Updated August 10, 2023

If you've heard of ecdysterone, then you've probably heard of beta-ecdysterone.

These terms are often used interchangeably, especially in bodybuilding supplements.

But are they the same? What are the differences between them?

This article dives into the specifics of both beta-ecdysterone and ecdysterone, exploring their unique characteristics, benefits, and how they are utilized in various applications.

This article will breakdown the distinctions and similarities between these intriguing compounds.

Beta-Ecdysterone vs Ecdysterone

Beta-Ecdysterone, also known as 20-hydroxyecdysone, is a specific compound within the class of ecdysteroids and is known for its potent biological effects, including stimulating protein synthesis and promoting muscle growth.

On the other hand, Ecdysterone refers to the broader class of ecdysteroids, of which beta-ecdysterone is a member, and the specific effects can vary depending on the individual compound within this class.      

Ecdysterone: An Overview

Ecdysterone, or Ecdy, is a hormone found in arthropods, regulating their development.

Interestingly, it is also synthesized by several plants as a defense mechanism against insect pests.

Ecdysterone offers a range of beneficial pharmacological effects, including anabolic and adaptogenic properties.

It is widely marketed as a dietary supplement to enhance the physical performance of athletes.

In addition to its anabolic effect on muscle tissues, which depends on the estrogen receptor beta (ERbeta), Ecdysterone has been found to induce various other pharmacological effects.

However, the molecular mechanisms underlying these effects remain largely unknown.

The Role Of Ecdysterone In Fitness And Bodybuilding

Ecdysterone has been the subject of numerous studies due to its potential as a natural anabolic and adaptogenic compound.

It is often marketed to athletes as a "natural anabolic agent" in dietary supplements.

These supplements increase strength and muscle mass during resistance training, reduce fatigue, and aid recovery.

Several studies have demonstrated the anabolic effect of Ecdysterone and its beneficial effects for athletes.

This has led to Ecdysterone being considered as a potential performance-enhancing substance in anti-doping control.

The Science Behind Ecdysterone

Ecdysterone acts in insect nanomolar concentrations through ecdysone nuclear receptors (EcR).

However, humans do not have EcRs, and Ecdysterone does not interact with androgen or glucocorticoid receptors.

Despite this, Ecdysterone has been shown in vitro to stimulate ERbeta, which is involved in skeletal muscle hypertrophy.

Despite the reported anabolic properties of Ecdysterone, several studies have described Ecdysterone-induced sensitization of cancer cells to genotoxic drugs and reduction of tumors in mice.

This suggests that Ecdysterone may have potential applications beyond fitness and bodybuilding.

Ecdysterone And Beta-Ecdysterone: Are They The Same?

Ecdysterone and Beta-Ecdysterone are often used interchangeably in the fitness and bodybuilding industry.

However, while they are closely related, they are not identical. Beta-Ecdysterone is a specific form of Ecdysterone, much like how Vitamin D3 is a specific form of Vitamin D.

Ecdysterone and Beta-Ecdysterone are part of a class of compounds known as ecdysteroids, naturally occurring steroids.

They have similar properties and effects, but there may be slight differences in their biological activity due to their structural differences.

Beta-Ecdysterone vs Ecdysterone

Beta-Ecdysterone, also known as 20-hydroxyecdysone, is a naturally occurring ecdysteroid hormone that controls the molting and metamorphosis of arthropods.

It is the most active of the ecdysteroids, a group of steroid hormones similar in structure to androgens.

On the other hand, Ecdysterone is a broader term that refers to the class of ecdysteroids, of which beta-ecdysterone is a member.

Biological Activity

Beta-Ecdysterone has been shown to have a wide range of biological effects.

It has been found to stimulate protein synthesis, promote muscle growth, and enhance athletic performance.

It also has anti-inflammatory, antioxidant, and neuroprotective effects.

As a class of compounds, Ecdysterone shares these properties, but the specific effects can vary depending on the individual compound.


Beta-Ecdysterone can be found in various plants and insects.

It is most commonly extracted from the herb Leuzea carthamoides, also known as Maral root or Rhaponticum carthamoides.

Other sources include the herbs Suma (Pfaffia paniculata) and Cyanotis vaga.

Ecdysterone, being a broader class, can be found in a wider range of sources, including many species of insects, crustaceans, and plants.

Use In Supplements

Beta-Ecdysterone is often used in dietary supplements aimed at bodybuilders and athletes because it stimulates protein synthesis and promotes muscle growth.

It is considered a natural and safe alternative to anabolic steroids.

Ecdysterone supplements may contain a variety of ecdysteroids, but those containing beta-ecdysterone are generally considered the most effective.

Safety And Side Effects

Beta-Ecdysterone is generally considered safe and is not associated with the negative side effects often seen with anabolic steroids, such as liver damage and negative effects on mood and behavior.

However, as with any supplement, it should be used responsibly and under the guidance of a healthcare professional.

The safety and side effects of other ecdysterones can vary depending on the specific compound.

Research And Clinical Studies

Numerous studies have been conducted on the effects of beta-ecdysterone, many of which have shown promising results.

For example, a study published in "Archives of Pharmacal Research" found that beta-ecdysterone stimulates protein synthesis in skeletal muscle.

Another study published in "The FASEB Journal" found that it significantly increases rat muscle mass and endurance.

Research on other ecdysterones is ongoing, but beta-ecdysterone is this class's most well-studied and well-understood compound.

While beta-ecdysterone and ecdysterone are often used interchangeably in the context of dietary supplements, they are not exactly the same.

Beta-Ecdysterone is a specific compound within the class of ecdysteroids, and it is the most active and well-studied of these compounds.

Both have potential health and athletic performance benefits, but more research is needed to understand their effects and potential uses fully.

Ecdysterone: A Natural Performance Enhancer

Ecdysterone, a naturally occurring steroid hormone found in plants and insects, has been making waves in the fitness and bodybuilding communities due to its impressive benefits.

This plant-based compound, also known as 'Russian Secret,' has been linked to enhanced physical performance, muscle growth, and recovery, making it a sought-after supplement among athletes and fitness enthusiasts.

Research has shown that ecdysterone can significantly increase muscle mass with resistance training.

It works by increasing protein synthesis in the body, leading to faster muscle growth and repair.

Furthermore, ecdysterone has been found to reduce body fat and improve liver health, adding to its appeal as a performance-enhancing supplement.

Unlike synthetic anabolic steroids, ecdysterone is natural and non-hormonal, making it a safer alternative for those looking to boost their physical performance.

Ecdysterone And Bone Regeneration

One of the most significant benefits of ecdysterone is its potential to enhance bone regeneration.

A study found that β-ecdysterone could accelerate bone regeneration by enhancing the gene expression of the BMP-2/Smad/Runx2/Osterix signaling pathway.

This pathway plays a crucial role in the differentiation of osteoblasts, the cells responsible for bone formation.

The study also found that β-ecdysterone could upregulate the expression of osteoblastic-related genes, promote alkaline phosphatase (ALP) activity, and stimulate the formation of calcium nodules, all of which are critical processes in bone formation and regeneration.

Ecdysterone In Dietary Supplements

Ecdysterone is commonly found in dietary supplements, often marketed to athletes as a "natural anabolic agent." It's advertised to increase strength and muscle mass during resistance training, reduce fatigue, and ease recovery.

A study developed a method for identifying ecdysterone in dietary supplements and found that it was present in all tested supplements at estimated concentrations ranging between 5 mg/g and 383 mg/g.

This suggests that ecdysterone is a prevalent ingredient in many dietary supplements, likely due to its purported benefits for muscle growth and recovery.

Ecdysterone And Cognitive Function

Ecdysterone may also have potential benefits for cognitive function, particularly in the context of neurodegenerative diseases like Alzheimer's disease.

A study found that ecdysterone, in combination with high-intensity interval training (HIIT), could improve learning and memory abilities in a rat model of Alzheimer's disease.

The study suggested that this combination could be a promising potential therapeutic option against cognitive decline associated with Alzheimer's disease.

Ecdysterone And Fracture Healing

Ecdysterone might also play a role in fracture healing.

A study found that β-ecdysterone could facilitate fracture healing by activating autophagy, a cellular process that removes damaged components, suppressing the PI3K/AKT/mTOR signal pathway.

But how does β-ecdysterone do this? Well, scientists think it works by tweaking a set of instructions inside the cells.

This set of instructions, known as the PI3K/AKT/mTOR pathway, controls many important things like cell growth and survival.

So, β-ecdysterone might be a superpower for our bone-building cells, helping them work better and faster to heal damaged bones.

Side Effects And Interactions

While research on ecdysterone is ongoing, current studies suggest it is generally safe and well-tolerated.

In a study on mouse mesenchymal stem cells, beta-ecdysterone alleviated osteoporosis symptoms without any obvious side effects.

However, it's important to note that everyone's body reacts differently to supplements, and what works well for one person might not work well for another.

As with any supplement, starting with a lower dose is always a good idea to see how your body reacts and gradually increase the dose as needed.

It's also worth noting that while ecdysterone is generally considered safe, it hasn't been studied extensively in humans.

Therefore, potential long-term side effects are still unknown. Consulting with a healthcare professional before starting any new supplement regimen is recommended.

Who's It For

Ecdysterone supplements can benefit anyone looking to enhance their physical performance, build muscle, or improve their overall body composition.

This includes athletes, bodybuilders, and fitness enthusiasts.

However, it's not just for those involved in sports or physical activities.

Ecdysterone may also benefit those looking to improve their general health and well-being.

For instance, it has been found to have potential benefits in alleviating osteoporosis symptoms.

Who Should Avoid It

While ecdysterone is generally considered safe, certain individuals should avoid it.

This includes pregnant or breastfeeding women, as there is not enough reliable information about the safety of taking ecdysterone if you are pregnant or breastfeeding.

Additionally, individuals with hormone-sensitive conditions, such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids, should avoid ecdysterone as it might act like estrogen.
