Study Overview
Brief Summary
Given that testosterone is a key modulator of muscle protein synthesis and overall anabolic response to resistance training, any natural intervention that boosts testosterone levels could logically contribute to improved exercise performance, lean muscle gain, and subjective vitality. 13 However, despite encouraging preclinical and ethnopharmacological data, clinical validation of Curculigo extract in human participants-especially in the context of exercise and lifestyle enhancement-is lacking. A novel extract of Curculigo orchioides (commercially known as RhizomK™) has been developed. This randomized, double-blind, placebo-controlled study seeks to bridge this crucial gap by evaluating the efficacy and safety of RhizomK™ supplementation in healthy, physically active males. The findings of this study have the potential to substantiate RhizomK™ as a scientifically supported dietary intervention for enhancing hormonal balance, physical performance, and well-being in men who are not candidates for pharmacological therapy but are seeking to optimize their health through lifestyle and supplementation.

Arms & Interventions
Group RhizomK
Intervention: RhizomK (Drug)
Group Placebo
Intervention: Plcebo (Other)
Outcomes
Primary Outcomes
Serum testosterone levels
Time Frame: 4 weeks
A basal pre- intervention Saliva sample will be obtained for analysis of basal (resting) testosterone levels. One hour after ingestion of the assigned study product, the subject will undergo an acute resistance exercise routine. Resistance exercise will include the Leg Press. The post resistance-exercise session Salivary/Serum Testosterone samples within \~30 minutes of completing the exercise routine will be collected.
Secondary Outcomes
- Serum cortisol levels(4 weeks)
- Quality of life using SF-36 (Short Form 36-Item Health Survey)(4 weeks)
- Exercise performance(4 weeks)
- Adverse effect(4 weeks)
