Trenbolone side effects vary in intensity from mild to severe depending on the amount you use and the supplements you choose to use with it.

Although Trenbolone is very powerful and it can produce significant side effects, the good news is that you can mitigate the majority of them by using the product responsibly and adding the right compounds to your stack. Here are the different categories of side effects and what you can do to prevent them.

Prevent Trenbolone Side Effects with Proper Dosing and Cycling

By far, the best way to prevent even the most serious side effects of Trenbolone is to use it responsibly. This means using the right dose for your particular needs and remembering to tailor your cycle length to that dose. The chart below will serve as a point of reference.

Remember that different people will respond to Trenbolone in different ways. You may find that 500mg per week is your upper limit and a higher dose causes unwanted Tren side effects. The goal is to find a balance between the results you want and the side effects you don’t.

Most Common Trenbolone Side Effects

Though you can mitigate many of the side effects of Trenbolone, there are some that almost everyone will experience to some degree or another. They are difficult to avoid, but you can treat the symptoms as they arise with over-the-counter products.

  • Oily skin with or without acne. Hormonal fluctuations may stimulate your sebaceous glands to produce more oil than normal. For some, this is only minimal, but for others, it can be quite severe and lead to breakouts. Though this is mostly unpreventable, you can use over-the-counter acne products containing salicylic acid or benzoyl peroxide to control oily skin. For an oily scalp, consider using a good clarifying shampoo designed to help remove buildup from your hair.
  • Gastrointestinal upset. Like most other Tren ace side effects, this is one that you may or may not experience, and it is far more common with the oral forms of the steroid. Taking your pill with food may help relieve some of the gastrointestinal Tren steroid side effects, but if not, you can use a variety of over-the-counter medications to treat symptoms like nausea, heartburn, constipation, or diarrhea.
  • Mood changes. Hormone changes are notorious for causing mood swings, making this one of the most common side effects of Tren. Unfortunately, there is little you can do to mitigate this, though some people find that gradually increasing their Tren dose over the first week or two alleviates the more drastic mood swings.

These Tren side effects are common, and most people will experience one or more. However, for most, they are quite mild and will get better over time. If any of these Trenbolone side effects become severe, you should stop using the steroid and see your doctor.


One of the selling points is that there are no estrogenic Tren side effects. Trenbolone does not convert to estrogen in the body, so water retention simply does not occur. However, what many users fail to realize is that Tren has a strong progestin nature. Progestin can stimulate the mammary tissue in men and women alike, which could cause gynecomastia if it is not kept in check. Anti-estrogen medications can certainly help prevent this.


There are some androgenic Trenbolone side effects to keep in mind, as well. Acne, hair loss, and the accelerated growth of body hair are all possibilities. The good news is that these Tren side effects only seem to affect men who are predisposed to such conditions. This means that if your father and brother have male-pattern baldness, or even if you have shown the signs yourself, there is a chance that Tren will speed it up. Unfortunately, if you have these genetic predispositions, there is very little you can do to ward off these side effects. You need to discern whether the benefits of using Tren outweigh these risks.


Trenbolone Side EffectsAlmost every single anabolic steroid available to you today will suppress your body’s ability to produce its own testosterone, and Tren is certainly no different. Many websites claim that testosterone suppression is not one of the Tren side effects, but this is undeniably false. Tren binds to the same receptors as testosterone, which puts a stop to your body’s chemical signals telling the testicles to make more. As such, within three weeks of starting a cycle, your body no longer makes testosterone on its own. To combat this, all you have to do is include exogenous testosterone during your cycle and follow up with post-cycle therapy.


The cardiovascular Trenbolone side effects are the greatest concern. Studies have shown that this steroid can suppress good (HDL) cholesterol and increase bad (LDL) cholesterol in relatively short order. In fact, many believe that Tren is the hardest injectable steroid on your heart. You can absolutely control your cholesterol with diet and supplements. Consume as little saturated fat and simple sugars as possible, and use fish oil or omega-3 acids in therapeutic doses. If you have preexisting cholesterol issues, you should not use Trenbolone.

Tren Cough

One of the more unusual and mysterious Trenbolone acetate side effects is known as “Tren cough”, and it only occurs when using the injectable form. Essentially, it is a series of symptoms, including a hacking cough, that occurs immediately after injection and lasts between 30 and 60 seconds. It occurs when a small amount of the injected Tren makes its way into the bloodstream via capillaries or other small blood vessels. When this happens, the steroid goes straight to the lungs and creates the urge to cough. For some, the coughing is preceded by a metallic taste in the mouth and a tightness in the chest. The best way to mitigate this risk involves learning proper injection methods and using the right needle size for your injection location.

As you can see, despite its popularity, you should remain vigilant and aware in terms of Trenbolone side effects. You can mitigate most of them with supplements and diet, but if you have preexisting male pattern baldness or issues with your cholesterol, it is incredibly important to consider the possible risks before you start a cycle with Tren.
