Below is every ingredient in the formula, what it is, and what it is genuinely studied for. Where the support is traditional rather than clinical, this page says so — which is three of the five.
L-Arginine
Mechanistically establishedA semi-essential amino acid and the direct substrate for nitric oxide production. Your body converts L-arginine into nitric oxide through nitric oxide synthase; nitric oxide then signals the smooth muscle lining your blood vessels to relax, widening the vessel and improving flow. This is the most mechanistically well-established ingredient in the formula and the one with the clearest relevance to circulation, exercise capacity and cardiovascular wellness. Dietary sources include meat, poultry, fish, nuts, seeds and legumes; demand rises with physical stress, injury and age.
Ashwagandha
Randomised human trialsAn adaptogenic herb central to Ayurvedic practice for more than two millennia and among the most studied botanicals in the men's wellness category. It has been examined in randomised controlled trials for the body's response to everyday stress, sleep quality and perceived energy. It earns its place for a practical reason: chronic stress load is one of the largest real-world drains on a working man's energy, drive and recovery, and it is one of the few such inputs a botanical can plausibly influence.
Maca Extract
Traditional use, early researchA cruciferous root cultivated above 4,000 metres in the Peruvian Andes, where it has been grown and eaten for centuries and valued specifically for supporting energy and physical endurance in a punishing environment. Modern interest centres on its glucosinolates and macamides. The research base is early-stage rather than definitive, and this page treats it as promising traditional use rather than settled science.
Catuaba Extract
Traditional and preclinicalOne of the most widely used herbal tonics in Brazil, traditionally taken to support energy, vitality and general well-being. Its evidence base is traditional and preclinical. It functions as a stamina-side complement to Maca rather than as a headline actor, and an honest label presents it that way rather than dressing it up as clinically proven.
Muira Puama Extract
Traditional useKnown in the Amazon basin as “potency wood”, Muira Puama has a long record in traditional herbal practice for supporting men's vitality and vigour, and it remains a standard inclusion across the category. Being straight about the evidence: human clinical data is limited, and its inclusion rests primarily on traditional use rather than trial outcomes.
Reading the label properly
Each jar holds 30 gummies. Every serving delivers 82 mg of concentrated extract, which the label states is equivalent to approximately 567 mg of dry powders. Extracts are concentrated: a 7:1 extract means seven grams of raw herb produced one gram of extract, so a smaller milligram figure can represent a much larger quantity of original plant material.
Two habits worth adopting when comparing any two supplement labels:
- Check extract versus raw powder. A big number on a raw-powder label is not automatically a stronger product than a smaller number on an extract label.
- Check for a proprietary blend. A single total figure covering several ingredients hides how much of each you are getting. Named ingredients are the baseline for a label worth trusting.
Always read the current jar label before use. Manufacturers can revise a formula, a gummy base or a serving size between production runs, and the label in your hand always overrides any website — including this one.
What is not in it
- No caffeine or added stimulants
- No prescription drug analogues — a real concern in this category, where the FDA regularly publishes notifications about male-enhancement products found to contain undeclared sildenafil or tadalafil
- No forced-subscription trial packaging
