Reported Mechanism (Provisional)

Mechanism of Action

LJ100's eurypeptides and glycosaponins stimulate the hypothalamic-pituitary-gonadal axis, increasing luteinizing hormone secretion from the anterior pituitary. This enhanced LH release promotes Leydig cell testosterone production while simultaneously reducing cortisol levels that typically suppress androgen synthesis. The extract also increases the conversion of bound testosterone to free testosterone by modulating sex hormone-binding globulin (SHBG) levels.

Clinical Narrative (Provisional)

A 12-week randomized controlled trial with 109 men aged 30-55 showed LJ100 increased total testosterone by 37% and free testosterone by 34% at 300mg daily. Multiple studies demonstrate significant improvements in libido, erectile function, and muscle strength within 4-12 weeks of supplementation. Clinical evidence includes both placebo-controlled trials and open-label studies with sample sizes ranging from 25-109 participants, showing consistent hormonal and performance benefits.
