Trenbolone (Tren) is considered to be the most powerful androgenic-anabolic steroid (AAS) available, with an exceptionally high ratio of anabolic to androgenic effects. This means Tren has extremely powerful effects of both the anabolic and androgenic types and is not the best choice for your first steroid cycle.

Unlike other steroids out there, Tren has no current approved medical use for humans and was mainly developed for use in the veterinary world. Nowadays, only Trenbolone Acetate continues to be used in veterinary medicine.

When used as an androgen and anabolic steroid by bodybuilders and athletes, Trenbolone is often stacked with other compounds. Most importantly is a combined use of Tren with a testosterone ester compound – usually with a short ester like Testosterone Propionate, to help with suppressed testosterone production caused by Tren.

Trenbolone itself is five times as powerful as testosterone and therefore should be used with caution even by intermediate steroid users.

If you’ve heard of the Nandrolone steroid, more commonly called Deca Durabolin, then you’ll know just how powerful it is.

Trenbolone is a derivative of Nandrolone with a slight modification to the chemical structure, which is enough to give Trenbolone different effects on the body.

Trenbolone (Tren) is considered superior to the original nandrolone compound on its own with the main benefits being: Tren has a slower metabolism, attaches to the androgen receptor better, prevents aromatic compounds from forming.

Besides the exceptionally powerful results Tren is capable of delivering, the other huge benefit of this steroid is that it does not aromatize so you don’t get the estrogen conversion that we see with most other androgen and anabolic steroid compounds.

A major advantage of Tren is that it doesn’t cause water retention like so many other steroids do which is one of the big reasons it’s so popular cutting and gaining a super hard and ripped physique without the bloat.

On the downside, similar side effects to other steroids are still possible because Tren is a progestin which, sorry to say, can also make you more prone to gyno. Because people often combine an aromatizing steroid like testosterone with Tren, anti-estrogen treatment is often still undertaken and post cycle therapy (PCT) is still mandatory following a Tren cycle.

Trenbolone Forms: Trenbolone Acetate vs Trenbolone Enanthate vs Parabolan (Tren-Hex)

The three main forms or esters of Trenbolone are Trenbolone Enanthate, Trenbolone Acetate and Trenbolone hexahydrobenzylcarbonate (Tren-Hex for short or Parabolan as the brand name). These are all developed as prodrugs, meaning they are an inactive form until they are metabolized in the body, where they then are converted into Trenbolone.

Trenbolone acetate was developed for veterinary use in cattle to improve muscle mass. It has an elimination half life of just two to three days. This is considered to be the most potent of these three Tren esters with the highest percentage of active Trenbolone per 100mg.

Because it is so fast acting, Tren acetate requires more frequent injections in a cycle, with every other day being the most common protocol. Trenbolone acetate is the most commonly used form of Tren by anabolic steroid users.

Trenbolone enanthate has a 7 day half life and this is an ester that was never released to market, but can still be found on the black market today.

Tren enanthate is a slower acting form but brings the same benefits like huge increases in muscle mass, nitrogen retention, boosted protein synthesis and a big gain in endurance.

Parabolan or Tren-hex has a half life of 14 days and is a long acting injectable compound which was discontinued in production in the late 1990s. Besides the longer half life, Parabolan is considered to have the same properties and effects as Trenbolone acetate.

Although some people might be tempted to combine multiple forms of Tren in a cycle, this has no benefit since they are all so chemically similar. Instead, it would result in a dangerously high dosage and magnification of side effects. Stacking Trenbolone with other types of steroids however can be very beneficial for more experienced users.
Trenbolone Acetate (Tren-Ace) Cycle

This is an exceptionally fast acting form of Trenbolone with a rapid half life that quickly gets the compound taken up into the bloodstream. It has a half life of just three days. Although the effects of Tren-Ace are virtually identical to those of Tren-E, Tren Ace is hard to beat.

The benefits of using Trenbolone Acetate include massive boost to mass and strength, extremely fast results and excellent muscle hardening. There are also some Tren Ace side effects such as: loss of libido, gyno due to progestin properties, baldness if pre-disposed to it genetically, acne, raised cholesterol and excess sweating.

Beginners should look at using no more than 200mg weekly in a Tren Ace cycle, with 100mg being most recommended. A cycle length of anywhere between 8 and 16 weeks is possible with good results from Tren-Ace.

More advanced users can boost the dosage up to 500mg per week maximum, as long as preparations and awareness for the associated side effects are made. To counter some of these side effects, combining Tren-Ace with a testosterone steroid is often done.
Trenbolone Enanthate (Tren-E) Cycle

Commonly known as Trenabol, this is a derivative of the nandrolone anabolic-androgenic steroid. Tren Enanthate is a long acting form of Trenbolone. As with all Trenbolone cycles, it’s always recommended to use Trenabol alongside testosterone to make up for the slow down in natural testosterone production.

The main benefits of Trenabol include: significantly boosted protein synthesis, enhanced nitrogen retention to keep the body in an anabolic state, boosted oxygen supply to the muscles, improved IGF-1 function, fast recovery, increased endurance and more. Tren Enanthate is useful for both bulking and cutting

Possible side effects include: low libido and erectile dysfunction if not used with testosterone, high cholesterol, acne, head hair loss, gynecomastia and insomnia.

An 8-16 week cycle is suitable for a Tren enanthate cycle at 100 to 300mg weekly for a beginner to intermediate user. This is still considered a very strong dosage of Tren with powerful effects. Experienced users of Trenabol increase dosage to 500mg per week, either in multiple injections or in the case of highly experienced people, in one single injection.
Trenbolone Hexahydrobenzylcarbonate (Tren-Hex) Cycle

Known under its brand name Parabolan, Tren-Hex is a much more longer acting and slower release form of Trenbolone compared with the acetate variant. Tren-Hex has a much longer half life of 14 days and therefore requires less frequent injections to maintain optimal levels.

Like all forms of Tren, high doses of Tren-Hex aren’t required due to the fact this is such a powerful steroid (five times as powerful as testosterone). Tren Hex is great for bulking, strength and lean mass gains, but also powerful for cutting and fat loss. It does not aromatize into estrogen so no bloating or water retention and can deliver a hard, vascular physique with the right diet.

Possible side effects of using Tren Hex are coughing fits after injecting, insomnia, excessive sweating, mood changes and aggression, acne, hair loss on the head and body hair growth.

Your tolerance levels will determine the best dosage for your needs, as will the inclusion of other compounds in your cycle. First time users should start with a low dose of this very powerful steroid.

A common dosage cycle is between 150mg and 250mg weekly. But more advanced users might take the dosage to over 400mg weekly – this is not recommended for beginners and comes with considerably higher risks of side effects.
Typical Trenbolone Cycles
Tren Cycle For Bulking

A 12 week cycle for bulking can consists of a steady 200mg-400mg trenbolone per week for the whole 12 weeks, depending which other compounds are being used and how powerful they are. A common stack includes the use of a testosterone ester and Winstrol for the last few weeks of a cycle.
