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.

This supporting blend is included to complement Testofen® and LJ100®. It is not the primary researched stack. The clinical doses and published human trials above apply to Testofen® 600 mg and LJ100® 200 mg.
Most brands use "fairy dust" doses. We use the exact amounts used in the clinical trials.

LJ100® is a standardized Tongkat Ali root extract. The U.S. patent (7,132,117) was granted in 2006, from work filed in 2000–2002 by MIT and the Government of Malaysia. Human studies on this extract start in the early 2000s. It has been sold under the LJ100® name since 2002 and received self-affirmed GRAS status in 2013.
Testofen® is a standardized fenugreek seed extract. It has been sold under that name since 2005. The first published human trial was 2011.
Ginger Jacked uses those same branded extracts at the trial doses: Testofen® 600 mg and LJ100® 200 mg. A patent is not an FDA safety review. It is evidence these are not last year's mystery powder. The plants themselves — fenugreek seed and Tongkat Ali root — have much longer traditional use.
In the published trials at these doses, the extracts were generally well tolerated. Some LJ100 studies also checked liver enzymes, kidney function, blood counts, and PSA and did not see a difference versus placebo in those groups. That is not a clinical trial of this finished bottle. If you have a medical condition or take prescription medication, ask your doctor first.
