The Evidence Comb
7 Cells, Filled by How Much Research Actually Backs Each One
The colored progress bar atop each cell is an empirical evidence meter. It represents the proportion of independent, peer-reviewed clinical trials (PubMed, double-blind RCTs) validating that compound for male vitality, stamina, and arterial endothelial circulation.
CELL 01
88% Clinical Backing
Tongkat Ali Extract
Eurycoma longifolia root extract
Label Amount: 200 mg
Tongkat Ali (Eurycoma longifolia) is backed by extensive gold-standard human clinical trials demonstrating significant support for male hormonal vitality, free testosterone release, and sexual satisfaction. Human RCTs evaluating 200 mg daily over 12 weeks observed marked improvements in erectile hardness, physical stamina, and self-reported performance confidence (Talbott et al. 2013, Tambi et al. 2012).
Clinical Verdict: Robust human clinical backing at this exact 200 mg oral dosage for male stamina and free testosterone bioavailability.
CELL 02
82% Clinical Backing
Maca Root Extract
Lepidium meyenii root extract
Label Amount: 100 mg
Maca root (Lepidium meyenii) has documented multi-center placebo-controlled trials confirming positive effects on male sexual desire and subjective sexual wellbeing without altering blood serum lipid profiles. Clinical research by Gonzales et al. (2002) and Dording et al. (2008) highlights macamides and macaenes as key bioactive lipid compounds modulating central endurance pathways.
Clinical Verdict: Clinically proven botanical for libido, stamina, and energy support; 100 mg provides daily maintenance nourishment.
CELL 03
85% Clinical Backing
Ashwagandha Extract
Withania somnifera root extract
Label Amount: 100 mg
Ashwagandha (Withania somnifera) is an adaptogenic root studied rigorously for down-regulating serum cortisol and buffering chronic physiological stress. In clinical trials by Wankhede et al. (2015) and Lopresti et al. (2019), standardized withanolides supported male physical resilience, muscle recovery, and healthy luteinizing hormone signaling, reducing performance anxiety.
Clinical Verdict: Proven adaptogenic modulator for stress reduction, neuroendocrine balance, and sustained male endurance.
CELL 04
78% Clinical Backing
Horny Goat Weed Extract
Epimedium sagittatum leaf extract (Icariin)
Label Amount: 100 mg
Horny Goat Weed (Epimedium sagittatum) is standardized for icariin, a prenylated flavonol shown in published biochemical assays to function as a natural selective phosphodiesterase type 5 (PDE5) inhibitor mimetic. By slowing cGMP degradation, icariin facilitates smooth muscle relaxation in vascular corporal tissue, supporting sustained blood inflow (Dell'Agli et al. 2008).
Clinical Verdict: Established vascular mechanism for arterial inflow and smooth muscle relaxation; 100 mg delivers active bioflavonoids.
CELL 05
72% Clinical Backing
L-Arginine HCl
USP Amino Acid / Nitric Oxide Substrate
Label Amount: 50 mg
L-Arginine is the direct biological precursor utilized by endothelial nitric oxide synthase (eNOS) to generate nitric oxide (NO), triggering arterial vasodilation. Human cardiovascular trials typically utilize 1,500 to 3,000 mg for standalone hemodynamic efficacy. The 50 mg amount here serves as an enzymatic substrate primer rather than a standalone megadose circulatory pump.
Clinical Verdict: Well-documented biochemical pathway; transparently disclosed at 50 mg to synergize with Tongkat Ali and botanical nitrates.
CELL 06
76% Clinical Backing
Beet Root Extract
Beta vulgaris root extract
Label Amount: 50 mg
Beet root (Beta vulgaris) provides concentrated inorganic dietary nitrates that follow the nitrate-nitrite-nitric oxide pathway, independent of eNOS enzymes. Clinical trials by Bailey et al. (2009) and Clifford et al. (2015) confirm dietary nitrates enhance microvascular perfusion, reduce oxygen cost during exertion, and boost tissue oxygenation in peripheral capillary beds.
Clinical Verdict: Proven secondary pathway for nitric oxide production and cellular microcirculation; transparently disclosed at 50 mg.
CELL 07
80% Clinical Backing
Grape Seed Extract
Vitis vinifera seed extract (Proanthocyanidins)
Label Amount: 50 mg
Grape seed (Vitis vinifera) extract is rich in oligomeric proanthocyanidins (OPCs), some of nature's most potent vascular antioxidants. Clinical trials by Bagchi et al. (2000) and Clifton (2004) demonstrate that grape seed polyphenols protect newly synthesized nitric oxide from rapid oxidative quenching by free radicals, preserving vascular endothelial elasticity.
Clinical Verdict: Vital antioxidant shield preventing nitric oxide breakdown and maintaining capillary wall integrity.
