SARMs vs Trenbolone – Which is more effective and Safer

  • By: Dave Moffat

In recent years, the use of performance-enhancing drugs (PEDs) has become increasingly common among bodybuilders and other athletes looking for that extra edge.

Statistics show that up to 54% of male bodybuilders have admitted to using steroids regularly, although this number is likely still too low due to under-reporting in top-level competition.

To replace steroids in the medical field, a newer form of PED known as SARMs has been developed. 

SARMs stand for selective androgen receptor modulators, which simply means they interact with certain receptors inside the body differently from steroids.

Unlike traditional anabolic steroids, SARMs bind with fewer receptors and cause fewer biological changes, theoretically resulting in fewer side effects.

However, SARMs still increase muscle protein synthesis and size when used correctly; therefore users must take caution when administering them.

Trenbolone is widely known as one of the strongest steroids available, with five times the potency of regular testosterone.

Unfortunately, it also comes with devastating side effects that keep many from taking this route for performance enhancement.

In comparison to Trenbolone, Selective Androgen Receptor Modulators (SARMs) offer a far safer option with fewer adverse effects making them an attractive choice for those looking for improved performance without sacrificing their well-being.

SARMs are often seen as “candy” in comparison to the ill effects of Trenbolone. People who want to improve their performance should think carefully about their options before deciding whether to take Trenbolone or SARMs.

SARMs vs Trenbolone

Trenbolone versus SARMs for Fat Loss

Fat loss is a challenge for many, but understanding how it works can help you make progress. When the body uses fatty acids for energy production, muscle mass can be preserved.

This process works because lipase, an enzyme present in the bloodstream, releases fat from fat cells into the bloodstream as free fatty acids (FFA).

These FFA’s can then be used as energy via a biochemical process known as beta-oxidation, part of what is called the Krebs cycle.

To get even better results with fat loss, people may consider using Trenbolone which is five times more powerful than regular testosterone and has a huge effect on body composition when combined with an appropriate diet and exercise plan.

While certain thermogenic compounds may have an impact on fat loss, trenbolone is the only pure steroid that can trigger serious weight loss.

SARMs, however, is not exactly a single compound; rather, they are comprised of several types and examples which work differently to produce desired effects.

Of all the SARMs available, Cardarine is the only one that causes fat loss as it increases Beta Oxidation thanks to its ability to deregulate carbohydrate metabolism.

Additionally, Trenbolone has proven more potent than SARMS when it comes to producing a lean and dry look.

SARMs vs Trenbolone for Gaining Muscle

When it comes to hypertrophy or the act of our bodies producing muscle from food, there is a great deal of focus on diet, training, and drug choice.

SARMs and Trenbolone both have their uses when attempting to increase lean muscle mass, however, there are important distinctions in terms of their efficacy: Trenbolone is another order of magnitude more potent than SARMS.

Unfortunately, this heightened potency comes with an additional risk that of potentially damaging one’s health by the use of Trenbolone.

It is therefore essential that individuals take caution and talk to medical professionals before considering its use as a means to build muscle.

Is Trenbolone a SARM?

Trenbolone is an androgenic anabolic steroid with a 19-Nor Testosterone composition that was designed to serve as an alternative to steroids in the medical world.

It yields superior results compared to SARMs but, unfortunately, also brings about a higher propensity for associated health risks.

While Trenbolone may give better results than SARMs and traditional steroids, users should weigh the pros and cons before considering this substance.

The properties of Trenbolone allow it to be extremely effective for muscle-building activities, yet the potential side effects make it essential to closely monitor usage levels and safety protocols.

As a result, if individuals decide they would like to experiment with Trenbolone, they need to ensure they are well aware of all the risks associated before beginning their cycle.

Do SARMs have the same effect as steroids?

SARMs, short for Selective Androgen Receptor Modulators, has been a rapidly growing trend in the bodybuilding scene over the past few decades.

This is mainly due to their promise of similar results as steroids without harsh side effects.

While it is true that SARMs do not match the efficacy of steroids in terms of building muscle mass, they do offer a viable alternative which has become more important given how more cautious bodybuilders are becoming when it comes to their health.

It is commonly thought that SARMs are predominantly going to be used by newcomers and women who want to minimize their risk profile while still seeing some gains in muscle growth.

Although SARMS will never work as well as Steroids, they should remain an attractive option, particularly for those just starting with developing their physique.

SARM Examples and Comparisons to Trenbolone


Trenbolone is a powerful anabolic steroid that offers an array of advantages. It is going to be very effective for fat loss; far more than any other SARM.

In addition, it can dramatically stimulate muscle growth, as well as significantly increase strength and aggression. However, it also has the potential to drastically reduce endurance levels due to its influence on overall health.

Generally speaking, dosing for Trenbolone ranges from 75 – 400mg per week; however, it is important to note that purchasing steroids such as this one is illegal in most countries and thus should be avoided.

LGD 4033

LGD 4033, also known as Ligandrol, and Trenbolone are two powerful compounds used by those looking to build muscle mass.

It is well established that Trenbolone will lead to greater fat loss compared to Ligandrol, and on top of that provide more muscle development than any SARM currently available.

While there is a huge benefit in using either of these substances, be aware that it can also impact your endurance training negatively neither will provide a beneficial effect on your ability to go the extra mile.

To ensure safety, only purchase SARMs at dosage concentrations between 10-20mg as research chemicals.


Cardarine can prove to be a beneficial tool for those looking to burn fat, as studies have suggested that it has the potential for better fat-burning results than Trenbolone.

Yet unfortunately, Cardarine does not fare well when it comes to building muscle mass; Trenbolone appears to be substantially more effective in this area than any of the SARMs currently available on the market.

However, performance-wise, the two supplements differ greatly; Cardarine has positive effects on endurance while Trenbolone brings with it a set of consequences regarding fatigue, making it difficult to exercise over long periods and thus weakening strength capabilities.


Both Ostarine and Trenbolone are poor options when it comes to fat loss, but there is a difference between the two.

While Ostarine will not help you with fat loss, it is a less potent substance than Trenbolone when it comes to muscle and strength building.

In comparison to other SARMs on the market, Trenbolone is far superior when it comes to muscle building and increasing strength.

However, one should be aware that neither Ostarine nor Trenbolone will benefit one’s endurance in any way; both substances could even have an effect of reducing endurance capabilities.

MK 677

People looking to use either MK 677 or Trenbolone for fitness goals should be aware that each of these compounds carries different benefits.

MK 677 is not as effective for building muscle as Trenbolone, but it could potentially promote more fat loss. Additionally, MK 677 might also have a positive effect on endurance if used correctly.

Comparatively, Trenbolone can deliver more strength-building results than any SARM currently available.

Although the decision depends largely on what your individual goals are, understanding the qualitative differences between these two substances is important in making an informed choice.

YK 11

The strength-building capabilities of YK 11, the strongest SARM available, are unparalleled, but Trenbolone will still build more muscle.

Comparing SARM to anabolic steroids is futile Trenbolone is superior in terms of building strength and there isn’t any SARM on the market that can match its properties in that area.

That said, neither YK 11 nor Trenbolone will do anything for improving endurance; more likely, using either one could result in a decrease.

Athletes need to understand this and err on the side of caution when incorporating SARMs or anabolic steroids into their training program.


To sum up, when it comes to fat loss and muscle building, Trenbolone seems to have an edge over Andarine.

While neither will provide much assistance in improving endurance, Trenbolone is the clear winner when it comes to its strength-building capabilities.

This certainly makes sense as this particular steroid has been used for years by bodybuilders looking to increase their muscular gains.

In contrast, Andarine, while sometimes beneficial for fat loss and muscle growth, just cannot compete with its counterpart but can still be a useful supplement depending on individual goals.

RAD 140

Despite having fat loss advantages, RAD 140 is limited in this regard when compared to Trenbolone, which releases much higher levels of hormones that enable more intense lipolysis and oxidation.

When it comes to lean muscle mass, Trenbolone will outcompete RAD 140 any day; the former has been shown in studies to be the most anabolic of all commonly used anabolics on the market.

Strength-wise too, Trenbolone has far superior performance potential than RAD 140 or any other SARM, as its ability to produce larger amounts of hormones translates directly into enhanced muscle strength and power output.

Nevertheless, neither RAD 140 nor Trenbolone is effective for endurance; in fact, both have been linked with reduced physical endurance due to unfavorable hormone balance alterations.

What makes anabolic steroids different from SARMs?

Although both anabolic steroids and SARMs mimic the effects of testosterone in the body, they do so differently.

While steroids are hormones that carry a greater risk for side effects since their chemical composition is similar to the hormone produced by our bodies, SARMs are much milder and thought to be safer alternatives.

They are designed to interact with specific cell receptors unlike steroids, but ironically, this also makes them weaker than traditional steroids.

Potential SARMs side effects

  • Decrease in natural testosterone production, although typically to a lesser degree than with anabolic steroids.
  • A strain on the liver due to increased enzyme activity. It is generally recommended to cycle SARMs and avoid taking them for extended periods if liver health is a concern.
  • An increase in cholesterol levels, although some SARMs may support cholesterol management.
  • Hair loss is not known to occur directly as a result of taking SARMs but can be caused indirectly through hormonal imbalances related to their use.
  • Abuse of SARMs could lead to kidney damage, and trenbolone specifically has been linked with renal failure. 
  • Estrogen levels can increase when taking certain SARMs, potentially leading to gynecomastia in men. 
  • Acne outbreaks are not uncommon among those who take such compounds due to increased sebum production. 
  • Erectile dysfunction has been reported by some users, often as a result of hormonal imbalances brought about by SARMs usage.

Potential Trenbolone side effects

• Increase in libido, which can be too much for some people to handle.

• Increase in estrogen levels which is a known side effect of Trenbolone use and can lead to gynecomastia (development of enlargement of breast tissue in men) and water retention.

• Serious strain on the kidneys due to increased Prolactin levels; this could lead to potential kidney damage over time.

• Hair loss has been found to occur during Trenbolone use due to its hormonal impact on the body, leading to follicle sensitivity.

• Cholesterol levels can become severely impacted with Trenbolone use as it acts as an antagonist by increasing LDL cholesterol while decreasing HDL cholesterol, both of which are linked to heart health problems.

• Place a strain on the liver greater than that of SARMs (selective androgen receptor modulators). The hepatotoxic effects of Trenbolone may be further heightened if taken orally instead of via injection, potentially leading to serious liver damage over time. 

• Downregulation of Testosterone production due to interference with natural hormone pathways; this means that once usage is stopped, there may be a period where testosterone levels remain low and recovery is impaired until natural production resumes.

SARMs are an attractive option for those looking to achieve the body-building benefits of anabolic steroids like Trenbolone, without the adverse side effects.

Trenbolone is a very potent steroid known for its powerful muscle-building properties, yet comes with significant risk when used in higher doses and short cycles.

In comparison, some research studies have found that SARMs deliver noticeably positive results similar to those achievable using anabolic steroids while avoiding the adverse side effects associated with extended use of such compounds.

Unfortunately, both SARMs and Trenbolone have been banned by major sporting competitions; however, SARMs can still be used in research studies where efficacy and safety can be further documented.
