Green Stinger Ephedra Review

Green Stinger ephedra is marketed as a potent ECA (ephedra, caffeine, and aspirin) stack. This combination was very popular in the 1980’s and 1990’s among bodybuilders who wanted to cut weight quickly during their “cutting cycles”.

The caffeine and aspirin were purported to extend the efficacy of ephedrine (the active ingredient found in ephedra), while also minimizing potential side effects.

While ephedra containing ephedrine can no longer be used in supplements, Green Stinger provides a different source of ephedra plant extract from a species that does not contain any of the banned alkaloids.

This supplement also contains a number of additional energy-enhancing ingredients in a weight loss stack. Stacking can have synergistic benefits by providing ingredients that potentiate each

Among its list of ingredients include:

  • 27 mg of ephedra extract
  • 170 mg Bitter Orange (citrus aurantium)
  • 30% Synephrine extract (chemical formula C9H13NO2) – Synephrine is similar in nature and behavior as ephedrine, but not quite as strong. It’s most commonly known as Bitter Orange, and behaves like a thermogenic fat burner.

Synephrine is an adrenergic agonist that acts on the sympathetic nervous system. It’s primarily used in medical scenarios for the treatment of asthma, nasal congestion, and as a vessel constrictor in cases of cardiovascular circulatory failure. [1]

It is believed to have some of the same thermogenic properties as ephedrine, but is purported by some sources to be safer.

Green Stinger Ingredients

Other ingredients in Green Stinger ephedra include:

  • 150 mg Acacia Rigidula
  • 150 mg phenylethylamine HCL
  • 100 mg Theobroma CoCoa
  • 120 mg Green Tea extract

The Acacia Rigidula herbal component comes from a small shrub/tree of the Acacia species that can be found growing in the southwestern United States and down into the desert climates of Mexico.

As of 2016, the U.S. FDA deemed this a new dietary ingredient, but they have concerns regarding its similarity to BMPEA or beta-methylphenylethylamine, which the FDA deems an unlawful dietary ingredient. [2]

The product also contains a number of herbal ingredients including but not limited to:

  • Proprietary Yohimatrix™: Yohimbine HCL, Alpha Yohimbine, and 11-Hydroxy
  • Pure White willow bark extract (300 mg)

It also contains what the manufacturer calls a proprietary TriENG mixture of 300 mg strength: 200 mg of total caffeine composed of Kola Nut extract, plus Guarana extract and Yerba Mate.

Also note that this supplement does not contain any actual Aspirin, which is needed for it to be considered an ECA stack. Instead, Green Stinger uses white willow bark which contains the same active ingredient of salicin.

Because aspirin can act as a blood thinner and many are sensitive to it, White willow bark extract is often substituted as the aspirin ingredient in a number of popular ephedra supplements today.

While marketed as an ECA product, many don’t contain any aspirin – substituting other ingredients such as the natural analgesic White willow bark instead.

Results for Weight Loss

The manufacturer of Green Stinger ephedra promotes a number of results with use that include:

  • Increased energy
  • Enhanced sensation of well-being
  • Accelerated weight loss
  • Reduced body fat stores

The product is designed to support fat loss and can be used at any time, but is especially beneficial as a pre-workout supplement.

The ingredients in Green Stinger ephedra are designed to boost metabolism by stimulating the activity of adrenergic alpha agonists and activating their receptors. It acts as a sympathomimetic, primarily affecting the sympathetic nervous system.

A few studies have been performed on the effects of synephrine or Bitter Orange as a pre-workout dietary supplement.

One study determined that when used appropriately, the substance is well tolerated by healthy individuals. It does have the potential to increase resting energy expenditure, with the participants in the study claiming higher cognitive outlook in regard to their output of energy and performance.

Very few benefits were noted in a number of specific exercises including sprints, leg press weight lifting, or bench press lifting volumes. [3]

One small study attempted to gauge the safety of use in regard to the cardiovascular system. Another small study was conducted with 18 subjects (nine males and nine females) taking 49 mg p-synephrine (Bitter Orange) and a placebo-controlled, crossover in double-blind study.

While no negative effects were noted, and the amount of caffeine from various sources was reported by participants, it was determined that the synephrine used for the study (49 mg) did not have a stimulative effect on basic cardiovascular functions including heart rate and blood pressure. A minimal decline in diastolic blood pressure did occur following one hour of exercise during the trial. [4]

Ephedra Extract Effects

The other notable component in Green Stinger ephedra is the ephedra extract. Ephedra comes from a plant called ephedra sinica was more commonly known as Ma Huang.

Ma Huang is well-known in the world today as a beneficial weight loss compound, though its history of usage dates back thousands of years in Asia, India, and to a lesser degree, to historical usage in the United States. The American species Ephedra viridis, is less potent than the Asian species.

Ephedra, in traditional Chinese medicine practices, was used to treat a number of ailments, most commonly those that involve lung function and or breathing difficulties.

In the United States, it was determined that two alkaloids of ephedra (ephedrine and pseudoephedrine) contributed to a number of adverse reactions, cardiovascular issues, and in some cases, has been associated with the death of several individuals.

In 2004, the US Food and Drug Administration banned sale of any dietary supplements containing ephedrine alkaloids.

However, ephedra – removed of the alkaloids ephedrine and pseudoephedrine – is not banned, and is found in a huge number supplements today, most often touted as an effective weight-loss drug.

Ephedra in varying milligram strengths is found in a number of products sold online and off.

Green Stinger ephedra, containing 27 mg ephedra, is considered a safe dosage, when used properly. Other versions containing ephedra offer higher milligram strengths of ephedra up to and exceeding 50 mg per tablet.

Ephedra and ephedrine-like products continue to be popular for their potential to act as an appetite suppressant as well as a fat-burning agent.

Positive reviews in regard to its use are found throughout the Internet, but most success stories also mention that adhering to a balanced and nutritious diet as well as adequate amounts of exercise and intensity provides the best results.

The National Institutes of Health, Office of Dietary Supplements, does concur with the opinion that supplements containing ephedra as well as botanicals that contain caffeine can provide modest weight loss within six months, but no studies have been conducted recently to determine the maintenance or ability to sustain that weight loss past the six-month mark.

Green Stinger Ephedra Reviews

As with any product, user reviews for Green Stinger ephedra are mixed. Using a general rating system found online (one through five stars), the average rating for this product hovers between 3.0 to 3.5.

A number of considerations must also be applied in regard to ratings. One of the most important is the amount of effort the user puts it into actual weight loss in regard to changes in diet, lifestyle, and exercise.

Among the most common comments left by users is that the product did cause an increase in energy, but also caused a pounding heart and “the jitters”. The stimulative effect of the Green Stinger ephedra pills lasted between two to three hours for most.

Conversely, some comments left by users claimed that it didn’t cause the shakes, and provided enough energy to get through a workout.

Others complained about feelings of nausea, but this also depends on the dosage and the milligram strength of the product. Nausea and upset stomach can be relieved by taking the pills with food and fluids.

The wide variety of reviews in regard to the efficacy of the product also factor in a person’s sensitivity to the components. Some individuals are sensitive to the stimulative properties of numerous ingredients found in Green Stinger ephedra, while others are not.

It is not designed as a long-term weight loss supplement, though for short term, some benefits have been noted.

One user claimed a drop of 30 pounds in approximately 6 weeks. A five-pound loss weight per week is certainly not recommended by medical or bariatric specialists, as it can cause an extreme loss in muscle tissue as well as other negative effects on the body.

Because of the wide variety of reactions, a number of users suggest that individuals cut the caplet in half, regardless of milligram strength, until their body adjusts to the surge of stimulants.

The reason individuals use products like Green Stinger ephedra may also differ in regard to results, such as using it as an appetite suppressant, as a thermogenic or stimulative supplement for fast weight loss, or those using it in combination with changes in lifestyle, diet and exercise to get started on a weight-loss program.

Where to Buy Green Stinger Ephedra

Green Stinger ephedra is available from a large number of online dietary and nutritional sports stores throughout the world. Sellers can also be found on Amazon and eBay, as well as other forums such as Alibaba.

Established online stores selling ephedra number into the dozens. Just a few include:

  • Ephedra Outlet – the store sells a variety of ephedra diet pills and products. Their Green Stinger is offered at $50 per bottle (120 capsules).
  • I-Supplements – containing 27 mg of ephedra, offers their product for $80, although it’s often on sale for approximately $50.
  • America’s Nutrition – average price: $50.
  • Ephedra Warehouse – sells ephedra products ranging from 10 mg to 50 mg and higher. Prices vary. Their Green Stinger ephedra averages $80, but it’s often found on sale for $50.

Green Stinger ephedra sold by Ephedra Warehouse ranks (by reviews) in the 90s for its appetite suppressant capabilities, and in the low 80s in regard to boost in energy or accelerated strength potential.

Schwartz Lab’s Green Stinger (27 mg ephedra) is among the more popular ephedra products on the market today. Schwartz Labs does provide a number of ephedra products in addition to the Green Stinger ephedra, including but not limited to:

  • Ultra-Burn (27 mg ephedra extract)
  • Blue Angel (ephedra metabolism booster containing 30 mg ephedra) – this product has lower ratings in regard to appetite suppression, energy, and strength as opposed to the Green Stinger ephedra in spite of its small increase in the ephedra milligram strength)
  • Lean and Hot Diet Pills, containing 27 mg ephedra

The average price per bottle of ephedra products by Schwartz Labs averages $40-$50, “on sale” which seems to occur quite frequently, with list prices of 100 caplets to 120 caplets averaging $80 per bottle.

Safety Considerations for Green Stinger Ephedra

Safety considerations for Green Stinger ephedra should always be factored into usage. Some studies have reported an increased risk of potential side effects and adverse cardiovascular events with the combination of synephrine and caffeine.

Of course, the dosage and frequency of dosage also comes into play. Some reports of myocardial infarction, hypertension, and cardiac arrhythmia have been noted in individuals consuming dietary supplements containing a combination of caffeine and synephrine and/or ephedra.

This includes the combination of those components with physical exercise. Therefore, it is cautioned that individuals not exceed “median intake from conventional foods.” [6]

It should be noted that synephrine is a form of sympathomimetic phenylethylamine is found in citrus fruits – again referring to the ‘adequate’ diet, which may prove even more beneficial in weight loss than turning to ephedra products.


The jury is out in regard to the true efficacy of an ephedra product that doesn’t contain the ephedrine alkaloids, which are the components responsible for increased metabolism, appetite suppressant capabilities, as well as thermogenic effects.

Consumers should be aware that if any seller offers an ephedra product that still contains ephedrine, it is likely relabeled, from a different country or expired, as such products have been found online and date prior to the ban of these products by the FDA in 2004.

Be aware that even products that don’t contain ephedra – and that substitute Bitter Orange – for similar effects, or even combine them, can have detrimental effects on the body, even at relatively low doses.

Any individual diagnosed with a medical issue should seek the advice of their physician prior to using any weight loss product or dietary supplement due to a number of potential and alarming side effects and contraindications against use.

While Green Stinger ephedra can, and does, promote some benefits of use and positive results for some users, it does also come with certain risks of potential side effects and adverse reactions.
