A wide landscape editorial photograph of a sunlit minimalist gym corner with warm, natural morning light streaming through tall windows. In the foreground on a light oak wooden bench sits a small matte ceramic dish holding a few translucent amber softgel capsules, next to a brushed steel shaker bottle and a folded charcoal gray towel. The capsules catch the light with a soft golden glow, shallow depth of field blurring them slightly against the background.

In the softly blurred midground, a barbell loaded with black plates rests on a squat rack, with chalk dust lightly floating in the sunbeams. The walls are textured off-white plaster, and the floor is pale polished concrete. A potted green plant adds a touch of organic color near the window.

Laid casually beside the dish is an open notebook with a clean, hand-drawn bar chart in black ink: two bars of slightly different heights, one marked with a small question mark, suggesting uncertainty and interpretation. A slim pencil rests across the page. No readable text beyond simple marks.

The color palette is muted and modern: cream, warm beige, soft amber, charcoal, and sage green accents. The composition follows the rule of thirds, with the capsules and notebook in the lower left third and open negative space toward the upper right, ideal for headline overlay. Soft shadows, subtle film grain, and a calm, contemplative mood reminiscent of a contemporary health and science magazine. Shot as if with a 50mm lens at f/2.0, high-end lifestyle editorial aesthetic, clean and trendy, with no futuristic or sci-fi elements.

750 mgのPAで8週間、筋肉量が2.6%増加—ただし注意点あり

BY DR. GYMBRO · 2026年10月16日

小規模なパイロット研究で、トレーニング経験のある男性が1日750 mgのホスファチジン酸（PA）を摂取すると、8週間で除脂肪体重が2.6%増加した。一方、プラセボ群は0.1%しか増えなかった。スクワットの1RMもPA群で12.7%上昇し、プラセボ群の9.3%を上回ったが、統計的有意差は認められなかった。この結果の解釈と限界について解説する。

A landscape editorial still life on a warm, softly textured oatmeal-colored linen surface, photographed from a slightly elevated three-quarter angle in gentle morning window light. At the center sits a small matte ceramic dish in muted terracotta holding a handful of pale amber capsules, with a few spilled casually onto the linen. Beside it is a rustic wooden scoop holding a pile of fine, golden-tan powdered root extract. Behind these, a loose arrangement of raw Tongkat Ali root pieces, gnarled and fibrous with pale cream interiors and rough brown bark, rests on a slab of pale travertine stone.

On the left, a pair of older adult hands, seen only from the wrists down, with natural skin texture, hold a simple matte-black hand dynamometer in a relaxed grip. The tone is dignified and healthy, not athletic or posed. A sage-green ceramic mug of tea sits slightly out of focus nearby, with a thin curl of steam.

On the right, a minimalist open notebook with blank cream pages and a slim brass pen lies beside a sprig of dried eucalyptus. A small frosted glass jar adds a quiet pharmacy-apothecary note.

The palette is earthy and calm: warm beige, terracotta, sage, soft brown, and cream, with subtle brass accents. The shadows are long and soft, the depth of field shallow with a creamy blurred background of a sunlit neutral wall and a hint of a leafy plant. Negative space on the upper right suits headline overlay.

The style is modern wellness-journal photography, like a high-end health magazine or a Kinfolk-inspired lifestyle site: tactile, calm, and refined, with subtle film grain and natural color grading. There is no text, no logos, no futuristic elements, and no clinical lab equipment.

Tongkat Ali：1日400 mgを5週間摂取でテストステロンと握力が上昇

BY DR. GYMBRO · 2026年10月15日

Tongkat Aliはインターネット上で最も検索されるテストステロン向上サプリのひとつです。今回の小規模パイロットスタディでヒトデータが示されました。57〜72歳の活動的な成人25名が1日400 mgの抽出物を5週間摂取した結果、総テストステロンと遊離テストステロンが上昇し、握力も向上しました。女性の遊離テストステロンの上昇はSHBGの低下が原因と考えられます。ただしプラセボ群が設定されていないため、確証というよりは有望な結果と言えるでしょう。以下に研究概要・注意点・活用方法をまとめました。
