Trenbolone side effects – Everything you need to know

trenbolone side effects

A quick search online about trenbolone will turn up plenty of images of bulging muscles and poppin’ veins, with promises of getting bigger, leaner and stronger.

Since trenbolone is well known as one of the most powerful anabolic steroids around, it’s no surprise that the idea of tren bodybuilding is very tempting.

But before you go grabbing a pack of needles and gearing yourself up for huge tren cycle results, it’s important to pay attention to trenbolone’s side effects and potential impact on your body. And we don’t just mean getting stacked!

Before we get stuck in, let’s take a look at how trenbolone works and why tren bodybuilding is so popular.

What is trenbolone?

Developed in the 1960s, trenbolone is considered an incredibly powerful anabolic steroid. While tren bodybuilding is well known in fitness circles, this wasn’t the original intention of trenbolone. Yep, that’s right – it was created for cattle.

Originally developed to increase muscle mass and appetite in cattle, it wasn’t until 1980 that a new form of trenbolone was developed for people. However, yet again, trenbolone’s purpose wasn’t to help men get stacked at the gym. Its sole purpose was to help those suffering from AIDS, muscle wasting and osteoporosis – later taken off the marketing in 1997.

Since tren side effects are so prominent, it’s no surprise that trenbolone is no longer legal. In terms of how trenbolone has been developed, tren is considered a modified form of another anabolic steroid you’ll most likely know – Nandrolone – Frequently referred to as Deca-Durabolin or Durabolin.

This drug has similar effects to testosterone, with slightly milder side effects.

Many bodybuilders choose to stack nandrolone and testosterone, in the hope of achieving even BIGGER gains.

Since tren cannot be converted into estrogen (unlike other steroids), tren’s side effect of man boobs is reduced – kinda. But before we tell you more about trenbolone side effects, let’s take a look at how trenbolone works.

Trenbolone results: Why do people take tren?

Why is trenbolone so popular? Despite being produced for cattle, tren bodybuilding still very much remains in bodybuilding circles.

With less risk of man boobs in comparison to other anabolic steroids, trenbolone is incredibly powerful even at low doses. Since trenbolone is so strong, dosage can start as low as 200mg per week, split into injections every other day.

If you’re a little more advanced, this can increase to 400 to 500mg. At extreme levels, a trenbolone dose can go as high as 800 to 1000mg! Crazy (and very unsafe) stuff.

As well as helping you get hench, trenbolone can also enhance the production of red blood cells – therefore improving your circulation, equalling even more strength and stamina.

When we take a closer look at how steroids work and why trenbolone remains so popular, it’s important to pay attention to how our bodies respond to anabolic steroids.

These androgenic hormones come flooding in the form of steroids, raising your testosterone levels – therefore telling your body to build more muscle.

However, many beginner steroid users don’t realise that all anabolic steroids are derivatives of testosterone – meaning they more or less work the same way. Although their side effects can quickly cross over.

But what other tren cycle results can you expect?

Tren cycle results

So what is it that makes trenbolone so special? Let’s talk about tren cycle results.

Trenbolone, also frequently referred to as ‘tren’ is well known for its ability to increase the production of the insulin-like Growth Factor 1 (IGF-1) hormone, which plays a key role in muscle growth.

During studies, men using trenbolone gained 7 pounds of muscle on average, while adding 70 pounds to their squat and bench press weight.

By stimulating the production of new cells, trenbolone promotes growth, helping you achieve the body you dream of.

If you’re looking to build muscle fast – faster than testosterone – trenbolone will help you achieve this. Tren will support you in bulking up, cutting fat and building strength – fast.

But, do these tren cycle results come at a cost? Sorry guys, of course, they do…

What to expect on tren: Trenbolone side effects

During a tren cycle, you may gain muscle especially fast during the first 8-12 weeks. But don’t get too excited, however, as these gains can rapidly disappear as quickly as they arrived.

Tren’s side effects tend to cross over with many other illegal anabolic steroids. While bodybuilders who may have previously just taken testosterone faced a number of problems, some of these are very much the same as tren side effects.

Many found that when taking testosterone that their increase in muscle mass would get even smaller for every additional increase in dosage. This would mean that gains of 14 pound in the initial 10 weeks could easily decrease to 9 or 10 pounds over the next 10 weeks – despite the dose doubling.

But why does this happen? Research suggests that our bodies become resistant to the effects of testosterone over time. In short, taking trenbolone will boost your testosterone levels momentarily, but then damage your body’s natural production post-cycle.

Since your body’s levels have been artificially increased, the body works to lower this unusual amount to bring your T levels back to normal.

While it’s easy to get caught up dreaming about the results of trenbolone and transforming your body into a muscle machine, is it worth it?

Oily skin/Acne

If you’re wondering what to expect on Tren, be prepared to go back to your acne-ridden youth. One tren side effect is just that – super oily skin. While our skin produces natural oils, taking trenbolone pushes your sebaceous glands up a notch, producing more oil than your skin needs.

This can make you feel pretty clammy and gross, plus lead to some horrendous acne.

While you may be happy that you’re getting stacked, a face full of pimples is probably not the look you were going for.

Natural testosterone reduction and testicle size

As we already mentioned briefly, one tren side effect (much like many other steroids) is its power to reduce your body’s natural testosterone production.

Since steroids such as trenbolone increase your T levels artificially, when you stop your tren bodybuilding cycle, your testosterone levels don’t simply bounce back.

And so, sadly, one of the body’s main ways to reduce testosterone production is to reduce testicle size. But the size of your testes aside, a dent in your body’s testosterone can cause even more issues. Yep, your sex life can quickly suffer.

Otherwise known as ‘tren dick’ – Trenbolone’s side effects on the body means a huge decrease in testosterone, which can lead to erectile dysfunction (ED) and a lack of sex drive. Unfortunately, like every other steroid, this side effect of trenbolone isn’t avoidable.

The only way to increase your body’s natural testosterone production and testicle size is to stop taking steroids. Even then… You’re looking at several months to get back to normal.

Gynecomastia (man boobs)

But wait, trenbolone can’t be converted into estrogen and therefore can’t cause breast growth… Right? Well, it kinda can.

While tren may not increase estrogen levels, it can increase another feminizing hormone known as progesterone. This hormone is key for a number of bodily processes, including brain function, metabolism and the production of other hormones.

However, it is known the most for being the primary hormone involved in breast growth, menstruation and fertility.

Despite there being plenty of room for further research, some men have also reported lactation during a tren cycle. Yes, you read that right.

Not quite the hormone or desired look you were going for.

Tren cough

This is a pretty common trenbolone side effect, that men experience immediately after injecting trenbolone. This can last somewhere between 5 and 10 minutes and usually disappears soon after, or the cough becomes less severe.

But why does this occur? Tren cough could be due to trenbolone’s impact on inflammatory compounds called prostaglandins.

It could be that trenbolone immediately irritates lung tissue, causing you to cough as a way to expel the irritation.

Hair loss

A common side effect of many androgenic steroids, and particularly unattractive – hair loss.

If male-pattern baldness is already in your family, stay well clear of trenbolone since it can encourage this even quicker. Unless you fancy shaving all your hair off, it may be best to give trenbolone a miss.

Other trenbolone side effects

We could be here all day listing the many trenbolone side effects and side effects of popular anabolic steroids, but here’s a shortlist of other side effects you may experience while taking trenbolone:

  • Increased blood pressure
  • Insomnia
  • Night sweats
  • Decrease in endurance
  • Heightened risk of brain, prostate and breast cancer
  • Heightened risk of permanent testicular atrophy, insulin resistance, heart disease and nose bleeds
  • Aggression

Is trenbolone worth it?

Trenbolone is a serious and powerful illegal steroid, that we’d recommend staying clear of, especially if you’re a beginner. If you’ve never done a tren cycle, it’s probably best left that way!

Pumping your body with artificial chemicals is just not worth the health risks, despite the potential gains. And even then, those gains can quickly disappear as quickly as they arrived.

Why not try a legal, risk-free alternative?
