Alpha Pharma TrenaRapid (Trenbolone Acetate, 10 ml, 100mg/ml) is a very well-known injectable anabolic steroid, and milligram for milligram it is the most powerful anabolic steroid commercially and conventionally available. It is an anabolic steroid that tends to invoke both intimidation as well as amazement among those who read about it. The truth is that although Trenbolone is not as harsh of an anabolic steroid as many make it out to be, it is by no means a beginner compound and does need to be taken seriously when the use of it is considered. It is typically used by intermediate to advanced level anabolic steroid users, and seldom used by beginners until several cycles of experience has been built up.

Trenbolone is a derivative of Nandrolone (Deca-Durabolin), and alongside Nandrolone, is in the family of anabolic steroids known as 19-nor compounds. This category of 19-nor steroids is named as such due to the fact that these compounds contain a specific alteration at the 19thcarbon on the anabolic steroid’s molecular structure. This alteration, which is the removal of the 19th carbon, is not seen in any other anabolic steroid classes. It also contains other alterations in this area that grant it enhanced androgenic strength (its ability to bind at a much greater strength to the androgen receptor), as well as a high degree of resistance to metabolic breakdown within the body.

Trenbolone, as a result, expresses five times the androgenic and anabolic strength of Testosterone, with a rating of 500 for each. It also expresses characteristics that grant it the ability to promote weight gain with nearly all of it being muscle mass, and no water retention. Trenbolone has also been found to stimulate endogenous production of the very anabolic hormone IGF-1 (Insulin-like Growth Factor 1) in muscle tissue, adding to its anabolic capabilities. Ultimately, the reason for Trenbolone’s inability to make the user hold onto water and become bloated is due to the fact that its chemical modifications render it unable to aromatize into Estrogen at any dose what so ever.

Three major esterified forms of Trenbolone exist: Trenbolone Acetate, Trenbolone Enanthate, and Trenbolone Hexahydrobenzylcarbonate. The most popular and most widely used of the three is the fast-acting acetate variant. Trenbolone’s history generally begins in 1967, where it was studied repeatedly in France by Roussel-UCLAF. It was eventually picked up by Hosescht in England and manufactured in its acetate ester format, and sold under the brand name of Finajet. In France, Roussel marketed it as Finaject. Both companies were in reality owned and operated by Roussel AG of Germany. Both brand names of the same product (Trenbolone Acetate) were used on the prescription drug market as human grade medicines before they were discontinued and disapproved for use in humans towards the 1980s. Trenbolone Hexahydrobenzylcarbonate was sold under the brand name Parabolan as well during this time before encountering the same fate as the other two in the 1990s.

Today, Tren remains officially utilized as a veterinary drug, mostly in the application of promoting mass in cattle used to provide food. It remains a peculiar compound of interest to the medical establishment, however, as scientific studies continue to continue with Trenbolone, with scientists discovering new applications for human use and recommending its re-introduction as a human grade medicine. To date, however, Trenbolone is still unapproved for human use by the FDA and all current Trenbolone products are generally underground lab (UGL) products.

Trenbolone Cycles and Uses

Trenbolone cycles are very effective as either fat loss or muscle building mass cycles. As an effective muscle and mass builder, Trenbolone has been shown to bind to the receptors of catabolic hormones and effectively block those hormones from engaging in catabolic signaling to muscle cells. This is of particular importance when it comes to the catabolic hormone Cortisol, which Trenbolone should effectively be able to inhibit. Thus, we can see here how even just through the anti-catabolic effects at the cellular level, Trenbolone should be an excellent compound for cutting cycles during dieting or pre-contest phases where catabolism is an issue. Furthermore, Trenbolone’s effectiveness as a fat loss agent is well documented through its incredible nutrient partitioning effects. We also know that androgen receptors indeed exist in fat cells and play a role in fat loss when activated, especially the stronger an androgen binds to this receptor. In the arena of mass and bulking, Trenbolone has demonstrated considerable ability to increase nitrogen retention within muscle tissue.

For cutting cycles, Tren Ace, for example, is normally stacked with Testosterone Propionate for an 8 – 10 week cycle. Additional compounds with similar effects that assist similar goals (such as fat loss) can also be utilized, such as Anavar (Oxandrolone). For bulking purposes, Trenbolone is normally stacked alongside a solid base of some form of Testosterone (for bulking, usually Testosterone Enanthate), and a similar type of oral compound can be used alongside these, such as Dianabol (Methandrostenolone). An additional injectable, such as Boldenone (Equipoise) can also be utilized during bulking cycles.

Trenbolone Dosages and Administration

Trenbolone is one particular compound whereby massive or large dosages are not necessary by any means. As a compound that is five times the strength of Testosterone itself, there is no need to utilize even ‘moderate’ dosages to achieve desired effects and goals. A little goes a long way when it comes to Trenbolone.

Most beginners would do well with 50mg every other day of Trenbolone Acetate (for a total of 200mg weekly) and is more than enough for staving off muscle loss during a cut. Intermediate Trenbolone dosages venture into the 75 – 100mg every other day range (a total of 300 – 400mg per week), and generally produces stunning changes in the physique. There is seldom a requirement – even for advanced users – to venture beyond this dosage range, as Trenbolone is a very powerful compound that carries with it increased discomfort in the form of side effects in proportion to the dosage used. With that being said, most casual advanced users will not venture beyond 400 – 600mg per week, and only extreme professional and competitive bodybuilders have been known to go higher than this.
