**Approach: Lab in action. Palette: D, bold color field (teal).**

Overhead three-quarter angle on a gloved hand holding a small insulin-style syringe over a tray of mouse-muscle tissue samples. The nitrile glove is bright white, and the backdrop is a saturated teal lab bench surface with a soft sheen. Tiny clear microtubes sit in a rack, and a few contain a faint amber liquid. One thin electric green cap on a tube is the only green accent. The lighting is bright, even studio-like lab light with crisp, soft-edged shadows and a gentle highlight on the syringe barrel and a single hanging droplet at the needle tip. The depth of field is shallow, so the background tubes blur into teal. The mood is precise, focused and quietly hopeful, with no readable text or labels anywhere.

一次注射即可让年老小鼠的肌肉线粒体在1小时内恢复青春活力

一次注射 SS‑31（elamipretide）即可在一小时内把极老小鼠的肌肉线粒体能量产生恢复到相当于年轻鼠的水平。该结果来源于 2013 年的动物实验，而非人体试验。该肽对年轻肌肉影响不大，连续八天的给药才提升了老年鼠的耐力。在人类方面，elamipretide 已获 FDA 加速批准用于巴特综合征，但在 MMPOWER‑3 线粒体肌病试验中未达主要终点。下面我们一起看看这项研究的发现、局限以及为何市面上所谓的“灰色渠道”产品并不值得信赖。
