Buy Trenbolone online in USA, where to buy real steroids

Trenbolone is an extremely powerful synthetic steroid that bodybuilders and athletes use to rapidly build significant muscle mass and strength. However, there is a lot of confusion around whether trenbolone is technically a steroid or not. This comprehensive article examines the question – is tren a steroid? We’ll analyze the chemical structure, effects, risks and legal status of trenbolone.

What is Trenbolone?

Trenbolone is a potent synthetic androgen that belongs to the 19-nortestosterone class of anabolic-androgenic steroids (AAS). It was originally developed as a veterinary drug to increase muscle growth and appetite in cattle.

Trenbolone does not occur naturally in the body and is not derived from testosterone like many other AAS. It is a modified form of the hormone nandrolone. Trenbolone has an anabolic (muscle-building) rating of 500 and androgenic (masculinizing) rating of 500.

This makes tren far more myotropic (muscle-building) and androgenic than testosterone, which has a rating of 100 in both categories. Today, trenbolone acetate is used illicitly by athletes and bodybuilders at dosages 5-10 times higher than the recommended veterinary dosage.

Is Trenbolone a Steroid?

Is Trenbolone a Steroid?

Despite some confusion and debate, trenbolone is categorized as an anabolic androgenic steroid (or anabolic steroid). This is because trenbolone meets the two key criteria that define a steroid:

It is a synthetic substance derived from androgenic hormones
It promotes the growth of skeletal muscle and masculinizing effects similar to testosterone

Even though trenbolone is not directly derived from testosterone, it is structurally analogous to nandrolone, which is derived from testosterone. Tren powerfully binds to androgen receptors on muscle cells to exert potent anabolic effects.

Due to its non-testosterone structure, some argue trenbolone doesn’t qualify as a “true steroid”. However, since it behaves pharmacologically like a steroid and meets the functional definition, trenbolone is classified by experts as a potent anabolic-androgenic steroid.

How Does Trenbolone Work?

How Does Trenbolone Work?

Trenbolone promotes rapid muscle growth through several key mechanisms:

It powerfully binds to androgen receptors on muscle cells, sending strong signals to build muscle proteins and tissues.

It increases nitrogen retention in muscle fibers, creating a positive nitrogen balance that enables rapid muscle growth.

It boosts protein synthesis rates and inhibits muscle breakdown during and after exercise.

It raises red blood cell production, increasing oxygen delivery and muscle endurance.

It allows muscles to hold more glycogen, fueling intense workouts.

Additionally, trenbolone increases nutrient efficiency so every calorie and gram of protein builds more muscle. It also has potent fat-burning effects, helping bodybuilders get leaner.

These anabolic and androgenic effects are exponentially more powerful than natural testosterone production. This enables incredible gains in muscle mass and strength over short periods.

Side Effects and Health Risks

While trenbolone enables bodybuilders to gain rock-hard, ripped muscle, it carries significant side effects:

Increased blood pressure and cholesterol levels
Liver toxicity and damage
Excess estrogen conversion causing gynecomastia
Low natural testosterone production
Erectile dysfunction, low libido
Acne, oily skin, hair loss
Aggression, anxiety, insomnia, night sweats

Since trenbolone cannot aromatize into estrogen, it does not cause water retention. However, it is highly suppressive to natural testosterone production. Most bodybuilders run trenbolone with testosterone-based steroids to offset low T effects.

Cycling on and off tren reduces side effects. But all trenbolone use carries serious health risks given its toxicity and androgenic effects even at low doses.

In summary, despite some chemical differences from traditional testosterone-based steroids, trenbolone exhibits all the properties, effects and risks of an extremely potent anabolic-androgenic steroid. All credible experts and regulatory agencies unequivocally classify tren as a potent steroid.

While offering rapid muscle and strength gains, trenbolone carries significant health and legal risks. Responsible use under medical supervision is crucial to minimize side effects. But all non-prescription trenbolone use remains legally prohibited in most countries.
