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 of PA Added 2.6% Lean Mass in 8 Weeks—But There's a Catch

BY DR. GYMBRO · Oct 16, 2026

One small study found that trained men taking 750 mg of phosphatidic acid daily gained 2.6% lean mass in eight weeks, while the placebo group gained just 0.1%. Squat strength also rose more with PA, 12.7% versus 9.3%. But the authors' own conventional analysis found no significant differences. Their conclusions rest on a more lenient statistical method applied to just 16 men. Here is the dose, the results, and why this pilot study is a promising signal rather than proof.

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: 400 mg for 5 Weeks Lifted Testosterone and Grip Strength

BY DR. GYMBRO · Oct 15, 2026

Tongkat Ali is one of the most-searched testosterone boosters on the internet, and a small pilot study gives it some real human data. Twenty-five active adults aged 57-72 took 400 mg of extract daily for 5 weeks, and both total and free testosterone rose, along with handgrip strength. Women's free testosterone climbed too, apparently because SHBG dropped. But there was no placebo group, so this is promising rather than proof. Here is what the study found, what it can't tell you, and how to approach it sensibly.
