清DHT升高56%背后的真相

BY DR. GYMBRO · 2026年10月19日

2009年的一项研究显示，连续7天每天摄入25克肌酸后，血清二氢睾酮（DHT）上升了56%，随后在每日5克的维持剂量下仍比基线高约40%，而睾酮水平并未改变。因为DHT与男性型脱发密切相关，这一发现让“肌酸会导致脱发”成为热议话题。但该研究仅涉及20名橄榄球运动员，持续时间只有三周，且从未测量过头发情况。后续研究也未一致复制出DHT升高的结果。本文将澄清真实结论、受影响的人群以及如何在担心脱发的情况下合理使用肌酸。
