About Finaject – Functions

Finaject or Trenbolone Acetate is the fast-acting variant of Trenbolone. It is classified as a 19-nortestosterone or 19-nor anabolic steroid. It comprises the Trenbolone hormone attached to the short Acetate ester. The user needs to perform multiple injections a week to maintain stable blood levels.

Trenbolone falls in the same category as Nandrolone. In fact, this steroid is just an altered Nandrolone hormone. It is a Nandrolone hormone with an added double bond at carbon positions 9 and 11. This makes Trenbolone more androgenic than Nandrolone. It significantly increases the hormone’s binding affinity to the androgen receptor. What’s more, it prevents Trenbolone from aromatizing. The conversion of testosterone to estrogen is known as aromatization. Anabolic steroids that aromatize can cause estrogenic side effects such as water retention, high blood pressure, gynecomastia, etc. Since Finaject or Trenbolone Acetate doesn’t convert into estrogen, you don’t need to be worried about these things.

It is a popular anabolic steroid among athletes due to the traits it carries. Though it is a Vet grade steroid, it has held huge success in the human pharmaceutical market at one time. Parabolan, a popular Tren compound, was used in medicines for a long time. The difference between Parabolan and Finaject is the ester that is attached. When the Trenbolone hormone is attached to the Acetate ester, we call it Finaject. And when the hormone is attached to the Hexahydrobenzylcarbonate hormone, we call it Parabolan.

The most common and primary traits of Trenbolone Acetate include:

  • Trenbolone Acetate increases the production of red blood cells in the body. Red blood cells are cells that carry oxygen through the blood. An increase in red blood cell count in the body increases overall muscular endurance. This allows the user to do his regular training for a longer period of time.

  • This steroid will increase nitrogen retention within muscles. It also enhances protein synthesis. Protein synthesis is basically the rate by which proteins are built. When protein synthesis increases, more proteins are available for work and production. It greatly contributes to promoting the body’s anabolic atmosphere. It also improves the recovery rate. It is essential during both the bulking and cutting phases. Increased nitrogen retention also helps us remain anabolic. Lean muscle tissues in the body comprise almost 16% nitrogen. An increase in nitrogen retention also helps the user enjoy improved recovery times and progress.

  • This anabolic steroid increases IGF-1 production and reduces glucocorticoids in the body. IGF-1 or Insulin-Like Growth Factor-1 is a protein hormone of the peptide class that plays an essential role with HGH in a regulation sense. IGF-1 is also crucial to the ability of the body to rejuvenate. An increase in IGF-1 output increases the healing rate and improves recovery times. Glucocorticoids are basically muscle wasting and fat promoting hormones. These hormones are essential to the immune system. However, they can become obstacles for performance-enhancing athletes when found in abundance. Finaject helps keep glucocorticoid hormone levels to a minimum state. It will help you remain anabolic.

  • Finaject also increases feed or nutrient efficiency. This is a trait that makes this compound one of the greatest anabolic steroids ever. It will make every nutrient that you will consume more valuable. The body usually uses each nutrient only to a certain degree. But with Finaject, the body will be able to better use every nutrient, be it fat, protein, or carbohydrate. It means you will make more progress with the same total calorie intake. It is actually the main reason why this compound is given to livestock before slaughter.

A cutting phase is the best time to use this steroid. Finaject will help you maintain lean tissue when dieting. Users can use it for conditioning. You can expect to attain a well-defined physique by administering this steroid. However, the effects will be noticeable only in those who are already lean. The Trenbolone hormone works by increasing the metabolic rate of the body. It promotes fat loss. However, this steroid alone won’t make you lean. You must do regular workouts and maintain a proper diet in order to achieve optimal results.

You can also use Finaject during a bulking phase. This steroid can help you gain muscle mass. The best thing is that this steroid doesn’t aromatize. This means all weight gained as a result of Finaject use will be lean tissue. It will also significantly boost your strength.

Finaject Administration

You can perform Finaject injections intramuscularly. It means you can inject it into any muscle on your body. The standard dosage of Finaject is 50-100 mg every other day. Many experienced and advanced steroid users also use more than 100 mg of Finaject every other day. Many users administer 600-700 mg of Finaject per week.

1. Estrogenic Side Effects

Finaject is one of the anabolic steroids that do not aromatize. Thus, estrogenic side effects are impossible with this steroid. It means the users won’t experience water retention or gynecomastia. However, Trenbolone is a progestin. Thus, sensitive men may experience gynecomastia or the enlargement of breasts. You can consider using an aromatase inhibitor or AI to deal with this issue.

2. Androgenic Side Effects

Finaject can cause many androgenic side effects that include hair loss, acne, body hair growth, etc. Administering Tren can accelerate hair loss in men who are predisposed to male pattern baldness. Acne is experienced by men who are sensitive to acne.

Finaject can cause virilization symptoms in women. These include a deepening of the voice, clitoral enlargement, etc. Finaject is not an ideal steroid for female use.

3. Testosterone Suppression

Finaject will suppress natural testosterone production in the body. In fact, the suppression of testosterone production can be significant. The body will experience a low Testosterone condition if used without exogenous Testosterone. That’s why you are advised to take exogenous Testosterone when using Finaject.

Once use is discontinued, natural testosterone production will begin again. However, complete recovery can take several months. This is the reason why the users are advised to implement a PCT plan. A solid PCT plan will significantly speed up the recovery.

Studies On Trenbolone Acetate

Here are a few studies on the effects of Trenbolone Acetate that will help you know how effective Finaject or Trenbolone Acetate can be:

1. Effects of Trenbolone Acetate and Testosterone on Growth and on Plasma Concentrations of Corticosterone and ACTH in Rats

This study ( examines the effects of Trenbolone Acetate on growth and plasma concentrations of corticosterone in make and female rats. Rats were injected with Trenbolone Acetate daily for 10 days. This compound caused an increase in weight gain, a reduction in plasma concentrations of corticosterone, and a reduction in adrenal weight in female rats. On the other hand, Trenbolone Acetate caused no significant changes in these parameters in male rats. The response is compared with that of testosterone. Female rats were injected with the oil vehicle, Trenbolone Acetate, or Testosterone Propionate on a daily basis. Testosterone increased weight gain. A reduction in plasma concentrations of corticosterone is observed in response to TBA. Testosterone plasma concentrations of corticosterone. The study concluded that part of the anabolic activity of Trenbolone Acetate may be related to a reduction in circulating concentrations of corticosterone.

2. Effect of Trenbolone Acetate on Protein Synthesis and Degradation Rates in Fused Bovine Satellite Cell Cultures

And it won’t be affected by genetics. Due to this reason, users are advised to include exogenous testosterone in their plan. Failing to use exogenous testosterone can result in a low testosterone condition. Low testosterone levels in the body can cause several symptoms, including erectile dysfunction, suppressed libido, etc. Once you discontinue the use of steroids, the production of natural testosterone will begin again. However, it may take several weeks or months to get the testosterone level restored back to normal. You may lose muscle mass and strength during the period. Cortisol can also become dominant during this phase. That’s why it’s advisable that you implement a PCT plan once the use of steroids comes to an end. It will reduce the recovery time by stimulating natural testosterone production. A proper PCT plan can ensure that there is enough testosterone for the body to carry out its functions.

3. Cardiovascular

Parabolan can affect cardiovascular health by increasing LDL cholesterol and suppressing HDL cholesterol. It can also lead to high blood pressure. This makes it important to lead a cholesterol-friendly lifestyle. Make sure that you include foods that are rich in omega 3 fatty acids in your diet plan. Also, do workouts regularly to stay fit.

4. Natural Testosterone Suppression

Trenbolone Hexahydrobenzylcarbonate will suppress natural testosterone production in the body. And the suppression rate will be extreme. So, it’s important that you include exogenous testosterone in your plan. If you do not include exogenous testosterone in your plan, you will be left with a low testosterone state. This comes with several bothersome symptoms and can affect your physical, mental, and sexual health. You need to know that a low testosterone condition is extremely unhealthy.

The production of natural testosterone will begin automatically once you discontinue the use of the steroid. However, the process will be slow. That’s why users are advised to run a PCT or Post-Cycle-Therapy. PCT medications will improve recovery time. It can ensure that you have adequate testosterone in your body for bodily functions during the recovery phase.

It’s better to discontinue use if you experience any of these side effects. These side effects will fade away within a few days after discontinuation.

If you are a beginner looking to get started with the Trenbolone hormone, then it’s better to use Trenbolone Acetate. This is because of the adverse effects that this compound causes.

Parabolan Administration

It’s important to follow the dosage and usage instructions to get the most out of this compound. Parabolan is an anabolic steroid with a concentrated strength that is a bit unique. A single ampule carries 76mg per milliliter. It gives 50 mg of active Trenbolone. The standard dosage of Parabolan for performance enhancement purposes is 3-4 ampules per week. This Parabolan dose should be enough to get significant results. Advanced users may consider administering higher doses (5-6 ampules a week). However, you need to keep in mind that higher doses increase the risk of adverse effects associated with use.

The standard duration of use is usually 8-10 weeks. This doesn’t represent the total cycle of anabolic steroids. It just represents the Parabolan part of the plan. Parabolan can be used in combination with other anabolic steroids. During a cutting phase, you can consider stacking Parabolan with Masteron, Winstrol, and Testosterone. On the other hand, you can combine Parabolan with Anadrol or Dianabol in a bulking cycle.


So, all three versions of Trenbolone are extremely powerful and can help you achieve your bodybuilding and performance goals when used responsibly.
