Nexus ObliterX Thermogenic Fat Burner

Nexus ObliterX is a thermogenic fat burner powder from Australian-owned Nexus Sports Nutrition. One 7 g scoop gives you 120 mg of caffeine, 2,000 mg of acetyl L-carnitine, 1,000 mg of L-tyrosine and 10 more actives for energy, focus and metabolism. ObliterX has only 13 calories and less than 1 g of sugar per scoop. Take ObliterX in the morning or before training. One tub gives you 40 serves in five flavours.

Why choose ObliterX fat burner

Nexus built ObliterX as a stimulant-powered formula for energy, focus and recovery, with 13 actives in every scoop. 120 mg of caffeine anhydrous gives you a clean lift, and the nootropics acetyl L-carnitine, L-tyrosine and Alpha-GPC keep your mind switched on. L-theanine smooths out the focus, while a blend of antioxidant-rich botanicals (green coffee bean, dandelion root, cocoa, grape seed and pterostilbene) adds metabolic support.

GBBGO® supports the carnitine pathway, the system your body uses to carry fat into your cells to be burned for energy, and black pepper extract boosts absorption of everything else. Vitamin B6 helps turn nutrients into energy. Together, ObliterX keeps you mentally dialled in and physically ready from the first rep to the last.

What ObliterX helps with

• Energy: 120 mg of caffeine per scoop, about the same as a strong coffee.
• Fat metabolism: 2 g of acetyl L-carnitine and 10 mg of GBBGO® to support the carnitine pathway.
• Focus: 1 g of L-tyrosine, 125 mg of Alpha-GPC and 120 mg of L-theanine.
• A light cut-friendly drink: 13 calories, 0 g fat and less than 1 g of sugar per scoop.

What's in one scoop (7 g)

Each scoop has 13 calories, 2 g of carbs, less than 1 g of sugar and 0 g of fat. The full label is in the nutrition panel image.

Key ingredients explained

• Acetyl L-carnitine (2 g): carnitine carries fatty acids into your cells, where they're burned for energy. The acetyl form also crosses into the brain, so acetyl L-carnitine supports focus too.
• GBBGO® (10 mg): the building block your body uses to make its own carnitine, which is why GBBGO is paired with acetyl L-carnitine.
• Caffeine and L-theanine (120 mg each): a classic pairing. Theanine takes the edge off the caffeine, so you get alert focus without feeling wired.
• L-tyrosine and Alpha-GPC: nootropics that support focus and drive when you're dieting or tired.

How to take ObliterX

Mix 1 scoop (7 g) with about 500 ml of cold water. Take ObliterX first thing in the morning or 15 to 30 minutes before training. Don't take more than one scoop a day, and avoid taking ObliterX late in the afternoon or at night, because the caffeine can keep you awake. New to fat burners? Try half a scoop first to see how you handle the caffeine.

Does ObliterX work as a pre-workout?

Yes. With 120 mg of caffeine, tyrosine and Alpha-GPC, ObliterX gives you a lighter pre-workout-style lift, which works well before cardio or a weights session. If you already take a stim pre-workout, don't take both on the same day, or you'll double up on caffeine. Pair ObliterX with a non-stim pump product instead.

What to take with ObliterX

• A non-stim pump: Nexus AMP3D 2.0 has no caffeine, so you can add AMP3D 2.0 to ObliterX before training for pumps and endurance.
• Protein: Booty N Buff Lean Protein or Nexus Super Protein help you hold on to muscle while you cut.
• Electrolytes: Nexus Hydration+ for long or sweaty sessions.

Who should take ObliterX?

ObliterX is a good fit for adults who are cutting or leaning out and want a moderate-caffeine thermogenic that also sharpens focus. ObliterX suits people who find big-stim fat burners too strong, since 120 mg of caffeine is about one strong coffee.

Side effects and who should avoid ObliterX

ObliterX contains caffeine, so you might feel jittery, restless or have trouble sleeping if you're sensitive or take ObliterX too late in the day. Count your coffee, energy drinks and pre-workout when working out your total caffeine. Some people get an upset stomach on an empty stomach; if that happens, take ObliterX with a small meal.

ObliterX is not suitable for children, or for women who are pregnant or breastfeeding. Talk to your doctor before using ObliterX if you have a heart condition, high blood pressure, anxiety, or take any medication. Don't take more than one scoop a day. If you compete in a tested sport, check with your sporting body first.
