A pre-workout and daily endurance elixir combining Cordyceps mushroom and Rhodiola Rosea — two of the most researched natural compounds for physical energy, stamina, and recovery. No caffeine, no stimulants, no crashes. Just clean, adaptogenic support for your energy systems and lung capacity. Alcohol-free 30:1 dual extract, formulated by an Australian nutritionist.
Most energy supplements work by stimulating your nervous system — caffeine, pre-workout blends, or sugar-loaded drinks that produce a temporary spike followed by a drop. Stamina Surge works differently. It targets the underlying energy systems your body uses to produce and sustain physical output: how efficiently your cells generate energy, how well your lungs deliver oxygen, and how effectively you recover between efforts.
Cordyceps militaris is the primary ingredient — a medicinal mushroom with a strong track record in sports science research. Studies on Cordyceps supplementation have shown measurable improvements in VO2 max (a key measure of aerobic capacity and oxygen efficiency) and time-to-exhaustion during sustained exercise. It works by supporting ATP production — ATP being the energy currency your cells use for every physical action — and by improving the efficiency of oxygen uptake in the lungs. The result is cleaner, more sustained physical energy without the stimulant mechanism.
Rhodiola Rosea is an adaptogen that reduces the perception of effort during exercise and supports faster recovery. It's been studied for its effects on physical fatigue, mental endurance, and stress resilience — making it particularly useful for people who train hard and also need to perform cognitively throughout the day. Grapefruit extract is added to improve bioavailability of both compounds.
The pairing of Cordyceps and Rhodiola is specific and deliberate. Cordyceps handles the energy production and oxygen side of performance. Rhodiola handles the fatigue and recovery side. Together they address both what limits you going into a session and what holds you back coming out of one.
Cordyceps is one of the most studied mushrooms in the context of physical performance — and the evidence is unusually consistent for a supplement. The fruiting body form used here (Cordyceps militaris) is the most potent and researched variety, and the 30:1 extraction ratio means each 1ml serve contains the active compound equivalent of 30g of whole mushroom. Unlike caffeine or stimulant-based pre-workouts, the benefits build with consistent use rather than peaking and crashing.
Rhodiola's adaptogenic effects on fatigue are well-documented across both physical and mental contexts — it doesn't directly stimulate energy, but it helps your body regulate the stress response that makes sustained effort feel harder over time. For people juggling training with demanding work or life schedules, this dual effect is particularly relevant.
Active (per 1ml serve): Cordyceps Militaris Mushroom 30:1 Dual Extract equiv. 30,000mg, Rhodiola Rosea Root Extract, Grapefruit Extract (Citrus x paradisi, high in naringin for bioavailability).
Other ingredients: Distilled Water, Vegetable Glycerin, Citric Acid, Natural Flavour, Stevia Extract, Potassium Sorbate, Sodium Benzoate.
Vegan · Caffeine-free · Alcohol-free · No fillers, grains, or synthetic additives · Gluten free · Non-GMO · Whole fruiting body only · Tested for heavy metals and microbials
Format: 60ml liquid dropper bottle, approx. 60 serves (1ml per serve).
For exercise: Take 1 full dropper (1ml) 30 minutes before training. Hold under the tongue for 15 seconds before swallowing for faster absorption, or add to a pre-workout drink.
For daily energy support: Take at any point during the day — morning or early afternoon works well. Like all adaptogens, the effects of Rhodiola and Cordyceps build with consistent daily use over 3–6 weeks, even on rest days.
Important: Contains grapefruit extract, which can interact with certain medications. Consult your healthcare provider if you take any medications.
