Trenbolone Side Effects

11 Severe Trenbolone Side Effects | What To Expect On Tren 1
Trenbolone is a versatile steroid used for bulking, cutting, strength and conditioning. It promotes muscle growth by increasing nitrogen retention and red blood cell production. Learn more.

Trenbolone side effects, when used by humans, can occur. Trenbolone has a reputation for being one of the strongest anabolic-androgenic steroids used by bodybuilders, although it is not a drug meant for human use.

As a veterinary-grade steroid, Trenbolone (made from Finaplix pellets) is intended to increase feed efficiency in heifers and steers prior to slaughter.

When bodybuilders translate the benefits of Trenbolone use in animals to human use, they must also, therefore, expect the potential for the same, or worse, side effects in the human body. Click here to visit our recommended supplier.

Is Trenbolone Safe For Human?

Is Tren Safe

Trenbolone is not designed for use in humans and is not used by reputable doctors domestically or abroad for medical treatments.

The risk of Trenbolone side effects has not been specifically researched on humans, but why should it be? It’s for animals.

Two of the most commonly used forms of Trenbolone by bodybuilders have slightly different molecular formulas:

Another form of Trenbolone (Trenbolone acetate and estradiol) is marketed under the brand names Synovex and valor.

Trenbolone and estradiol were approved for veterinary use in 2007, offering a slow-release delivery system designed to improve weight gain and feed efficiency in confined steers for up to 200 days prior to slaughter.

According to the manufacturer, one implant (comprised of 10 pellets), contains 200 mg Trenbolone acetate combined with 40 mg estradiol. Every single pellet contains 20 mg Trenbolone acetate and 4 mg estradiol.

In cattle, weight gain and feed efficiency (digestion, metabolism, and nutritional benefits) were increased.

Veterinary-grade steroids like Finaplix, Revalor, and Synovex clearly state on package labels statements that the drug is designed for animal treatments only. Not for human use.

Why Do Bodybuilders Use Trenbolone?

Trenbolone Results In Bodybuilding

Trenbolone (Trenbolone acetate and Trenbolone enanthate) contains extremely potent anabolic characteristics, but also extremely potent androgenic properties.

Trenbolone acetate is basically known as a growth promoter in the veterinary world, and the same applies to supposed effects regarding human usage.

Concerns regarding safety are often ignored by bodybuilders and athletes because of the benefits in muscle mass gains, lean physique, and increased metabolism and its equated “feed efficiency”.

Trenbolone acetate is often preferred in the development of lean muscle mass and strength increase, along with reduced risk for estrogenic effects such as bloating or water retention.

Because of its anabolic properties, it is popular among bodybuilders preparing for competition in producing a “hard” physique.

Trenbolone acetate is often combined with other drugs in the bulking or muscle mass development cycle or phase due to its inability to promote such development on its own.

However, its versatility also makes it effective in cutting or dieting phases due to its ability to encourage fat loss while at the same time encouraging the development of new muscle growth.

In such phases, it’s often combined with another veterinary grade steroid (Equipoise) as well as various forms of synthetic testosterone such as Dianabol.

What To Expect On Tren

What To Expect On Tren

Because of its strong anabolic and androgenic properties, Trenbolone side effects are not only possible but probable.

Because of this, bodybuilders often stack Trenbolone with a variety of anti-estrogenic and anti-androgenic drugs, with varying degrees of success.

Trenbolone side effects can be minor and temporary such as the development of acne, headaches, and increased growth of facial and body hair. Women will notice more virilizing (masculinization) side effects than men.

One of the most feared side effects when it comes to Trenbolone is the potential for gynecomastia.

Trenbolone is a non-aromatizing steroid (involvement in the conversion of testosterone to estrogen) although it does have a tendency to bind to progesterone receptors, which are similar to estrogen.

This activity inhibits the production of testosterone and increases fat storage as well as stimulates estrogens, which contribute to gynecomastia.

In spite of efforts by bodybuilders to effectively reduce or even negate Trenbolone side effects, they do occur, and often with surprising results.

Tren Side Effects

Combining steroids and other drugs to balance hormone levels can contribute to numerous side effects or adverse reactions as well as potential damage to numerous body systems that include the endocrine (hormone) system, metabolism functions, and cardiovascular, kidney, and liver function.

A variety of studies have been performed on the effect of Trenbolone and its side effects on animals other than cattle. Some show alarming results.

A few of these studies show obvious benefits in regard to musculoskeletal behaviors, but adverse reactions are also prevalent.

One of the most negative aspects of Trenbolone use is its ability to contribute to catabolism in bone and muscle.

Because of this potential for Trenbolone side effects, bodybuilders often combine Trenbolone with selective androgen receptor modulators or SARMs – again with varied results.

Anabolic steroids have been linked to severe and long-lasting organ damage including hepatotoxicity, cardiomyopathy, and other damaging heart conditions such as ventricular arrhythmias, just to name a few.

Trenbolone side effects are real and should be carefully weighed against benefits prior to use.
