NITRAFLEX is a high‑stimulant pre‑workout powder by GAT Sport — designed to boost energy, focus, pump (blood flow), endurance, and performance when taken before workouts.
It’s “creatine‑free,” meaning the formula does not include creatine — but focuses on stimulants + nitric‑oxide boosting + energy/focus blends.
Here are some of the main ingredients (or ingredient‑complexes) in NITRAFLEX, and what they aim to do. Because many are inside “proprietary blends,” not all doses are fully disclosed.
| Ingredient / Blend | What It’s Supposed to Do |
|---|---|
| Caffeine (~ 325 mg per scoop) | Provides a strong energy & alertness boost — useful for powering through intense workouts. |
| Beta‑Alanine | Helps buffer lactic acid build‑up, supporting muscular endurance and delaying fatigue. |
| NO‑Precursor Complex (Citrulline / Arginine / Nitrosigine etc.) | Aims to improve blood flow / “pump”, vascularity, better nutrient/oxygen delivery to muscles. |
| Focus / Neuro Blend (e.g. L‑Tyrosine, DMAE, others depending on formula) | Intended to sharpen focus, boost mental energy, improve motivation and performance under high intensity. |
| Boron/Citrate (or Testosterone‑supporting Complex in older formulas) | Marketed — though evidence is limited — as supporting hormone balance & testosterone (claimed by GAT). |
Strong energy surge and mental focus, making gym sessions feel intense and “on.”
Noticeable “pump” and blood‑flow / vascularity — helpful for muscle fullness and workout feeling.
More endurance / stamina — able to push harder and do more reps or longer training sessions.
Because of the strong caffeine & stimulant load, it’s not ideal if you are sensitive to stimulants, or if you plan to train late — may affect sleep.
Many of the ingredients are inside “proprietary blends” — meaning exact dosages are not always disclosed, so it’s hard to assess how effective some components are.
Some reviewers think that certain ingredients (e.g. nitric‑oxide boosters) may be underdosed — possibly limiting the effectiveness of pump / vascularity claims.
Reported side‑effects by some users: jitters, “crash” after workout, possible heart‑rate increase, or uncomfortable stimulant effects — especially if dosage or tolerance not managed.
Because it’s high‑stim and potent, not recommended for beginners, or individuals with health conditions (especially cardiovascular, blood pressure, sensitivity to stimulants) — or for taking daily without breaks.
Typical serving: 1 scoop mixed with water (~250–300 ml), taken 20–30 minutes before workout.
Because of potency: if first time, start with ½ scoop to assess your tolerance — especially to caffeine / stimulants.
Do not exceed 1 serving per 24 h. Avoid taking it too close to bedtime to prevent insomnia / sleep disruption.
NITRAFLEX tends to suit:
Experienced gym‑goers who want a powerful pre‑workout boost (energy, pump, endurance)
People doing heavy lifting, intense training, high‑intensity sessions, or trying to push PRs
Those who respond well to stimulants and want strong mental focus + pump + energy in one formula
It is less ideal if you prefer mild or stimulant‑free pre‑workouts, or train late at night, or are new to pre‑workouts / sensitive to caffeine
