Trenbolone enanthate and acetate are the most common variants of trenbolone, but in addition to the radical effect also mainly because of its good availability. In addition to these two variants of trenbolone, the hexahydrobenzylcarbonate is regarded as the rarely available secret weapon under the trenbolone, because of its low dosage, while at the same time being highly potent. All you should know about this topic is here:


Trenbolone hexahydrobenzylcarbonate is an injectable anabolic androgenic steroid originally produced in France, at that time known as Parabolan, containing the active substance trenbolone hexahydrobenzylcarbonate, also known as cyclohexylmethylcarbonate. Hardly any other anabolic androgenic steroid was as popular as Parabolan, and there were hardly so many myths about any other anabolic androgenic steroid.

At the time, trenbolone was by no means as known and popular as it is today, due to the fact that there were hardly any steroids containing trenbolone as the active substance. Prior to trenbolone hexahydrobenzylcarbonate, steroid users wishing to use trenbolone were directed to the veterinary steroid Finaject containing trenbolone acetate and taken from the market in the late 1980s. In contrast to Finaject, trenbolone hexahydrobenzylcarbonate was intended for use in humans and is still the only trenbolone product produced by a legitimate pharmaceutical company for human use. In addition to this, the Parabolan was only available in France worldwide, which, as expected, severely restricted its availability.


Trenbolone hexahydrobenzylcarbonate is a trenbolone molecule to which a hexahydrobenzylcarbonate or cyclohexylmethylcarbonate ester has been added in order to allow a longer availability of the actual active substance trenbolone in the body. Esterified anabolic steroids are inactive in the esterified form in the body and are only activated when the ester is separated and the active substance is thus present in free, unesterified form. The longer the ester is, the more difficult it is for the body to separate it from the active substance molecule, and the slower the release of the active substance is, resulting in a kind of depot effect. Since the hexahydrobenzylcarbonate ester is a relatively long ester, Parabolan has a half-life in the body, which is between 3 and 6 days, depending on the source. The original French Parabolan was available in ampoules each containing 1.5 ml of oily solution containing 76 mg of trenbolone hexahydrobenzylcarbonate (cyclohexylmethylcarbonate), which corresponds to approximately 50 mg of free trenbolone.

Since trenbolone hexahydrobenzylcarbonate is an esterified trenbolone, it has the same effects and side effects as all other trenbolone variants. Trenbolone hexahydrobenzylcarbonate is strongly anabolic and strongly androgenic and cannot be converted due to its structure neither by the aromatase enzyme into estrogen nor by the 5-alpha reductase enzyme into a dihydro active substance. Trenbolone hexahydrobenzylcarbonate is especially used during dieting and competition preparation due to the strong androgenic effect and the absence of conversion into estrogen. Androgen receptors are found in the body both on the muscle cells and on the fat cells, while stimulating the androgen receptors of the muscle cells promotes muscle growth and stimulating the androgen receptors of the fat cells increases fat burning. Trenbolone hexahydrobenzylcarbonate also promotes the maintenance and build-up of muscle mass and the reduction of body fat. In addition, it has a strong anticatabolic effect which is due inter alia to the fact that trenbolone on one hand prevents the conversion of cortisone into catabolic cortisol and, on the other hand, blocks the glucocorticoid receptors on which cortisol develops its catabolic effect. Thus, almost complete suppression of the cortisol effect can be achieved.


Unfortunately, trenbolone hexahydrobenzylcarbonate, like all other trenbolone variants, is also a 19-nortestosterone derivative, which means that trenbolone hexahydrobenzylcarbonate acts as progestin. This means nothing else but that trenbolone can dock directly to the progesterone receptor. The binding affinity of trenbolone for the progesterone receptor is about 60% of the binding affinity of progesterone itself. In sensitively reacting users of trenbolone hexahydrobenzylcarbonate, this can lead to side effects such as water retention and a so-called tren-gyno, which cannot be counteracted by an aromatase inhibitor such as Arimidex or an estrogen receptor blocker such as tamoxifen (Nolvadex). The combination of strong androgenic activity and the fact that trenbolone is a progestin leads to the fact that trenbolone hexahydrobenzylcarbonate suppresses the body's own testosterone production quickly and sustainably.


Parabolan is a very good example of how much the usual dosages of anabolic androgenic steroids have changed over the years. Originally, various "steroid gurus" had warned not to exceed a dose of two ampoules of trenbolone hexahydrobenzylcarbonate per week, equivalent to 152 mg of trenbolone hexahydrobenzylcarbonate (cyclohexylmethylcarbonate) at that time, and that of the steroid gurus who were known for their excessive dosages and experimentation with highly dangerous active substances. During the period when original French Parabolan was available, the dosages observed in practice were in the range of 2 to 3 ampoules of Parabolan per week, which corresponded 152 to 228 mg trenbolone hexahydrobenzylcarbonate per week and all users were enthusiastic about the effect obtained. Nowadays, the doses observed at trenbolone are more likely to be in the range of 76-152 mg of trenbolone hexahydrobenzylcarbonate (cyclohexylmethylcarbonate) per day or every other day, 1-2 ampoules each or every other day.
