What is trenbolone
Trenbolone is an androgenic and anabolic steroid that comes in the form of esterified derivatives. The drug is sold under several brand names and may be known to users as Parabolan, Finaplex, Tren, and Finadget. The steroid was originally used to increase muscle mass and appetite of livestock in veterinary medicine.
Acetate is the most common form of trenbolone. This ester is characterized by a minimal duration of action that is deposited in fat depots. The active substance begins to enter the bloodstream, evenly divided. The high injection frequency is due to the short half-life, which may not be suitable for beginners. Acetate should be administered 50 to 100 mg every other day.
Cyclohexyl methyl carbonate is a rare form of this steroid. The situation is made worse by the large number of counterfeits, but the original form can be found. It is produced, for example, by Balkan Pharmaceuticals in Moldova. Trenbolone hexahydrobenzyl carbonate is injected 300 mg every seven days.
The enanthate has similar pharmacological characteristics to cyclohexylmethylcarbonate. The duration of action is 10 days. The injection volume is 300 mg once or twice a week.
Trenbolone is available in three main forms under different brand names. It is not consumed in its original form, but only the following derivatives are used:
Trenbolone acetate is the most common form of the drug, but its effect is very short-lived, so daily injections of 50 mg are needed. Trade names. This is an acetate that is highly sought after by bodybuilders.
Trenbolone Enanthate is a longer lasting anabolic steroid that lasts about 10 days. The optimal dosage is 300 mg per week. You can take it all at once or split it into two injections.
Trenbolone Trenbolone hexahydrobenzyl carbonate or cyclohexyl methyl carbonate is available under the brand name Parabolan. The duration of action and dosage are the same as the previous form of the drug.

Chemical structure
Trenbolone enanthate is an anabolic steroid dissolved in oil with the enanthate ester incorporating a 17-beta-hydroxyl group which delays the release of trenbolone from the injection site much more compared to the acetate version of this steroid (17b-9 -trien-3-one), the formula of the ester being C7H14O2. Its half-life in the body is approximately 6 to 8 days (15 to 16 days). Trenbolone is a modified version of nandrolone. The difference is in the introduction of a double bond between carbohydrates 9 and 11, which prevents aromatization, e.g., nandrolone is weakly aromatized, although it produces small amounts of estrogen, which is not characteristic of trenbolone. The 11-12 bond further increases its binding to the androgen receptor. Trenbolone is non-estrogenic, more anabolic and androgenic than nandrolone. It is more similar to drostanolone than to nandrolone. It is three times more androgenic than testosterone, making it one of the most potent steroids.
When calculating the dosage, it should be kept in mind that 100 mg of testosterone enanthate contains significantly less of the base hormone than 100 mg of testosterone solution (suspension). In this case, the content of the hormone is 72 mg, and the remaining 28 mg is the mass of the enanthate ester. Trenbolone enanthate is very similar in its action to trenbolone hexahydrobenzyl carbonate and provides an increase in muscle mass while improving its penetration.

Purpose and effects of trenbolone
Like all AAS (androgenic anabolic steroids), this product is based on modified testosterone, a male sex hormone that plays an important role in muscle growth and bone strength. One of the most important features of each of the above forms of trenbolone is the lack of aromatization – i.e. the anabolic conversion of estrogen. This prevents the development of secondary signs (gynecomastia in men).
This AAS is used to gain muscle mass and lean muscle mass. In addition to all this, it also has the following effects:
Significant increase in strength and muscle mass (on average by 10 kg in one course).
It does not retain fluids in the body, which has a positive effect on muscle definition.
Fast results. A significant increase in strength is observed after the first dose.
It has an anti-catabolic effect, as it retains nitrogen in the body, which makes up about 16% of muscle tissue.
It increases endurance by increasing the number of red blood cells in the blood.
Fat burning. So trenbolone is very good on the ground.
Reducing cortisol (stress hormone) levels.
This steroid course is contraindicated for women and beginners. If you are a fearless athlete who is not afraid of all these horrors in the form of possible side effects, then you should follow a few rules and choose a competent course. In any case, you should not exceed the dosage as much as you would like. The recommended dosages are described in the section above which describes the types of drugs.
It is advisable to use the gradual dose increase method, where the lowest dose of steroid is given first, and then gradually increased to the optimal dose. This will allow you to identify the side effects of that steroid or individual intolerances with minimal damage to your health.
A course should not last more than 6 weeks. A specific diet to increase muscle mass will not be superfluous to achieve better results. After two weeks of use, start combining trenbolone with gonadotropin if you do not want to lose fertility. Gonadotropin – once a week, 500-1000 IU. Discontinue taking two weeks after last injection with Tren. After 2-3 days from the last acetate injection (if other varieties of trenbolone were used, then after about 2-3 weeks), post-course treatment is required.

Combination course
If your goal is not only to gain muscle mass, but also to have a nice body shape, you should use a combination of these drugs to create lean muscle mass. A very popular combination is trenbolone acetate + stanozolol. The course is of 5 weeks duration. It is enough to purchase 10 ampoules of 1 ml of Chrone (or other brand of acetate) injectable solution and 100 tablets of stanozolol 10 mg. Tren injections should be administered twice a week in one ampoule + 4 stanozolol tablets per day.
The trenbolone + turinabol regimen is also common. In this regimen, one ampoule of acetate per day is injected and 2 tablets of turinabol per day are taken. It is best to take Turinabol in the morning or afternoon and Tren in the evening. Taking it alone will already give you good results, but you will get the best results when you combine it with other ingredients.
The following drugs are used in combination:
- Turinabol;
- Winstrol; Turinabol; Turinabol; Turinol; Winstrol;
- Metandienone;
- Anavar;
- Testosterone propionate or enanthate.

When used in conjunction with the latter, testosterone enhances the properties of trenbolone but also increases the likelihood of side effects. It should be noted that trenbolone should not be combined with ephedrine and clenbuterol.
