Formutech Lean-EFX

Lean-EFX, the classic fat burner from Formutech Nutrition, is back in all it’s DMAA-infused glory

Formutech Nutrition grew to popularity with one of the most popular and effective DMAA-infused fat burners on the market. Then, for a time it went away, when the FDA sent letters over the appetite-reducing stimulant.

But, thanks to parent company Hi-Tech Pharmaceuticals and their ongoing efforts to battle the FDA

The classic Lean-EFX is back in its original form… DMAA and all!

The full breakdown is below, but before we get to it, take a moment to check the best deal and sign up for alerts from PricePlow:

Lean-EFX Ingredients

Lean-EFX is a mixture of three proprietary blends that helps increase energy, elevate mood, and make achieving a slimmer physique that much easier.

Note: Doses listed below are based on 1 serving (i.e. 1 capsules).

  • Next Gen EFX (375mg)

    • 1,3,7-trimethylxanthine

      Formutech Lean-EFX Ingredients

      Lean-EFX is comprised of three proprietary blends which improve mood, focus, and most importantly, fat burning.

      1,3,7-trimethylxanthine is a fancy chemical name better known as caffeine. It’s been shown to be effective for boosting physical endurance, reducing fatigue, enhancing mental alertness, and even supporting weight loss.[1]

      Caffeine is an all-around fantastic ingredient that keeps you awake, motivated, and in the zone. There’s not much to cover that you don’t already know, so we’ll get moving right along to our next ingredient!

    • Cassia Nomame

      Native to China, but grown around the world, Cassia Nomame is a medicinal plant widely used for its weight loss and diuretic benefits. Clinical trials on Cassia have shown it’s an effective anti-inflammatory, but more importantly, it exerts a powerful diuretic effect, increasing urine output by subjects.[2]

    • Taraxacum

      More commonly known as Dandelion, Taraxacum officinale is one of the most commonly used water-ridding agents used in fat burners and diuretics that helps the body flush out excess water.[3] In addition to increased urine output, frequency is also increased for a period up to 5 hours post ingestion.[4]

      Taraxacum also improves glucose uptake in skeletal muscle[5], ensuring any carbs you consume go towards muscle growth, and not stored as fat around your waist.

      One last thing to note, taraxacum is a rich source of potassium, one of the vital minerals required when shedding excess water weight.

    • Green Tea

      EGCG improved glycemic control in mice

      EGCG improved glycemic control in mice. Shown are fasting blood glucose levels (A), fasting plasma insulin levels (B), blood glucose concentrations (C, D) and plasma insulin concentrations (E, F) during an oral glucose tolerance test (OGTT).

      Green tea is long known as a strong cardiovascular system supporter, with the research to back it up. On top of the long list of health benefits, it’s also a powerful weight loss aid.

      Studies on green tea not it supports fat burning primarily due to EGCG’s role in promoting lipolysis in the body.[6,7] Plus, you’ll also get a mild boost in energy from the minor amount of caffeine in it.

    • Bearberry

      Bearberry, otherwise known as Uva ursi or bear’s grape, acts as a natural diuretic that increases urine output.[8] Historically, it’s used to to treat cystitis, urolithiasis, and a number of other urinary tract infections.

    • Niacin

      Niacin, a.k.a. Vitamin B3, is a water-soluble B vitamin that helps the body convert food into fuel (glucose), which is used by the body to produce energy. B vitamins also help the body with the breakdown of fats and protein.

  • Thermo EFX (240mg)

    • 1,3 Dimethylamylamine

      Formutech Lean-EFX Box

      Lean-EFX is one of the strongest single capsule fat burners on the market. Take one and watch hunger disappear.

      The powerhouse ingredient that makes everyone love Lean EFX, 1,3 Dimethylamylamine (DMAA) is an aliphatic amine — a class of compounds well known for their stimulating effects that’s found in certain Chinese Geraniums but is typically manufactured synthetically. It functions best when used along with caffeine (which we discussed above).

      DMAA is a great stimulant and focus enhancer, and anecdotally, it’s been said to have fairly potent appetite suppression characteristics. We’re not really sure how much DMAA (or caffeine for that matter) is in Lean-EFX, but if we had to venture a guess, we’d guess there’s around 50mg per capsule. — again, that’s just a guess.

      If you’re looking for a DMAA-free version, Formutech also has Lean EFX Refined, but it’s far less popular because this ingredient is one of the main reasons it’s so popular.

    • Thiamine Disulfide

      Another B vitamin, Thiamin is also known as Vitamin B1. Aside from the energy converting roles discussed above, including B vitamins is also useful due to the natural diuretics included in Lean-EFX.

      B vitamins are excreted through the urine, so including extra B vitamins in Lean-EFX works to support the body’s basic nutrient needs.

    • Phyllanthus emblica

      Formutech Jeanette Affolter

      Happy Monday from Formutech athlete Jeanette Affolter!

      Phyllanthus emblica, also referred to as emblica officinalis or simply Amla, is an Ayurvedic herb traditionally used for to enhance vitality and cognition in additional to promoting longevity.

      Research into the herb increases glucose uptake into adipocytes (fat cells).[9] Other research on the herb notes reduced postprandial glucose as well as fasting glucose levels.[10]

    • Bitter Orange

      Bitter orange (Citrus Aurantium) , etc) contain a number of bioactive compounds that work as beta-receptor agonists. Beta-2 and Beta-3 adrenergic receptor agonist trigger lipolysis, a process that frees stored fatty acids, releasing them into the bloodstream to be used by the body for energy.[11,12]

      You’ll essentially be “burning fat” for fuel during low intensity activities, like watching tv or doing the laundry.

  • NeuroTherapy EFX (90mg)

    • 5-HTP

      Frequently seen in sleep aids, 5-HTP, short for 5-hydroxytryptophan, is a precursor to serotonin commonly used to provide a sense of well-being and overall contentment. Sufficient serotonin levels boost production of melatonin, and since 5-HTP is required for serotonin production, it stands to reason that consuming 5-HTP not only improves sleep, but mood and cognitive functioning as well.[13]

      Dieting can cause people to be cranky and irritable, including a bit of 5-HTP can help keep you feeling chipper even when you’re on poverty macros.

    • N-Acetyl L-Tyrosine

      Formutech Natural-EFX Banner

      Step up your fat burning game even further when stacking the stim-free Natural-EFX with Lean-EFX.

      N-Acetyl L-Tyrosine (NALT) is the acetylated form of L-Tyrosine, an amino acid commonly used as a focus-booster. Tyrosine supports the production of several powerful catecholamines such as epinephrine, dopamine, and norepinephrine (noradrenaline).[14]

      The cascade of neurotransmitters stimulate the sympathetic nervous system and the central nervous system, further boosting metabolic rate and thermogenesis. Unfortunately, the dose included here isn’t anywhere close to what we normally see in efficaciously dosed pre workouts, so you may not feel a ton of focus here.

    • Panax Ginseng 80%

      The last ingredient in Lean-EFX is another mood elevator — the ancient Chinese medicine Panax Ginseng. Clinical trials using ginseng document positive effects on mood, reaction time, and fatigue.[15] Other research shows that ginseng can help reduce appetite and control blood sugar levels.[16,17]


Take one (1) capsule daily upon waking. Do not take on an empty stomach or too late in the day, and do not mix with other stimulant-based products – especially no mixing with pre workouts, and don’t even mix it with coffee!

Per Formutech’s recommendations, don’t take Lean-EFX for more than 45 consecutive days without a 30 day break in between.


Lean-EFX is a proven and effective fat burner that helps build an athletic physique and can help chisel away the pounds of goo that have accumulated during the winter bulk. You’ll feel better while burning fat, and be more productive during the day too!

We just wished the DMAA and caffeine doses were disclosed…
