The Science Behind Ginger Jacked

Two patented, clinically studied actives at the exact doses used in human trials.

No fairy dust. No vague "proprietary blends." Just the papers.

Ginger Jacked is built around Testofen® 600 mg and LJ100® 200 mg — the same branded extracts and doses studied in published human research. Below is the research we rely on, with links to the original papers.

TESTOFEN®

600 mg per daily serving

Testofen® is a standardized fenugreek seed extract studied in healthy adult men for testosterone, sexual function, strength, and body composition.

What the research found

  • — In a 12-week randomized, double-blind, placebo-controlled trial of 120 healthy men ages 43–70, 600 mg per day increased total and free testosterone versus placebo and improved measures of sexual function.
  • — In a separate 8-week resistance-training study, men taking 600 mg per day improved strength, lean mass, body composition, and testosterone from baseline.

LJ100® TONGKAT ALI

200 mg per daily serving

LJ100® is a standardized Eurycoma longifolia (Tongkat Ali) root extract studied for testosterone support, fatigue, sexual well-being, and quality of life in aging men.

What the research found

  • — In a randomized, double-blind, placebo-controlled multicenter study, aging men received placebo, 100 mg, or 200 mg daily for 12 weeks.
  • — The 200 mg group showed increases in total testosterone at weeks 4, 8, and 12 versus placebo, plus improvements in fatigue and quality-of-life measures.
