Stacker2 Octagon Pre-Workout

How Octagon Pre-Workout supports your objectives

⚡ Fight-specific stimulation and mental focus Octagon delivers 300 mg of caffeine per serving, a dose calibrated for high-intensity combat sports sessions. Combined with Zynamite® (mango leaf extract, 120 mg), which has been studied for its ability to support cognitive speed and reaction time, this formula primes the nervous system for sharp decision-making under pressure — not just lifting heavy.

💪 Power output and explosive force With 3 g of creatine monohydrate per serving, Octagon helps replenish phosphocreatine stores, directly supporting ATP regeneration during maximal efforts. This means more output per strike, per sprint, and per explosive change of direction during sparring or conditioning rounds.

🔁 Endurance and fatigue resistance Beta-alanine (2 g) buffers muscle acidity by increasing intramuscular carnosine levels, helping athletes sustain high-intensity work for longer. L-citrulline malate (4 g) supports nitric oxide production, improving blood flow to working muscles and accelerating lactate clearance between rounds.

🧠 Stress adaptation and resilience under pressure Rhodiola rosea extract (200 mg) is an adaptogen with strong evidence for reducing perceived effort and mental fatigue during prolonged exercise. Paired with taurine (1 g) and L-tyrosine (500 mg) — a precursor to dopamine and noradrenaline — this combination supports mental composure and sustained drive throughout training.

🔬 Superior absorption via patented technology AstraGin® (35 mg) enhances intestinal absorption of amino acids, creatine, and vitamins. BioPerine® (5 mg) further amplifies bioavailability by inhibiting metabolic enzymes that break down active compounds too early. Together, they ensure every ingredient reaches its target tissue at optimal concentration.

🎯 Goal guide

Serving suggestion

Mix 2 scoops (13 g) with 250–300 ml of cold water. Shake or stir vigorously until fully dissolved. Consume the full serving in one go, 20–30 minutes before the start of your training session or sparring. Do not exceed 2 scoops per day.

Note: this product is hygroscopic. Keep the bottle tightly closed after use and do not remove the silica bag. Store in a cool, dry place.

Best times to enjoy it

🕖 20–30 min before training: optimal timing for caffeine and citrulline to reach peak plasma levels

🥊 Before sparring or technical work: cognitive sharpness from Zynamite® and tyrosine is most relevant here

🚫 Avoid after 4 PM: 300 mg caffeine can disrupt sleep quality if taken too late in the day

❌ Not recommended on rest days: this is a performance primer, not a daily supplement

Daily protein target reminder

Current evidence supports 1.6 to 2.2 g of protein per kg of body weight per day for active individuals. Combat athletes should aim for the higher end of this range on training days.

Goal-specific guidance

For weight loss / cutting: Octagon can be used to maintain training intensity during a caloric deficit. The caffeine and Rhodiola combination supports energy and mood when calories are restricted. Avoid adding sugar to the mix. Prioritise adequate protein intake (2.0–2.2 g/kg) to preserve lean muscle.

For mass gain: Use Octagon before your most demanding sessions. The 3 g creatine dose contributes to daily creatine loading (target: 5 g/day total). Pair with a post-workout meal containing 30–50 g of fast-absorbing protein and 60–80 g of carbohydrates within 30–45 minutes of training.

🏅 Sport Nutrition "Did you know?"

Zynamite® (the mango leaf extract in Octagon) is not just a stimulant — it has been studied as a potential synergist with caffeine, amplifying its effect at lower doses. This means you get sharper focus with less of the jittery edge typically associated with high-caffeine formulas. For fighters, that balance between alertness and controlled composure can be the difference between a smart round and a reckless one.

Active ingredients per serving (2 scoops / 13 g)

Q1 — Can I take Octagon every day? Octagon is designed for use on training days only, not as a daily supplement. With 300 mg of caffeine per serving, regular daily use can lead to tolerance build-up and reduced sensitivity over time. Taking it exclusively before structured sessions also preserves its effectiveness. A caffeine-free day at least twice per week is recommended for most athletes.

Q2 — Will beta-alanine cause a tingling sensation? Yes, the tingling or prickling feeling (called paraesthesia) is a normal and harmless side effect of beta-alanine at doses of 2 g or more. It typically appears in the face, neck, and hands and fades within 20–30 minutes. It is not a sign of an allergic reaction. Athletes who are sensitive to this effect can start with 1 scoop and gradually increase to the full dose.

Q3 — Is Octagon safe for competitive athletes subject to doping control? Stacker2 Europe runs an independent anti-doping laboratory testing programme and publishes all results on their website. Octagon is included in this programme. That said, athletes competing under WADA-regulated federations are always advised to verify the most recent batch test before use, as supplement contamination risk can never be fully eliminated.

Q4 — Can I stack Octagon with a protein shake or creatine supplement? Yes. Octagon provides 3 g of creatine monohydrate, which contributes to the recommended daily dose of 5 g. If you take a separate creatine supplement, reduce or skip the additional dose on days you use Octagon to avoid exceeding 5 g total. Pairing with a post-workout protein shake is perfectly safe and encouraged.

Q5 — Is Octagon suitable for fighters who compete in weight categories? Yes, with some considerations. Octagon is stimulant-based and should not be taken during active weight-cut phases where water restriction is in play, as high caffeine intake promotes fluid loss. Crystal pink salt is included to support electrolyte balance. For fighters in the final days before a weigh-in, consult with a sports dietitian before using any stimulant pre-workout.
