Description

What is Parabolan?

Parabolan is a brand name for the anabolic-androgenic steroid (AAS) trenbolone hexahydrobenzylcarbonate (or trenbolone cyclohexylmethylcarbonate). It is a synthetic derivative of the hormone nandrolone. Trenbolone was originally developed for veterinary use to increase muscle growth and appetite in livestock. It is not approved for human use in most countries.

Side Effects and Benefits

Benefits:

  • Increased muscle mass and strength: Trenbolone is known for its potent anabolic effects, which lead to significant gains in muscle size and strength.

  • Fat loss: It is believed to help with fat loss, making it popular for bodybuilding cycles focused on "cutting" or creating a lean physique.

  • Does not aromatize: Unlike some other anabolic steroids, trenbolone does not convert to estrogen in the body. This reduces the risk of estrogen-related side effects like gynecomastia (enlargement of breast tissue in males) and water retention.

Side Effects:

The side effects of Parabolan can be severe and may be permanent. They vary depending on dosage, duration of use, and individual factors.

  • Androgenic side effects: These are common due to the steroid's high androgenic rating. They can include severe acne, oily skin, accelerated male pattern baldness, and increased body and facial hair growth.

  • Cardiovascular issues: Use can lead to hypertension (high blood pressure) and an increased risk of heart attack.

  • Hepatotoxicity and kidney stress: Trenbolone can be toxic to the liver and cause stress and potential damage to the kidneys.

  • Psychological and neurological effects: This is a major concern with trenbolone, often referred to as "tren rage." Side effects can include extreme mood swings, aggression, anxiety, depression, and sleep disturbances (insomnia).

  • Reproductive system: Trenbolone strongly suppresses the body's natural production of testosterone, which is crucial for sperm production and overall fertility. It can lead to infertility and testicular atrophy.

  • Other side effects: Users may experience a "tren cough" immediately after injection, night sweats, and reduced insulin sensitivity.

Pros and Cons

Pros:

  • High anabolic potency, leading to significant muscle and strength gains.

  • Does not convert to estrogen, avoiding related side effects.

Cons:

  • Serious and potentially irreversible side effects, including cardiovascular, liver, and kidney damage.

  • Severe psychological and neurological side effects.

  • Strong suppression of natural testosterone production.

  • Illegal for non-medical use in many countries.

  • Lack of clinical data on its safety profile in humans, as it is not approved for human use.

Dosage and Frequency

Information regarding dosage and frequency is often found in the context of illicit use and is not medically sanctioned. Typical dosages for men range from 152–220 mg per week for beginners to 228–456 mg or more per week for more experienced users. The frequency of injections is often based on the half-life of the ester.

Half-Life and Detection Time

  • Half-life: The elimination half-life of trenbolone hexahydrobenzylcarbonate is approximately 8 days. This is longer than other trenbolone esters like trenbolone acetate (1-2 days).

  • Detection time: The detection time in urine for trenbolone and its metabolites is generally long, often cited as 4-5 weeks. However, detection times can vary significantly based on the specific test, dosage, duration of use, and individual metabolism.

Steroidogenic, Progestogenic, and Prolactin Effects

  • Steroidogenic: Trenbolone is a synthetic anabolic steroid. It works by binding to and activating androgen receptors, which are responsible for its anabolic and androgenic effects. It also has a powerful effect on protein synthesis and nitrogen retention.

  • Progestogenic: Trenbolone has a strong progestogenic activity. This means it can bind to progesterone receptors in the body. Progestogenic activity can be a factor in some side effects, especially in combination with estrogen.

  • Prolactin: Due to its progestogenic nature, trenbolone can indirectly lead to an increase in prolactin levels. Elevated prolactin can cause side effects such as gynecomastia (even without elevated estrogen) and lactation in men. This is why some users may combine it with a prolactin-inhibiting drug.

Anabolic-Androgenic Ratio

The anabolic-androgenic ratio of trenbolone is often cited as being 500:500. This is a highly simplified comparison to testosterone, which has a ratio of 100:100. This number indicates that trenbolone is considered five times more potent than testosterone in both its anabolic (muscle-building) and androgenic (masculinizing) effects.
