Updated 28 August 2017

Trenbolone is rated as one of the most potent anabolic steroids available today, insane strength gains over a short period are easily accomplished when using Trenbolone, even at low dosages. Trenbolone is a derivative of Nandrolone, and as with Deca Durabolin, it is a 19-nor compound anabolic steroid. Steroids in the 19-nor family have an alteration at the 19th carbon of its chemical structure. These alterations to Trenbolones chemical structure are the reason for its incredible strength and muscle building properties, compared to Testosterone, Trenbolone has an Anabolic rating of 500 and Androgenic rating of 500, which is five times higher than Testosterone.

There are currently three different types of Trenbolone available today, Trenbolone Acetate, Trenbolone Enanthate and Trenbolone Hexahydrobenzylcarbonate. Many people choose the acetate version due to its short half-life, if the side effects become unbearable, the user can stop immediately, and within a few days, the drug will be out their system.


Although many bodybuilders take large dosages of Trenbolone, this is not needed. Even at very low dosages, Trenbolone can give amazing results. For newcomers to this steroid, a dosage of 150 to 200mg a week is more than enough to see good results. Dosages for more experienced users typically range between 200 and 400mg a week, with some users going above this. Trenbolone is a powerful drug, and the side effects associated with Trenbolone usage can often be quite harsh, taking a lower dosage will help keep side effects under control.

Trenbolone Cutting Cycle

Trenbolone is almost always incorporated into cutting cycles by experienced bodybuilders.

This is for many different reasons:

  • Trenbolone does not convert to Estrogen, and therefore there is zero water retention associated with using this steroid.
  • Due to Trenbolone being so potent, bodybuilders can maintain their muscle mass and sometimes even build muscle when on a calorie restricted diet.
  • Trenbolone helps burn fat.
  • Gives muscles a harder and more vascular look.

There are many different ways to run a cutting cycle consisting of Trenbolone, many users either go the simple route and use Trenbolone with Testosterone and nothing else. While other more experienced users combine many different anabolic steroids and fat burners into their cycle.

Example of Trenbolone cutting cycle:

 WinstrolTrenbolone AcetateTestosterone Propionate
Week 150mg/day80mg/every second day150mg/every second day
Week 250mg/day80mg/every second day150mg/every second day
Week 350mg/day80mg/every second day150mg/every second day
Week 450mg/day80mg/every second day150mg/every second day
Week 550mg/day80mg/every second day150mg/every second day
Week 680mg/every second day150mg/every second day
Week 780mg/every second day150mg/every second day
Week 880mg/every second day150mg/every second day

Always keep an AI (Nolvadex) or SERM (Letrozole) on hand to combat estrogen side effects, for Trenbolone a product such as Cabergoline may be needed to help with progesterone related side effects. Once the cycle is complete, make sure to follow a proper PCT protocol. The above cycle is for entertainment purposes only and is not medical advice.

Trenbolone Bulking Cycle

Trenbolone is an amazing and diverse compound, and it is one of the few steroids that is extremely effective in both cutting and bulking cycles. When combined with a high calorie and protein diet, insane amounts of muscle can be built. For bulking cycles, Trenbolone Enanthate is often used with Dianabol and Testosterone Cypionate.

Example of Trenbolone bulking cycle:

 DianabolTestosterone CypionateTrenbolone EnanthateNolvadex (if needed)
Week 150mg/day500mg/week300mg/week20mg/day

Side Effects

Tren does not convert to Estrogen. Therefore most side effects associated with Trenbolone are due to its high Androgenic rating. Side effects common with Trenbolone that are rarely seen with other steroids consist of excessive sweating and insomnia. Many users claim to sweat a lot during the night and often wake up in the morning with their bedding soaked in sweat.

Some side effects consist of:

  • Acne
  • Male pattern baldness
  • Gynecomastia (caused by Progesterone and not Estrogen. Cabergoline or Pramipexole will be needed to prevent this)
  • Increased hair growth
  • Aggression (Trenbolone is known to cause serious anger issues in users)
  • Decreased appetite
  • High blood pressure
  • High cholesterol

Most of the side effects can be prevented or reduced by using a lower dosage, this is why it is always recommended to use Tren at a low dosage, it is a very powerful compound and, many people underestimate this.
